Abstract It is generally agreed that many Vitis vinifera L. cultivars are self-fertile, where self-pollination often occurs before
capfall in a process called cleistogamy. Therefore, it is difficult to identify the right time to remove stamens before
self-pollination during the cross-breeding of grape. For this paper, we observed the process of grape flowering and
measured the pollen viability and stigma receptivity of grape flowers of ‘Shine Muscat’ in order to identify the
starting time of self-pollination before capfall and to provide useful information for improving the efficiency
of cross-breeding. The results demonstrate that the anther is not cracked during the visible… More >
