Horticulture Newsletter - November 2010

1 Nov 2010

As Europe and America limp slowly out of recession, many eastern countries continue to surge ahead. Several reports have questioned their ability to feed themselves. However, in an article below abridged from an original in the FPJ Journal, Rebecca Lewis of Promar International sounds a warning and describes the impact their horticultural industries could have on the UK fresh produce industry.


When East Meets West: growing the Asian link

In the next ten years, Asia's population will increase by more than 10 percent - an extra 430 million people - which represents well over half of the world's additional population in the period.

The ascent from poverty of large proportions of the population of India and China is well documented, as is the challenge of how these increasingly affluent countries will be fed. Agricultural production in China and India receives substantial investment and in many cases, is rising at an incredible rate. It is by no means focused only on the domestic market. Combined with their phenomenal geographic size, production volumes dwarf most other leading agricultural producing countries. Horticulture is no exception.

applesFor instance, China's apple crop, at 30 million tonnes, is almost seven times larger than its nearest rival, the US. Exports, at 1.2mt, have soared by almost 400% in the last 10 years and still account for less than 5% of the crop.

In India, the mango and grape industries, among others, are specifically targeted by the government for export development. Other products such as soft fruit and cut flowers follow behind.

Elsewhere in Asia, Thailand has already established itself as a major player in processed horticultural produce, such as canned pineapples and more niche products like individual quick-frozen products, as well as exotic items including baby corn, speciality Asian vegetables and asparagus.

Shifting social trends are changing the face of consumption, the Asian consumer and in time, the development of the supply chain. One of the key features is the rise of modern forms of retailing. In India, this only accounts for around 5% of the market at the moment, but in China it is already around 25% and growing fast. The so-called Pac Rim markets, such as Korea and Taiwan, are also seeing the rapid growth of more modern forms of retailing.

Tesco ChinaThere may be niche opportunities for European produce in Asia, but overall the balance of trade is likely to be in the other direction. That is not to say there are no opportunities for the UK. Far from it, in fact UK retailers, for example, led by Tesco, are already eyeing the future potential of these markets.

As both export and organised modern urban retail markets develop, there will also be an increased need for high-class traceability, accreditation and food safety systems, supply chain logistics, environmental technologies, corporate social responsibility strategies, new product development, innovation and processing technology.

This is where the UK is inherently strong. A foreign education is still highly valued and many UK agri-food oriented universities and colleges are already actively marketing and recruiting in Asia, particularly in China, to help provide the skills and knowledge these food industries of the future will require.

Asian agri food businesses will not just cause a ripple in Western markets in the next 10 years - it could be more like a tidal wave. The UK produce sector needs to ensure it can ride with the wave, not get caught in its wake and only wishing it had seen it coming. It's already on the way.

This requires vision and planning because once the wave arrives, it could already be too late. How we respond to all of this will be critical. A positive response could see new investment in production and distribution, as well as the opportunity for the UK to develop knowledge-based services back into Asian markets.

A negative or closed response might well see Asia look elsewhere in the EU or in the US, Latin America or Australasia and leave the UK out in the cold. A case of catching Asian flu - or not - as the case might be?

Medicinal Plant of the Month

Eucharis amazonica , Galanthus peshmenii and Galanthus reginae-olgae, Amaryllidaceae

eucharis spThe genus Eucharis is made up of 17 species and two naturally occurring hybrids. The name means true (eu) attraction (charis) and refers to the beautiful flowers. Eucharis amazonica, commonly known as the Amazon lily, has been somewhat confused in cultivation with Eucharis grandiflora. The specimen shown in the photos below awaits taxonomic verification by the consultant taxonomist employed by the University of Oxford Botanic Garden. We currently have it labelled as Eucharis amazonica. Whether the correct name be E. amazonica or E. grandiflora the flowers have a beautiful delicate scent and look stunning on the shady floor of the tropical glasshouse.

This bulbous perennial with evergreen leaves requires moist fertile soil in partial shade with a minimum temperature of 10°C to grow well. It flowers in autumn through winter and definitely brightens up the glasshouses on a gloomy day. The Amaryllis family to which this genus belongs is well known for the alkaloids (nitrogen containing naturally occurring compounds biosynthesised from amino acids) it contains. The most medicinally important alkaloid found in Amaryllidaceae plant is galanthamine. This molecule was first isolated in 1952 after being extracted from Galanthus woronowii, a snowdrop species native to Turkey, Russia and Georgia.

Since then many different Amaryllidaceae genera have been found to contain this substance. In Bulgaria, Leucojum aestivum is grown for the commercial extraction of galanthamine, in China the red spider lily, Lycoris radiata is grown for this purpose whilst in the UK there are many acres devoted to cultivation of Narcissus ‘Carlton' to provide the raw material.

Galanthamine has now been used internally for approximately 40 years for the reversal of neuromuscular blockade and for the treatment of neurological conditions such as post-polio paralysis and myasthenia gravis. It was not until the 1990s, however, that galanthamine was licensed as a treatment for Alzheimer's disease. Until last month, galanthamine was only recommended by The National Institute for Health and Clinical Excellence (NICE) for the treatment of moderate to severe Alzheimer's disease thus limiting the number of patients who could like benefit from this drug. However, in early October 2010, NICE updated its recommendations to include patients with mild Alzheimer's disease. Production will need to be increased and although some of the need is met by total chemical synthesis, much of the drug is still extracted directly from plants. One company, Alzeim, are planting a further 60 acres (24ha) in the Black Mountains near Talgarth, and will open a production line at new offices in Brecon before the end of October.

galanthus spAlso in the Amaryllidaceae and already mentioned as the first source of galanthamine are snowdrops. Whilst usually associated with late winter and early spring, the first snowdrops of the season are already blooming. There are a handful of species of autumn flowering snowdrops including Galanthus peshmenii and Galanthus reginae-olgae. It comes as quite a shock to see the dainty flowers on the rock garden or in the alpine house in October - before we've even had the first frost of the season! Still, it's a good warm-up for the snowdrop mania that will arrive in February.

Lord Sainsbury calls for new GM debate
Lord Sainsbury says it is time for a new debate on GM foods as he thinks they will help feed the world population estimated to reach 9bn by 2050. The former science minister claimed it would be foolish for the UK to rule out the technology. More

  • Plan for water shortages
    Following a report from the RASE, using rainfall figures from Rothamsted Research, ADAS is encouraging growers to carry out a water audit and prepare for water shortages. More
  • Better global water management
    Rivers that serve 80% of the world's population are threatened by agricultural runoff, pollution and invasive species, according to a new international study. US researchers studied the effects of a variety of environmental stress factors on water systems. They found that in addition to threatening human lives, pollutants also endanger the biodiversity of 65% of the world's river habitats and put thousands of aquatic wildlife species at risk.
  • Drought threatens much of globe
    We are facing the possibility of widespread drought in the coming decades, but this has yet to be fully recognized by both the public and the climate change research community. Heavily populated countries face a growing threat of severe and prolonged drought in coming decades. More

Oak processionary moth sighted outside London
Thaumatopoeia processioneaThe oak processionary moth (Thaumetopoeia processionea, photo right by Sarefo) has been found in Reading so the pest is no longer contained in Greater London. The caterpillars can cause serious defoliation of oak trees and in Europe they have also been associated with hornbeam, hazel, beech, sweet chestnut and birch. The caterpillars have urticating (irritating) hairs that carry a toxin which can be blown in the wind and cause serious irritation to the skin, eyes and bronchial tubes of humans and animals. They are considered a significant human health problem when populations reach outbreak proportions, such as those in The Netherlands and Belgium in recent years. Trees recently imported from Holland or Germany need to be checked.

  • Further fears - efforts to control pest in London appear to be failing.

Plane trees now threatened
Tree experts at the London's Royal Parks have discovered a new disease called Massaria in around 200 plane trees, necessitating the removal of infected branches before they shear off and fall to the ground. The disease had been previously known in Germany and the Netherlands but was unknown in the United Kingdom until last year. Forestry Commission have warned that its ability to kill individual branches has created a 'risk to public safety'. More

Scientists find genes that help put plants to bed
It is not only people that benefit from a good night's rest - scientists have pinpointed genes that help plants sense when it is dark and time to slow down. A study led by the University of Edinburgh used computer models of gene networks in a simple cress plant to show that certain genes take effect to enable plants to reduce their activity at night and predict when the sun will rise again. The genes allow plants to make tiny adjustments to their internal clock as light changes - a process that is crucial in helping plants to adapt to different lengths of days and changing seasons.

New products
A number of new products were on display at this year's UK stand at HortiFair in Amsterdam, organised by the Commercial Horticultural Association including;

  • Saponins aid root absorption
    Hortifeeds Ltd have introduced HortiWet Organic, a natural plant extract and bio stimulant containing surface tension breaking saponins. By affecting water movement and uptake in the root zone it improves nutrient absorption and increases biological activity in the soil, stimulating plant growth. It can be used via incorporation, flood or drip irrigation and as a foliar spray and is particularly useful in helping plants to recover from stress conditions, The product is now approved for use by organic growers under North American and European legislation.
  • tuta solutionSticky rolls to control tomato leaf miner Tuta absoluta
    Russell IPM has developed Tuta+ sticky rolls to combat tomato leaf miner Tuta absoluta. These pheromone impregnated yellow sticky rolls are designed for use in green houses where beneficial insects are not in use as a biological control agent. The yellow colour of the sticky rolls has the extra advantage of capturing whitefly and aphids providing a one stop solution to combat Tuta absoluta and other soft bodied invasive species present in the green houses. (Photo right by Russell IPM)
  • Red sprouts for Christmas
    Whether you love them or hate them, sprouts are a traditional part of the Christmas menu. Since red is a predominant colour of the season you can now have red sprouts (well purple really) to blend in.

National infrastructure plan - looks good for science?...
The Prime Minister speaking at the CBI conference said the governments aim was to ensure that the UK remains a world leader in science and research by continuing support for the highest value scientific research by maintaining a science budget of £4.6 billion.

... or is science better off without government?
Philip Salter, from the Adam Smith Institute, argues that private funding is vital for translating scientific research into economic growth. Despite the outcry from many in the scientific community over cuts in government spending, he argues this is good news for science as well as for taxpayers. The British Government only started to fund science after the Great War, well after the technological and economic surges of the agricultural and industrial revolutions had taken place. The fact is that these revolutions required no government funding. More

Small genomes grow quicker
Scientists at Kew's Jodrell Laboratory have discovered that Paris japonica, a striking rare native of Japan, has the largest genome of them all - bigger than the human genome and even larger than the previous record holder - the marbled lungfish. The more DNA there is in a genome, the longer it takes for a cell to copy all its DNA and divide. The knock-on effect is that it can take longer for an organism with a larger genome to complete its life cycle. It is no coincidence that many plants living in deserts which must grow quickly after rains have small genomes enabling them to grow rapidly. In contrast, species with large genomes grow much more slowly and are excluded from such habitats. More

Sceletium tortuosumSouth Africa to research mood-lifting plant
For hundreds of years, indigenous South Africans have chewed the indigenous plant, Sceletium tortuosum (photo right by Henry Brisse), to reduce stress, relieve hunger, sedate and elevate moods. Now they have a license to study and market it, and plan to sell it over-the-counter worldwide. More

New route for GM escape
Scientists at the University of Bristol have discovered a previously unknown route by which GM genes may escape into the natural environment. The bacterium Agrobacterium tumefaciens transforms plant tissue as part of its infection process and this natural process provides an important toolbox for scientists to genetically manipulate many species of plants. In the natural environment Agrobacterium and fungi likely encounter each other at plant wound sites raising the possibility of natural gene transfer from bacterium to fungus. The results demonstrate that when placed together on damaged plant tissue, Agrobacterium readily transforms associated fungi with implications for the risk assessment of GM plants generated via Agrobacterium-mediated transformation.
