描述了芭蕉属(芭蕉科)一新变种——雷波野芭蕉(Musa luteola J.L.Liu var.leiboensis J.L.Liu et Q.Luo),并绘制了形态图。新变种以其叶基部渐狭至楔形,叶柄和叶鞘两侧具纸质或干膜质的翅,花序下垂,椭圆形或卵状椭圆形,先端圆,苞片外面淡黄色或绿黄色,先端圆或钝圆,每苞片内有花二列,果序球状、近球状或椭圆状球形,果实密集与黄色野芭蕉(Musa luteola J.L.Liu)相近似,但主要又以子房具5～9钝状棱角,浆果较大,长(6.7～)8.5～11.9 cm,宽5～7.2 cm,具5～9钝状棱角,果梗较长1～1.5 cm而有显著区别。 相似文献

Plants have been regenerated from anthers of Primula obconica frozen in liquid nitrogen for 5 minutes, and cultured on synthetic media. There were two modes of plant development, directly from pollen-embryos, and indirectly through the differentiation of callus. 相似文献

SummaryShoot tips established in vitro better than single nodes. Five-cm shoot tips gave better Stage I results than 2-cm shoot tips. The best microshoot proliferation rates were obtained with isopentenyladenine (2iP) at 5 and 10 mg l?1; tetrahydropyranyl-benzyladenine was ineffective. Microshoots rooted well, regardless of the level of 2iP in the Stage II medium. Stem-cutting-macropropagated plants generally were more variable in height, had less basal branching and were more erect than plants from microculture. 相似文献
