材料和方法 采用生长健壮、树势中等的红星成龄树,亩产量3000斤左右。 为测定不同激素对整株上果柄或叶柄脱落的影响,在采前三星期(8月20日)对果实或叶片进行下列处理,每一处理3株,三次重复。 1—40ppm萘乙酸(NAA)加2000 ppm二甲基氨基琥珀酸(B_9);2—50ppm脱落酸(ABA);3—50ppm赤霉酸(GA_3);4—500ppm吲哚乙酸(IAA);5—500ppm乙烯利(Eth);6—对照,喷水。 整株树的果柄离区及成熟果外植体离区脱落测定,在采前落果开始,定树定枝定期观察果柄脱落。以离区有断痕,一触即落者表示脱落。定期按果柄外植体取样法,取下离区。
Materials and methods The growth of robust, tree-shaped Red Star adult tree, yield 3000 kg. In order to determine the effect of different hormones on the detachment of stalk or petioles, the following treatments were performed on the fruits or leaves for 3 weeks (August 20) three treatments each for three replicates. 1-40 ppm naphthaleneacetic acid (NAA) plus 2000 ppm dimethylaminosuccinic acid (B_9); 2-50 ppm abscisic acid (ABA); 3-50 ppm gibberellic acid (GA_3); 4-500 ppm indole acetic acid 5-500ppm Ethylene (Eth); 6-control, water spray. Whole fruit stalks from the region and mature fruit explants from the area off the determination, the beginning of the deciduous harvest, Ding Shu Ding regular observation of fruit stem off. To leave a mark from the area, one touch off that off. Regular fruit stem explants sampling method, removed from the area.
