【摘要】 本文报道了用化学药剂和植物生长调节剂处理（浸泡、喷雾、熏蒸）甘蔗种苗（Saccharum officinarum L.）对其萌芽及早期生长的影响。供试的22种药剂均能在一定程度上影响甘蔗萌芽和蔗苗生长,其中表现最好的7种药剂及其使用浓度是:0.01ppm（有效成分计,下同）油菜素内酯（BR）、50～900ppm乙烯利（CEPA）、2％熟石灰[Ca（OH）₂]、0.25％苛性钾（KOH）、200ppm黄腐酸（FA）、20ppm精氨酸（Arg）和1％硝酸钙〔Ca（No₃）₂〕。它们极显著（BR、CEPA,a=0.01）或显著[Ca（OH）₂、KoH,a=0.05〕及明显地提高了甘蔗出苗率并有利于蔗苗的早期生长,其作用特点各异。其中乙烯利处理,除显著促进萌芽和分蘖外,还可随处理浓度的增高而极显著地改变蔗苗形态。更多还原

【Abstract】 The effects of pre-soaking stock came with chemicals or plant growth regulators by soaking, spraying and fumigating on germination and early growth of sugarcane (Saccharum Officinarum L.) are reported in this paper. Theresuits indicated that all of examined 22 chemicals or growth regulators can improve germination and early growth of sugarcane, but it was different in degree and kind. The best sorts and applied doses among all chemicals or regulators were demonstrated respectively as follows: 0.01 ppm brassinosterods (BR), 50-100 ppm ethrel(2-chloroethyl phosphonic acid, CEPA), 2% slaked lime (Ca(OH)2), 0.25% KOH, 200 ppm fulvic acid(FA), 20 ppm arginine(Arg) and 1% Ca(NO3)2. In addition, if CEPA was sprayed or fumigated upon setts, the germination and tiller of sugarcane would increase significantly and the shoot morphology would have some obvious modifications.更多还原
