我們曾以不同浓度的赤霉素处理黄麻种子和噴射麻株,並观測其促进黄麻生長和增加麻皮产量的效应。試驗主要結果如下: 1.赤霉素处理种子的效应:赤霉素处理黄麻种子,有促进种子萌发、提高出苗率和加快幼苗生長的作用。尤其对于在本省气候条件下出苗率低、出苗持續时間長的長果种黄麻,其效果更为显著。根据試驗,种子以1～5ppm赤霉酸处理的效果最好,发芽势,圓果种較对照增加4％,長果种較对照增加29％;出苗率,圓果种較对照提高9％,長果种較对照提高17～28％;原麻产量較对照增产3.47～4.5％,其中以5 ppm处理的效果最高。赤霉素处理种子,对地上部分有加速伸長的作用,因此有利于麻皮的增产。但在另一方面,也可看出种子經处理后,其植株常有“缺綠”現象,色泽較淡。
We treated jute seeds with different concentrations of gibberellin and sprayed the hemp plants, and observed their effects on promoting jute growth and increasing the yield of hemp. The main results of the experiment are as follows: 1. Effects of gibberellic acid treatment of seeds: GA treatment of jute seeds can promote seed germination, increase germination rate and accelerate seedling growth. Especially for the jaundice species with low emergence rate and long duration of emergence under the climatic conditions of this province, the effect is even more remarkable. According to the experiment, the seeds treated with 1 ~ 5 ppm gibberellic acid had the best effect. The germination potentials of the seeds were 4% higher than the control and 29% higher than the control. The germination rate and the round fruit were increased by 9% The fruit variety increased 17-28% compared with the control. The yield of the raw maize increased 3.47-4.5% compared with the control. Among them, the effect was highest at 5 ppm. Gibberellin treatment of seeds, to accelerate the elongation of the role of the ground, it is conducive to the production of hemp bark. However, on the other hand, we can also see that after the seeds are treated, the plants often have the phenomenon of “lack of green” and the color is lighter.
