アルファルファに於けるトリッピングの授精に及ぼす影響について

抄録

The present paper reports on the effect of tripping on seed production in alfalfa whose seed production is generally difficult in this country. It is considered from the data obtained that the flowering behavior which has the most important role in the fertilization throughout the whole period of tiowering is the colliding of stigma with standard petal soon after tripping rather than at time of the tripping, because the colliding seems to scatter the pollen grains caught by tripping as a mass on the stigmatic membrane which presumably furnishes the most suitable bed for their germination, to bury them in it, and to expose the conductive tissue in the style by transformation of the stigmatic tissue. It is a problem yet to be solved that whether this transformation of stigmatic tissue results in effective penetration of pollen tube into style or not. (Received April. 4, 1954)
