第二次世界大战的前二年,纽约省长岛地方卡纳淇研究院有两位科学家,一位叫爱阜连A.G.Avery,另一位名叫勃莱克斯利A.F.Blakeslee,他们在日常生物研究工作之外,偶而做一些带着几分余兴性质的试验。有一次他们把秋水仙碱Colchicine 融解水中,再把几样植物的种籽浸在液中。时间有长有短,经过浸润以后把种籽放在土中。数星期之后长成的植物比寻常所见者加倍的大。这两位先生大为惊奇。他们便把这植物的组织在显微镜下细加察看,发现植物的
In the first two years of World War II, there were two scientists at the Canakkis Research Institute in Long Island, New York. One was Evergreen AFA and the other was AFBlakeslee, Outside the work, occasionally do some experiments with somewhat of a delightful character. Once they had colchicine colchicine dissolved in water, and then a few samples of plant seeds immersed in the liquid. The time is long and short, after infiltration of seeds on the soil. The plants that grow into in a few weeks double the size of those seen by others. The two gentlemen were greatly surprised. They took a closer look under the microscope of the plant’s tissue and found the plant’s
