Flowering in Lemna perpusilla 6746 grown on tenth-strength Hutner's medium under short days was inhibited by 30 mM sucrose, glucose or fructose, but not by mannitol. The inhibition by sucrose does not appear to be due to sucrose-induced acidification of the medium during growth, or to trace metal contaminants of the sugar. Inhibition was partially prevented by raising either Ca(2+) or phosphate to levels used in half-strength medium. Possible mechanisms for these effects are discussed.
在短日照条件下,生长在第十倍强度 Hutner 培养基上的小浮萍 6746 的开花受到 30mM 蔗糖、葡萄糖或果糖的抑制,但甘露糖醇没有抑制作用。蔗糖的抑制作用似乎不是由于生长过程中蔗糖诱导培养基酸化,也不是由于糖中的痕量金属污染物。通过将 Ca(2+)或磷酸盐提高到半强度培养基中使用的水平,可以部分防止抑制。讨论了这些影响的可能机制。
