这是一份只有标题的记录，没有摘要。所研究的无花突变体是从X射线照射的番茄品种康丁红的种子中获得的。在正常番茄植株和突变体anantha中分别导致形成二歧聚伞花序和蝎尾状聚伞花序的阶段I和II的研究表明，在后一种情况下，不仅阶段I的持续时间比正常植株更长，而且分枝的数量也更大，伴随着原基的缺乏和位于中央的花在二歧聚伞花序中的发育。同样在突变体中，通常导致个体花发育的阶段II在持续时间和产生的蝎尾状聚伞花序的数量方面受到限制。没有原基或花的分化，这两个阶段之间的平衡改变，由于花序轴的多样性，整个花序增大，完全没有原基和花的发育，因此植株不育。
This is a title only record which contains no abstract.The anantha mutant investigated was obtained from X-irradiated seed of the tomato variety Condine Red. Study of the phases I and II which result in the formation of the dichasia and scorpioid cymes respectively, in the normal tomato plant and the mutant anantha showed that in the latter case not only is phase I of longer duration than in the normal plant but also the number of branchings is greater, with a concomitant absence of primordia and of development of centrally situated flowers in the dichasia. Again in the mutant, phase II, which normally leads to the development of the individual flowers, is limited as regards duration and the number of scorpioid cymes produced. No primordia or differentiation of flowers is found. Alteration of the balance between the two phases causes enlargement of the whole inflorescence owing to the multiplicity of inflorescence axes and complete absence of primordia and flower development, so that the plant is sterile.
