【Abstract】 The yield of root tubers and its starch contents were increased 10% and 11～29% respectively,when the cassava plants were spraied or smeared with ethephon at middle and late growth stage.The photosynthetic rate, content of reducing sugar and the activities of neutral and acid sucrase in leaf are all greater than that used no ethephon.更多还原
