摘要：

为探究不同浓度的外源物质脱落酸(ABA)对小豆农艺性状及产量的影响,以2个小豆品种‘白红8号’和‘012-27’为试验材料,大田花期叶面喷施后,在不同生育期测量植株主茎长度、主茎粗度、叶片鲜重、根系鲜重及产量性状等。结果表明：花期施用浓度为100 mg/L和200 mg/L的ABA能显著降低‘白红8号’和‘012-27’的主茎长度。2个品种不同浓度处理与CK相比茎粗均显著增加。‘白红8号’和‘012-27’在处理A100中开花期叶片鲜重分别比CK增加了33.54%、23.81%。2个小豆品种A100处理的单株粒数与CK相比分别增加了12.80%、20.13%。综上所述,喷施脱落酸能降低小豆植株的主茎长度,显著增加主茎粗度、叶片鲜重、根系鲜重及小豆单株粒数,小豆花期喷施浓度为100 mg/L的ABA可在一定程度上提高产量。

Abstract:

To explore the effect of different concentrations of exogenous substances abscisic acid (ABA) on the agronomic characters and yield of adzuki bean, adzuki bean variety ‘Baihong 8’ and ‘012-27’ were used as the experimental materials. After spraying different concentrations of ABA on the leaves in field, the length of the main stem, the diameter of the main stem, the fresh weight of the leaves, the fresh weight of the roots and the yield characters were measured at different growth stages. The results showed that ABA treatment with 100 mg/L and 200 mg/L at flowering stage could significantly reduce the main stem length of ‘Baihong 8’ and ‘012-27’. In the treatment of A100, the fresh weight of leaves of ‘Baihong 8’ and ‘012-27’ at flowering stage was increased by 33.54% and 23.81%, respectively. Compared with that of CK, grain number per plant of the two varieties under A100 was increased by 12.80% and 20.13%, respectively. To sum up, abscisic acid spraying could reduce the length of main stem of adzuki bean, and increase the diameter of main stem, fresh weight of leaves, fresh weight of roots and the number of seeds per plant of adzuki bean significantly. ABA spraying of 100 mg/L at flowering stage could increase the yield of adzuki bean to some extent.
