作者于1957年选取红色火焰品种——Zinnia——elegans,Variety,Scavlet的同等大小幼苗,栽入2.5吋的缽内。所有幼苗节间长度不超过0.1厘米,第一对真叶长度不超过0.3厘米,试验分9组进行。每五株植物一组,每组分别以0.0001,0.001,0.01,0.1,1.0,10,100,1000,和10000P.P.M赤霉素喷射,另一组作对照,并每天夜间分别给予10℃,12.8℃,15.5℃,18.3℃,21.1℃的温度。每种温度有四个重复,给每种温度中的两个重复以300支光光照16小时和强烈日光8小时;另外两个重复给予16小时黑暗和8小时强列日光。
In 1957, the author selected the same size seedlings of the red flame species - Zinnia - elegans, Variety, Scavlet and placed them in a 2.5 "pot. All internode length of no more than 0.1 cm, the first pair of true leaves no more than 0.3 cm in length, the test points were carried out in 9 groups. Each group of five plants were injected with 0.0001, 0.001, 0.01, 0.1, 1.0, 10, 100, 1000, and 10,000 P.PM gibberellin respectively, and the other group served as control and were given 10 ℃, 12.8 ℃ , 15.5 ° C, 18.3 ° C, 21.1 ° C. Four replications for each temperature, 300 light exposures for 16 hours and intense daylight for two of each of the temperatures were repeated for 8 hours; the other two were given 16 hours of darkness and 8 hours of intense sunlight.
