Such an imbalance is probably due to a great increase of entry of Na^+ ions into cells and a decline in absorption of K^+ ions under high-salinity conditions. Thus, plant cells展开更多

文摘花叶芋(Calalium bicolor),又名五彩芋,属天南星科,是一种美丽的观叶植物,原是通过块茎繁殖,但其休眠期长,增殖速度慢,因此,利用组培扩大繁殖,以满足市场需要。关于花叶芋的组培,已有不少报道,但对合适的培养基的筛选,分化的途径都还有研究的必要。为此,我们以花叶芋叶柄、叶片为材料进行了初步研究现结果如下:1.愈伤组织的诱导和培养基的改进:所用培养基中在 MS 附加2,4-D1ppm,KT 1ppm、
