西瓜种籽常因制种技术上的问题以及贮藏时间过久等原因,使发芽率明显下降,出苗率低,幼苗生长衰弱,造成播种后缺苗,植株间参差不一,对西瓜生产影响甚大。前人曾利用赤霉素、萘乙酸等化学物质处理种籽,虽有效果,但胚根或胚轴变短,幼苗生长细弱,活力指数低,在生产中没有采用。为了获得更好的效果,本试验使用新近出产 Watermelon seeds often due to seed production technology and storage time is too long and other reasons, so that the germination rate decreased significantly, the emergence rate is low, seedling growth is weak, resulting in lack of seedlings after sowing, plants vary greatly, have a great impact on watermelon production . Previously, the use of gibberellin, naphthalene acetic acid and other chemicals to deal with the seeds, although the effect, but radicle or hypocotyl shortening, seedling growth is weak, low activity index, not used in the production. In order to get better results, this test uses the latest production
