However, agricultural Trees (like bears) need rest period has been completed in the various kinds and varieties of fruit. Also, it takes some knowledgable engineering to get effective, efficient cooling of the trees at the right time using overhead sprinkling.

Hotter Utah State university Like bears in hibernation, fruit trees must get their winter rest, afterwards they must ac- cumulate a specific amount of solar energy. Both are necessary to develop the buds and blossoms. If both of these happen before the last killing frost in the spring, POW! Much, if not all of the fruit crop is lost! Thats the way nature works. But engineers, climatologist, and with the plant scientists Agricultural Experiment Station at Utah State university have found a way to thwart nature and greatly reduce the chances of spring frost damage to the fruit crop. Under controlled research conditions, 27 days of bloom delay has been achieved. Regular overhead sprinkling irrigation systems have been adapted and used in some commercial orchard situations to achieve two weeks delay. A longer delay could be obtained by making sure to start early enough, as soon as temperatures start going above 45 When enough chill units have accumulated for the trees to complete their winters slumber, the researchers apply evaporative cooling using an overhead sprinkler. This prevents or slows down the radiant energy from the sun accumulating in the trees as it does naturally whenever the temperature rises above about 45 degrees F. and then sprinkle whenever the temperature is above that point, day or night. degrees, Not Too Long course you dont want to delay blossoming too long or your crop wont mature.

This concept, affecting the temperatures of the trees to alter development, is receiving notice worldwide. USU plant scientists have been invited to Europe to explain it there in international meetings. The research team members are being asked to explain the details of it at various meetings and research stations in the U.S. and Canada. the USU researchers have even been engaged to help set up a research Most interesting, project on peaches in Florida. Only there the problem is not frost, its insufficient winter rest. The aim is to hold the tree down through temperature evaporative colling so the trees will get a long enough period of winter rest, accumulating the necessary number of chill units to break dormancy. Through this modification of the trees natural slumber patterns, they expect to be able to produce some of the sweeter, more desirable varieties that presently will not bear truit in that climate.

FARR FENCING Now scientists are screening several hundred varieties to test their appeal to honey bees and their potential for higher yields through bee pollination. These results are expected to aid plant breeders in developing new varieties, and be of special help in programs that require use of hybridization. The process of hybridizing soybeans was recently made feasible by a team of scientists at North Carolinas Experiment Station. They discovered a male sterility characteristic in soybeans which they used to line. develop a male-sterilWithout the bees help, however, soybean hybridization requires tedious, expensive, and hand pollination.
