Orono Weekly Times, Wednesday, March 4th, 1981-7 VAN BELLË ON GARDENING GARDENING : . You asked for,it! Genetic engineering in science lecture All my bulbs are starting to , come up with this warm weather, what can we do, we are worried that they will freeze' when the weather Changes...I don't know if this weather is any indication that we are going to have an early spring, however, we are sure to get some cold weather yet, and the bulbs should be protected. Bulbs are usually planted 3 to 6 inches below the soil, so with the snow gone and this top layer free of frost the bulbs will automatically start to shoot. To hold them back a mulch of straw or peat or coca bean shells will keep frost in the ground, lowering the temperature of the, soil and stop the growing action of the bulbs. This must be done now to prevent damage to the tender tips of the bulbs. Rabbits have damaged my fruit trees by tearing off half of the bark, can we still save these trees? Yes,as long as you have at least some bark around the tree from the ground up to the top, enough sap will flow through the cambian layer to sustain the tree and the damaged part will slowly heal over. The area that has been damaged should be covered with a healing material such as Braco, this will keep out the weather and insects. Cut off any loose and frayed edges with a sharp knife, which will make it easier for the tree to heal over. Trees that have been completely girdled and have no bark where the cambian layer is located for the sap to come up, are hard to save since the tree will have no food for survival. One method of repairing this- damage is by bridge grafting a branch from the cambian layer at ground level to reach over the girdled part anti inserted into the cambian layer above the damaged area. Before starting this procedure ask an expert at your Garden Centre for the proper method and procedure. procedure. When should begonia bulbs be started? They should be started now, so that they will be ready to plant ih the spring. Plant them hollow side up, with the bulb almost left on the top of the soil. Plant them in a loose friable soil with plenty of peàt moss, water them sparingly for the first few weeks, and keep COMMITTEE to review PROPERTY STANDARDS BY-LAW (Continued from page 6) the conditions of the by-law. Counc. Taylor said the farming community was not opposed to the intent of the by-law but some amendments would have to be made to satisfy this community in the Town of Newcastle. The committee is to consider consider the documentation on them in full light with a temperature of no less then sixty degrees. Since begonias grow best in the shade they should have full light but never direct sunlight. An old trick to help prevent rotting of the bulb is to place a teaspoonful of sand just below the bulb. Begonia bulbs were discovered discovered by a monk called Charles Plumier, who was on a trip to the West Indies, where he found such beautiful vivid colored plants that he presented the begonia to the . Governor of the West Indies, whose name was Michael Begon, and baptized the name of the bulb Begonia in his honor. Two centuries later they found their way into England, whpre the Ghent or Belgian horticultuist Louis Van Houtte saw and imported them to Ghent Belgium, and to this day Ghent is still the worlds largest centre for .the propagation of Begonia Bulbs. Until next gardening. week, happy The concluding presentation presentation in the Durham Science Lecture Series features Dr. Eric James, Senior Research Scientist at Connaught Laboratories Laboratories in Toronto. His subject will be "Biomedical Technology - Genetic Engineering". Engineering". The talk will take place in Eastdale Auditorium in Oshawa at 8:00 p.m. on March 10th. In his talk, Eric James will outline the current incredible progress being made in his field, in particular, he" will discuss our new found ability to dissect the nucleic acid molecules comprising genes into unique small pieces. We are now able to clone any desired nucleic acid molecules, molecules, to determine their structure rapidly and then express the derived genetic information for production of large quantities of genetic products. , The current focus is directed directed towards the production of proteins, which are of immense immense importance to the health related field. With genetic engineering, society should be able to solve the potentially catastrophic problems problems of the 80's and beyond in regard to energy and food. Eric James has a distinguished distinguished background in research. research. Prior to his position as Senior Research Scientist at Connaught Laboratories, he was Associate Professor in the Department of Biochemistry Biochemistry at the University of Kentucky; also at the Department Department of Chemistry of the University of South Carolina. He was a Postdoctoral Research Research Fellow of the Harvard Medical School and is a graduate student in the Department Department of Biochemistry at Queen's University. He also taught at Cambrian College of Applied Arts and Technology. He has held several posts in industry, including Sales Manager for Union Carbide; Assistant Manager, Market Research and Development - U.S. Industrial Chemical Company; Development Engineer Engineer - Celanese Corporation and Sales Engineer for Shell Petroleum Company Limited.
