关于锦葵科植物通过花药培养获得花粉植株,国内外尚少报道。红麻属锦葵科植物,为探索红麻育种新途径,加快育种步伐,从1979年开始进行红麻花药培养的研究。 取花粉为单核靠边期,大小为0.8~1.0厘米的花蕾,按常规方法消毒后在无菌条件下接种于培养基上。试验结果表明:红麻花药的培养须经过愈伤组织诱导、增殖分化、再诱导、 About Malvaceae plants obtained by anther culture pollen plants, is still rarely reported at home and abroad. In order to explore new ways of kenaf breeding and speed up the breeding process, the kenaf genus Malvaceae was studied. Take the pollen as the mononuclear margin, the size of 0.8 to 1.0 cm flower buds, according to the conventional method of disinfection inoculation on the medium under sterile conditions. The results showed that the kenaf must be callus induction, proliferation and differentiation, re-induction,
