千分之一克分子浓度的乙烯利(二氯乙基磷酸)可以完全有效地诱发“NC—13”弗吉尼亚型和“斯塔尔”西班牙花生种子的发芽。处理将种子置于乙烯利水溶液湿润的纸巾内,一直放至见幼根开始长出时,然后转移到水湿纸巾内去长苗。要使刚收下的NC—13种子发出幼根,需要乙烯利处理3—4天,而贮藏过一个月的,一天的处理就够了。发出幼根后7—10天内全部种子长出正常幼苗。 将经过水湿巾吸涨10—14天而未曾发芽的斯塔尔和NC—13吸湿种子用乙烯利处理。1天处理的除了有4粒NC—13种子需另加2—7天处理外,全部开始发出幼根。所有经乙烯利处理的种子都开始发出幼根,并发育成为正常幼苗。 连续暴露于乙烯利内14天的幼苗,发育不正常。可推荐的方法是用乙烯利处理干的或吸涨的种子,直至见到幼根开始萌发时,然后将种子转移到水湿纸巾内去生长发育成苗。
One-thousandth of a gram of ethephon (dichloroethylphosphate) can be completely effective in inducing the germination of “NC-13” Virginia and “Starr” Spanish peanut seeds. Disposal Put the seeds in a damp tissue of ethephon and keep until the young roots begin to grow and then transfer to a damp tissue to transfer to the long seedlings. To seedlings of NC-13 seeds that have just been taken down, they need to be treated with ethephon for 3-4 days, and the one-month storage is enough to handle the day. 7-10 days after rooting, all seeds grow normal seedlings. Starches and NC-13 hygroscopic seeds which have not been germinated for 10-14 days after water wipes are imbibed with ethephon. All but one of the 4-day NC-13 seeds required an additional 2-7 days for treatment on one day. All ethephon-treated seeds begin to give off young roots and develop into normal seedlings. Continued exposure to ethephon 14 days of seedlings, dysplasia. The recommended method is to treat the dried or swollen seeds with ethephon until the young roots begin to germinate, and then the seeds are transferred to a water-wet tissue to grow and develop into seedlings.
