采后果实失水萎蔫,甚至造成腐烂,这是鲜果流通、贮藏中存在的问题。国外试验证明,由于采后果实失水造成膨压增大,使呼吸加强,乙烯生成增多。因此认为水分胁迫造成果实的呼吸跃变与乙烯大量生成,而导致果实的成熟与衰老。但在教学实践中,往往缺乏对果实失水 After harvest fruit wilted water, and even cause decay, which is fresh fruit circulation, storage problems. Foreign tests show that due to post-harvest fruit dehydration caused by increased turgor pressure, so that breathing, ethylene production increased. Therefore, it is believed that the respiration of fruits caused by water stress and ethylene production are greatly increased, leading to fruit ripening and aging. However, in teaching practice, fruit dehydration is often lacking
