Vedclass · Answer

(B) The primary reason for the failure of fruit formation in many cultivated rose varieties is that they are often 'double-flowered' cultivars. In these varieties,the stamens (male reproductive organs) have been evolutionarily or artificially modified into additional petals through selective breeding. Because the stamens are absent or non-functional,there is no production of pollen grains. Without pollen grains,pollination cannot occur,and consequently,fertilization does not take place. Since fruit formation is a post-fertilization event (where the ovary develops into a fruit),the absence of fertilization leads to the failure of fruit development.
