矮牵牛花器官突变体blind-like的表型和解剖结构

 从矮牵牛自交系中获得一个花器官变异突变体, 将其命名为blind-like。该突变体的性状能够稳定遗传, 主要表现为花数增多, 花瓣顶端出现花药状结构, 具有类似正常花药的四分室结构, 并产生少量花粉。该突变体与矮牵牛花器官blind突变体相似, 通过自花授粉与异花授粉产生种子。

Morphological Characteristics and Anatomy of a Novel Floral Mutant of Petunia

A spontaneously occurred floral mutant with multi-flower and exhibiting antheroid structure on the top of petals was found in the progeny of a instable self-line of petunia. The anther of the mutant has a resembled structure in normal plants and can produce a little infertile pollen in it. The mutants could produce seeds by self-pollinated or pollinated with pollens from the wild type. The similarity and differences of blind-like with similar petunia mutants was discussed.
