肌醇与硝酸银对霍霍巴多芽苗增殖的促进作用简报

Effects of inositol and silver nitrate on the shoots proliferation of Jojoba cultured in vitro.

试验研究结果表明在分化培养基中添加适当浓度的肌醇,有利于霍霍巴试管苗的生长和分化,其叶面积明显增大,芽分化率提高;1～3 5mg/ L浓度硝酸银对霍霍巴多芽增殖有显著促进作用,但对株高的影响不显著,且硝酸银浓度过高对试管苗有一定抑制作用,其最适宜浓度为3mg/ L。若二者同时添加效果更显著,其增殖系数可达10 9。

The Jojoba plantlets were in vitro treated by the subculture medium c on taining a suitable concentration of inositol and the result shows that it has a significant promotion to the shoots differentiation and leaf growth. 1 ～3 5mg/L of silve r nitrate significantly affects the shoots proliferation,but the plantl et height unremarkably. Exorbitant concentration of silver nitrate inhibits the plantlets growth in a certain extent,the best concentration is 3mg/ L. A very significant e ffect on shoots growth and proliferation can be attained by using 500m g/L of ino sitol together with 3mg/L of silver nitr ate and the proliferation coefficient is 10.9.
