甘蓝型油菜新不育系恢复材料花药培养影响因素的研究（英文）

Some influential factors of anther culture were studied preliminarily by conducting anther culture of the restorers of new cytoplasmic male sterile(NER).Several results were obtain from this experiment and they were listed as follow:① MS cultrure medium with such hormones as 2,4-D 2 mg/L,6-BA 0.5 mg/L,NAA 0.5 mg/L was the best suitable for callus induction of NER.②The difference of induction rate was significantly different between different plant age groups.From the 110th day to 141th day,the induction rate was increased with the increase of age and the difference of induction rate reached 0.01 significant difference level.The induction rate reached the highest value in the 141th day then it declined gradually.③The combined use of 2,4-D and 6-BA with proper increase of 2,4-D was good for inducing callus.④The green plantlet induction rate of NER was increased when the concentration of 6-BA increased from 2 mg/L to 4 mg/L.Adding ZT from 0.5 mg/L to 2 mg/L,6-BA would led 2.47% increase of green plantlet induction rate.
