1970年,美国学者一个惊人发现:从油菜花粉中提取到一种新的植物激素,可以使菜豆的生长率提高10倍! 1995年5月,两个中国人采用独创的“高效萃取法”,形成了规模的工厂化生产,使得芸苔素在农业上大面积应用成为现实。 难题的产生 美国学者米契尔坚信在花粉中会有高含量的植物激素,终于从油菜花粉中找到了它,当时只提取到10微克,同羊毛脂混匀涂于菜豆第二节间,4天后发现了奇迹。因为油菜属于十字花科的“芸苔属”,所以给这种激素命名为“芸苔素”(又称“油菜素内酯”),被列为第6类植物激素。同早期发现的5种生长调节剂进行对比,天然芸苔素用量极小而药效最高,因此被公认目前最好的植物生长调节剂。但是,目前国内外的天然芸苔素提取量仍然很小,而人工合成的成本也没有办法降下来。广泛应用的问题并没有得到解决。
In 1970, an astonishing discovery by American scholars: The extraction of a new plant hormone from rape pollen can increase the growth rate of kidney bean by 10 times. In May 1995, the two Chinese adopted the original “high-efficiency extraction method” The formation of a large-scale factory production, making the application of brassinol in a large area of agricultural reality. Difficult Problems American scholar Michele firmly believes that there will be a high content of plant hormones in the pollen, and finally found it from the rape pollen. At that time, only 10 micrograms were extracted, mixed with lanolin and applied to the second inbred bean, 4 Days after the discovery of a miracle. Because rape belongs to the cruciferous “Brassica”, this hormone is named “Brassin” (also known as “brassinosteroid”) and is classified as a Class 6 phytohormone. Compared with the five growth regulators discovered early, the natural amount of brassinilide is extremely small and has the highest potency. Therefore, it is recognized as the best plant growth regulator at present. However, at present, the extraction of natural brassinolide is still small at home and abroad, and the cost of artificial synthesis can not be reduced. Widely used problems have not been solved.
