2,4-D对石刁柏愈伤组织诱导的影响

Effect of 2,4-D on Callus Inducd in Asparagus officinalis L.

以石刁柏嫩茎为材料,研究了2,4-D对其初始愈伤组织诱导和胚性愈伤组织发生的影响。结果表明:仅仅只有2,4-D不能诱导石刁柏初始愈伤组织的发生;胚性愈伤组织的诱导需要高浓度的2,4-D,其最佳激素组合为2,4-D 10 mg/L+NAA 0.5 mg/L。

We studied effect of 2,4-D on initial callus inducing and embryogenic callus occurring from Asparagus tender stem culture, The results indicated callus was not induced if these was only 2,4-D in the medium. High concentration of 2,4-D in the medium was suitable for embryogenic callus occurring. The best hormone combination of embryogenic callus inducing was 2,4-D 10 mg/L＋ NAA 0.5 mg/L.
