俄罗斯科学家在太空失重条件下种植和 收获小麦的试验已经获得成功。据俄罗斯医学 生物学研究所的专家介绍,在太空失重条件下 种植小麦的试验已有多年。开始时,播种在宇 宙温室里的小麦能够发芽,但是不抽穗。后经研 究查明,影响麦于生长的是有机化合物乙烯,乙 烯是一种有甜香气味的无色可燃气体,麦子自身、太空舱里的器械和聚合物都会产生乙烯,乙烯对麦子而言是效力极强的“避孕剂”。由于乙烯的作用,在太空首次试验种植的名为“超矮人”的小麦品种没有留下后代。 Russian scientists have succeeded in planting and harvesting wheat under conditions of weightlessness in space. According to experts from the Russian Institute of Medical Biology, experiments have been carried out on wheat under space-weightless conditions for many years. Initially, the wheat sown in the greenhouse of the universe germinated, but not heading. After the study found that the impact of wheat in the growth of organic compounds of ethylene, ethylene is a colorless and flammable gas with a sweet smell, the wheat itself, spacecraft equipment and polymers will produce ethylene, ethylene to wheat Is highly effective “contraceptives.” Due to the effect of ethylene, the wheat varieties “Ultra Dwarf” planted in space for the first time did not leave offspring.
