摘要
为解决生产中西瓜膨大期易遭受涝害胁迫问题,以盐城地区主栽的西瓜品种为材料,在涝害胁迫下,通过喷洒8种药剂缓解涝害胁迫,比较不同药剂对西瓜的产量、品质和生理指标的影响。结果表明,在单果重和产量方面快生的恢复效果最好,差异均达显著,分别增加了27.22%和27.31%。基因活化剂、爱多收、细胞分裂素等外援药剂在一定程度上可有效缓解涝害胁迫对西瓜的伤害,抑制叶片MDA产生(爱多收效果最显著,降低了54.01%),提升PAL活性(细胞分裂素效果最佳,提升了72.22%),增强根系活力(基因活化剂效果最好,增加485.16%),使植株维持良好的吸收水分和养分的能力。
The paper aims to solve the problem that watermelons are vulnerable to waterlogging stress at the swelling stage in production. The watermelon cultivar planted in Yancheng was used as the material, 8 kinds of medicaments were spayed to alleviate the damage of watermelon under waterlogging stress, and their effects on the yield, quality and physiological indexes of watermelons were compared. The results showed that rapid growth had the best recovery effect in terms of single fruit weight and yield, with significant increase of 27.22%and 27.31%, respectively. To a certain extent, foliar-spayed medicaments such as gene activator, epiglottifolin and cytokinin could effectively alleviate the damage of waterlogging stress on watermelon, inhibit MDA production in leaves(the most significant reducing effect was achieved by epiglottifolin as 54.01%), enhance PAL activity(the best increasing effect was achieved by cytokinin as 72.22%) and root vitality(the best increasing effect was achieved by gene activator as 485.16%), and maintain the plant’s ability to absorb water and nutrients well.
