近20年来,为使某些作物便于进行杂交和获得杂交种子,不少国家研究了化学杀雄,以造成雄性不育。为避免柳絮的形成所造成的环境污染,我们用了两年时间,做了用化学药剂的氧化剂和还原剂处理早柳枝条控制雌雄花的研究,取得一定效果,现简报于后。一、材料和方法我们选用北京东北郊苗圃露地15年生的树高在10米左右,立地条件相同,生长势相近的雌雄旱柳各3株,再取其雌雄各2株作试验树,留下雌雄各1株作对照株。在每株供试
In the past 20 years, in order to facilitate the crossbreeding of some crops and obtain hybrid seeds, many countries have studied chemical killing male to cause male infertility. In order to avoid catastrophe caused by the formation of environmental pollution, we spent two years, made with chemicals oxidant and reducing agent treatment of early willow branches of male and female flowers, and achieved some results, is now reported later. First, materials and methods We choose Beijing northeast nursery nursery open-field 15-year-old tree height of about 10 meters, the same site conditions, growth potential similar to the male and female three willow trees, and then take the male and female each two for the test tree, leaving One male and one female as the control strain. Test in each plant
