摘要: 为探究赤霉素对珠芽魔芋种子萌发的影响,本文以珠芽魔芋种子为材料,将种子用不同浓度梯度的赤霉素溶液进行处理,以便分析赤霉素对珠芽魔芋种子萌发的影响以及萌发期间种子内含物的变化。结果表明,种子经50 mg/L赤霉素处理后,萌发率达到最大,由72%提高到98%;在种子萌发过程中,对照组魔芋种子芽长从0.4 cm生长到1.6 cm时,可溶性糖含量从7.633 mg/g增加到9.551 mg/g;可溶性蛋白从9.668 mg/g增加到10.408 mg/g;经50 mg/L赤霉素处理的试验组种子芽长从0.4 cm生长到1.6 cm时,可溶性糖含量从7.798 mg/g增加到10.153 mg/g;可溶性蛋白从9.611 mg/g增加到10.441 mg/g,试验组的增幅较大,表明赤霉素能促进种子内有机物质的分解,从而促进种子萌发。

Abstract: To explore the effect of gibberellin on seeds germination in A. Bulbifer, the seeds were treated by using different concentration gradients of gibberellin. Additionally, seed germination percentage and biochemical change were analyzed during the germination. The results showed that the percentage of seed germination was increased from 72% to 98% under the treatment of 50 mg/L gibberellin. During seed germination, in the control group, the length of hypocotyl increased from 0.4 cm to 1.6 cm, the soluble sugar content increased from 7.633 mg/g to 9.551 mg/g and soluble proteins increased from 9.668 mg/g to 10.408 mg/ g; in the test group, the length of hypocotyl increased from 0.4 cm to 1.6 cm, soluble sugar content increased from 7.798 mg/g to 10.153 mg/g and soluble proteins increased from 9.611 mg/g to 10.441 mg/g. The results suggested that gibberellin could increase the decomposition of organic material in the seed, which could promote seed germination.
