甘蓝型油菜‘南盐油1号’不同外植体再生体系的比较研究
The comparative study on different explant regeneration systems in canola‘ Nanyanyou 1' (Brassica napus L.)
摘要
Abstract
The plant tissue culture was tried in the experiment,in which hypocotyl and the cotyledon with petiole of 'Nanyanyou 1' ( Brassica napus L. ) were used as materials. The effects of cross combination of the different pre-culture and differentiation culture on the canola plant regeneration were studied. The results showed that different concentrations of 2,4-D,6-BA and AgNO3 had varing degree of influences on explant differentiation,however,differentiated buds were all able to take root and grow into plant. The differentiation rate of hypocotyl achieved the peak value(95.23% )in the pre-culture( MS+0.5 mg ? L-12,4-D+1.0 mg ? L-1 6-BA)and differentiation ( MS+3.0 mg ? L-1 6-BA+0.1 mg ? L-1 NAA+5.0 mg ? L-1 AgNO3);the cotyledon with petiole achieved the peak value (89.52%)in pre-culture(MS+0. 5 mg ? L-1 2,4-D+1.0 mg ? L-1 6-BA)and differentiation( MS+4.5 mg ? L-1 6-BA+0.1 mg ? L-1 NAA+5.0 mg ? L-1 AgNO3).To sum up,compared with the cotyledon with petiole,hypocotyl might be more suitable as the explant in tissue culture research of Nanyanyou 1'.关键词
