摘要: 以番茄接穗品种(中杂105号、中杂109号、硬粉8号)和砧木品种(重庆番茄砧、桂砧1号、桂TA06)为试材,研究施肥量和烯效唑对番茄幼苗下胚轴长度、直径及相关生理指标的影响,提出优化番茄嫁接穗/砧胚轴生长的肥料和烯效唑复合施用技术。结果表明:增量施肥后,番茄穗/砧幼苗下胚轴伸长生长迅速,上胚轴较长,下胚轴干物质积累、含水量及伤流液质量增加,木质素含量降低;烯效唑抑制了番茄穗/砧幼苗上胚轴的伸长生长,抑制幼苗徒长,促进了下胚轴干物质的积累,木质素含量及花色素苷含量的增加。说明施肥与生长抑制剂复合施用,可以有效调节番茄穗/砧下胚轴的生长发育。

Abstract: Tomato scions(Zhongza 105,Zhongza 109,Yingfen 8)and rootstocks(Chongqing TR,Guizhen 1,GuiTA 06)as the materials,the physiological and morphological indexes of tomato hypocotyl were investigated after fertilization and uniconazole.Propose technology of fertilization and uniconazole composited application to optimize growth of tomato scions and rootstocks in grafting.The results showed that fertilizer treatment can improve tomato hypocotyl and epicotyl length and weight,and reduce the lignin content;Uniconazole spraying treatment inhibits epicotyl length and strench,and promote dry weight,the lignin content and anthocyanin of hypocotyl.Fertilization and uniconazole can effectively regulate the growth and development of tomato hypocotyls.

Key words: Tomato, Hypocotyl, Fertilization, Uniconazole, Growth and development
