浙江红花油茶是我省800米以上山地的主要木本油料树种。抗寒性强,出油率较高,但产量低、果皮厚,出籽率低。为了培育高产、优质的新品种,我们在一九七四年进行了辐射育种试验,现将粗浅的体会作一介绍。 浙江红花油茶花期为二至四月。我们于四月一日采集已开放的茶花花药,放在室内阴干散粉。花粉装在指形管内,用Co~(60)-γ射线照射,四月十日照射完毕。处理剂量分 Zhejiang safflower Camellia is the province of 800 meters above the mountain woody oil tree species. Cold hardiness, high oil yield, but low yield, thick pericarp, low seed yield. In order to cultivate new varieties with high yield and good quality, we conducted a radiation breeding experiment in 1974, and now we introduce the superficial experience. Zhejiang safflower flowering from February to April. We collected the open camellia anthers on April 1 and left indoors with loose powder. Pollen in the finger tube, with Co ~ (60) -Gamma irradiation, April 10 irradiation is completed. Processing dose points
