Studies on flowering order of the sesame plant

Abstract

(1) The author examined the flowering order of the sesame, dividing the flowers, by there position, in two sorts of the chief flowers and the side flowers. (2) The difference in the days of flower opening between node to node was on average about one day in the chief flowers, advancing from the bottom to the upper part almost straightly. (3) Many aborted were found in the chief flower groups at the bottom of stem, while in the side flowers they located at various positions. (4) The percentage of fruit-setting was rather low at the lower flowers, highest at the middle and suddenly decreased at higher part. (5) The side flowers were observed less than the chief flowers both in the percentages of flower-setting as well as of fruit-setting. (6) The length of pods was short at the bottom, increasing toward the middle part, but gradually lessened from the middle to the high, showing a sudden decrease at the top, while in thickness and breadth they were smaller at the low to the middle parts and then gradually decreased upwards. (7) The grains in a pod were rather few in number at the low part, largest at the middle and a few at the high part. (8) The dried grain weight was heavy at the low part, while lather light at the middle, and the lightest at the high part.
