为加快社会主义林业建设步伐,实现毛主席“绿化祖国”的伟大号召,我场于1975年引用湿地松、火炬松、海岸松等国外松的花粉与油松、华山松进行杂交育种试验,收到了初步成效。现将杂交育种情况简介如下:一、花粉的索取及保存我们引用的湿地松、火炬松、海岸松等国外松的花粉,是1975年5月初由南京林产工业学院索取的当年新鲜花粉。花粉运到后,按品种装入玻璃试管内(装入的花粉量为试管容积的1/4),用脱脂棉堵塞封闭,放在冰箱2—4℃的温度下贮存。
In order to speed up the pace of socialist forestry construction and realize the great call of Chairman Mao to “green motherland,” I used the hybrid breeding test of pollen of Pinus tabulaeformis, Pinus taeda and Pinus taiwanensis and Pinus tabulaeformis and Pinus armandii in 1975 To the initial results. Brief introduction to the hybrid breeding now is as follows: I. Access to and preservation of pollen The foreign pollen from the pine, loblolly pine, and coastal pine, to which we quoted, was the pollen freshly collected by Nanjing Institute of Forestry and Industry in early May 1975. After the pollen has been transported to the glass tube, put the tube in a glass tube (the amount of pollen loaded is 1/4 of the tube volume), block it with clogs and store it in a refrigerator at a temperature of 2-4 ° C.
