芝麻下胚轴愈伤组织的形成和器官发生

Callus Induction and Organogenesis of Sesamum indicum L.Hypocotyl

本文研究了五种植物激素对芝麻下胚轴愈伤组织的形成和器官发生的影响．研究表明：（１）２．４－Ｄ或ＮＡＡ（１ｍｇ／Ｌ）＋ＢＡ或ＫＴ（０．ｓｍｇ／Ｌ），２．４－Ｄ（０．５－１ｍｇ／Ｌ）和ＮＡＡ（０５－１ｍｇ／Ｌ）对愈伤组织的诱导率最高；（２）ＢＡ或ＫＴ（０．５－１ｍｇ／Ｌ）可促进下胚轴芽丛的形成（３）ＮＡＡ（０．５－１ｍｇ／Ｌ）、ＩＡＡ（０．５－１ｍｇ／Ｌ）和ＫＴ（０．５－１ｍｇ／Ｌ）对下胚轴根的形成最有利．

This paper deals with the studies on Callus initiation and organogenesis of thehypocotyl of Sesamum indicum L.in differential plant hormones and concentration.Results show:(1) 2,4-DorNAA(1mg / L)+BAor KT (0.5mg / ).2,4-D(0.5-1mg/ L) and NAA(0.5- 1mg / L)have good effect on the induction of Callus; (2) BA(0.5-1mg/ L)and KT (0.5-1mg/ L) can promote the formation of buds;(3)NAA(0.5- 1mg / L). IAA(0.5- 1mg / L)and KT(0.5- 1mg / L) are beneficial in the formation of the roots.
