Abstract:
Taking Sanqing asparagus lettuce variety ‘Tianxiangqing’ as the test materials,three factors method were used.The effects of gibberellin and water and nitrogen supply on the content of endogenous hormones such as gibberellin,auxin and cytokinin at the top of lettuce,stem cell length and lettuce growth index were studied,in order to provide reference for the scientific utilization of gibberellin and water and nitrogen supply.The results showed that water and nitrogen had a significant effect on lettuce plant height,shoot fresh weight,stem to leaf ratio,and stem diameter.Increasing water and nitrogen supply could significantly increase the above four indexes.In terms of quality,GA,water,and nitrogen had no significant effect on the chlorophyll content of Sanqing lettuce stems but had a significant effect on the cellulose content.GA treatment could reduce cellulose content,while decreasing water and nitrogen supply would increase cellulose content.In addition,after GA treatment,the GA,cytokinin (CTK),and auxin (IAA) contents in the lettuce top increased by 21.0%,53.6%,and 34.2%,respectively,compared with the control,while the abscisic acid (ABA) and jasmonic acid (JA) contents decreased by 14.8% and 31.7%,respectively,compared with the control.In summary,the length of epidermal and cortical cells in the stem increased significantly.Comprehensive analysis showed that GA mainly increased the endogenous GA,auxin,and cytokinin contents of Sanqing lettuce,promoting cell elongation,which ultimately led to an increase in plant height and leaf spacing;increasing water and nitrogen supply could improve the yield of Sanqing lettuce and reduce the cellulose content of the stem.
