Abstract

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
