铁皮石斛种胚萌发和原球茎质量控制

Germination of dendrobium candidum embryos and quality control of protocorm-like bodies

本文讨论了植物生长素对铁皮石斛种胚萌发和 ABA对原球茎质量的影响 .实验结果表明 NAA在 0 .0 5～ 2 .0× 10 -6范围内都能促进种胚萌发 ,而 2 ,4 - D促进种胚萌发的浓度范围很窄 ,仅在浓度为0 .5× 10 -6时能促进种胚萌发 ;0 .5× 10

Both the effects of auxin on D. \$candidum\$ embryos germination and of ABA on PLBs quality were described.Experimental results showed that the range of 2,4\|D concentration capable of stimulating embryo germination was quite narrow,to be about 0.5×10\+\{-6\} only.For NAA,the effective range was 0.05×10\+\{-6\}～2.0×10\+\{-6\}.That 0.5×10\+\{-6\} ABA could significantly activate the growth of PLBs were found and their quality was improved.
