摘  要：
以茄子单性结实品系D-10和D-21及非单性结实品系03-2为试材,研究在自然低温条件下自然授粉、人工授粉和去柱头后茄子果实发育过程中内源激素生长素(IAA)、赤霉素(GA4)、玉米素核苷(ZR)和脱落酸(ABA)含量的变化及与单性结实果实发育的关系.结果表明:3种授粉方式下单性结实品系果实都可以正常膨大,而非单性结实品系果实只在人工授粉的情况下正常发育.单性结实品系果实发育前期的IAA、ABA含量和ABA/(IAA+GA4+ZR)均高于非单性结实品系03-2;茄子3个品系子房(果实)发育前期的IAA、ZR含量明显高于果实发育后期的IAA、ZR含量.不同品系不同授粉方式下果实发育过程中GA4含量变化无明显的规律性.人工授粉提高了03-2果实发育初期的IAA、GA4和ABA含量,对ZR含量和ABA/(IAA+GA4+ZR)无明显影响,但促进了其果实的发育.自然授粉和人工授粉下03-2果实发育过程中ABA含量和ABA/(IAA+GA4+ZR)一直维持在较低水平.果实发育初期较高的IAA和ABA水平有利于茄子果实发育和单性结实.

摘  要：
The eggplant(Solanum melongena L.)parthenocarpic lines D-10,D-21 and non-parthenocarpic line 03-2 were taken as materials,the relationship between the change of endogenous hormones(IAA,GA_4,ZR,ABA) contents during fruit developmemt and the fruit size were studied under natural low temperature by using natural pollination,artificial pollination and removing stigmas methods.The results showed that the fruit of parthenocarpic lines(D-10 and D-21) grew normally under three pollination methods and non-parthenocarpic line(03-2) were only in the condition of artificial pollination.In the early fruit development of eggplant,the contents of IAA,ABA and ABA/(IAA+GA_4+ZR) in parthenocarpic lines were higher than 03-2.The contents of IAA and ZA in ovary(fruit) during pre-fruit development were higher than later fruit developmet in parthenocarpic lines and non-parthenocarpic line.There was no obvious regularity in the change of GA_4 content in parthenocarpic lines and non-parthenocarpic line with three pollination methods.In the early fruit development,the contents of IAA,GA_4 and ABA were improved by artificial pollination in non-parthenocarpic line 03-2 which were benefit for fruit development,while the contents of ZR and ABA/(IAA+GA_4+ZR) were not effect.The contents of ABA and ABA/(IAA+GA_4+ZR) were lower in non-parthenocarpic line 03-2 during fruit development by using natural pollination,artificial pollination.The high contents of IAA and ABA were benefit to fruit development and seedless during early fruit development.
