Abstract:

本文采用不同浓度的2,4-表油菜素内酯(EBR)处理不同发育阶段的网纹甜瓜植株,观察EBR处理植株和对照植株的光合相关指标的变化,分析收获后EBR处理和对照植株之间果实品质的差异.结果表明,提高网纹甜瓜光合速率的最有效的EBR浓度是0.1mg·L-1.在幼苗期和初花期植株中,EBR处理改善了净光合速率(Pn)和气孔导度(Gs),同时降低了胞间CO2浓度(Ci)和蒸腾速率(Tr),而EBR对光合速率的改善是由于非气孔因素所致.在结果后期,EBR处理植株的Pn、Gs和Ci均高于对照植株,而Tr则低于对照;EBR处理植株的光合能力的上升是由于气孔因素所致.EBR可以有效地提高果实的纵径和横径,显著提高果实重量;EBR促进果实和重量增大的原因可能是EBR直接促进了细胞的生长和分裂.此外,EBR处理植株果实的可溶性固形物含量也出现显著地提高.根据上述结果推测EBR能提高网纹甜瓜植株的光合速率,促进碳水化合物从叶片向果实的转运.本研究有助于进一步探究BR类物质对甜瓜植株光合作用以及果实品质影响的作用机理,同时也为网纹甜瓜优质高产栽培提供理论依据和方法指导.
