Studies on flower bud formation of asparagus officinalis l

Studies on flower bud formation of asparagus officinalis l

Journal of the Faculty of Agriculture Hokkaido University 64(4): 272-278

Histological observation of the flower bud formation process in asparagus (Asparagus officinalis L.) was carried out microscopically. Developmental process of the flower bud formation were classified into 5 stages: domed primordium stage, outer tepal-forming stage, inner tepal-forming stage, pistil-forming stage and flower bud-developing stage. Before pistil-forming stage, no morphological difference in flower bud structure existed between male and female flowers. Flower bud formation started approximately at the time of the onset of lateral shoot primordium formation, and subsequently was synchronized. The number of flower buds in one spear of a male plant was more than that of the female. It is already known that total number of flowers per adult stalk in the male plant is more than that in the female. From the results of the present research, the difference was recognized between the younger spears (less than 10 cm in length) of the male and female. On a spear before flowering, flower bud growth index in the male plant was a little higher than that in the female. Further researches on the scatter of the flower bud growth index per spear in the male plant and the female plant should be attempted. It was clarified that the differentiation of flower buds did not occur before the growth onset of the bud on rhizome, but began at the same time of the bud growth onset and was gradually synchronized. It is suggested that the flower buds in the spear bud (especially in spear) that has stopped its growth before winter may overwinter and start to grow in the next season.
