Gibberellic acid對赤豆之蒸散作用及其他幾種反應之效果

Transpiration and some other responses of Adzuki bean (Phaseolus sp.) to gibberellic acid

The gibberellins are well recognized as being able to regulate the growth and development of a great variety of plants. Some responses of Adzuki (Azuki) beans to these substances were reported by Shimada and recently by Chiang and Chiang. It was suggested by Chiang and Chiang that the acceleration of the conduction of water and translocation of other substances from the root to the shoot occurred in gibberellic acid (GA)-treated Adzuki beans because the formation of secondary xylem was greatly stimulated. The effect of GA on transpiration rate of this plant was, therefore, investigated. More recently Linck and Sudia reported that GA accelerated the absorption and translocation of phosphorus-32 in bean plants (Phaseolus vulgaris).
