Special Interests and Achievments
- Basic genetics and physiology studies of the spontaneous mutations of ripening inhibitor genes in tomatoes and the consequent exploitation of the knowledge resulted in the original development of long shelf-life tomatoes, thus revolutionizing the fresh market industry.
NisuyWin
NisuyWin Version 4.0 Download information
NisuyWin is a Windows version of the old DOS program "Nisuy". This program computes Analysis of Variance and Multiple Range tests. It is specially adapted for analyzing agricultural field experiments, but it can also be used for other types of experiments. "NisuyWin" is the English version, for details about downloading the Hebrew version of the program read below.

Cotton2K Model version 4.0
A. Marani
Version historyThe COTTON2K cotton simulation model is descended from GOSSYM-COMAX. Its main purpose was to make the model more useful for conditions of cotton production under irrigation in the arid regions of the Western USA. Since many changes have been made in the model, it has been given a new name: CALGOS (for CALifornia GOSsym). The present version, which is completely revised has been renamed COTTON2K.

Keep vegetables fresh for a month, sans fridge
A new technique developed by Hebrew University researchers that extend the life of vegetables for weeks without refrigeration could help break the cycle of poverty among rural farmers in the developing world

... The new technology was invented by Dr. Rivka Elbaum, from the Faculty of Agricultural, Food and Environmental Quality Sciences, Robert H. Smith Institute of Plant Sciences and Genetics in Agriculture at the Hebrew University. It entails dipping the cut leaves into the solution, which is a secret, and has been patented in the United States and Israel.
In a number of experiments, the solution was shown to delay senescence and chlorophyll loss in lettuce leaves as well as in Arabidopsis, a small flowering plant related to cabbage and mustard. The system will also work with other leafy vegetables, such as celery, spinach, cabbage, kale, parsley, basil, cauliflower, and broccoli, the university said.

Stable climate and plant domestication linked
January 13, 2010 Sustainable farming and the introduction of new crops relies on a relatively stable climate, not dramatic conditions attributable to climate change.

Basing their argument on evolutionary, ecological, genetic and agronomic considerations, researchers demonstrate why climate change is not the likely cause of plant domestication in the Near East.

which determines the number of grains per inflorescence of cereals such as bread wheat or barley. Nonetheless, until recently little was known about its genetic basis. Whilst investigating floret fertility, a group of researchers have now discovered the locus Grain Number Increase 1 (GNI1), an important contributor to floret fertility. A writeup from Science Daily of an international collaboration, including researchers from the Robert H. Smith Faculty of Agriculture, to decode the genetic basis of floret fertility in wheat. The research was published in PNAS:
