不同苗龄叶柄插接对西瓜嫁接苗生长发育的影响

试验对西瓜不同苗龄进行叶柄插接,通过对嫁接苗的成活率、株高、茎粗、地上部鲜重、地上部干重、地下部鲜重、地下部干重、叶面积、叶绿素含量的测定.结果表明:西瓜苗待子叶展平时;子叶展平,生长点稍有突起时;西瓜苗第一片真叶半展开时这3个时期进行西瓜叶柄插接比较适宜.

Effects of the Different Seedling Age in Watermelon with Petiole Insertion Grafting on the Growth and Development of Seeding

Studied the different seedling age of watermelon with petiole insertion grafting,through to measure living rate,plant height,stem diameter,upside fresh weight and dry weight,root fresh weight and dry weight,leaf area and chlorophyll content in watermelon seedling.The result showed that the period of unfolding cotyledon,the growth dot had a little salience when unfolding cotyledon period and the first true leaf had half unfolding that were three suitable periods of watermelon with petiole insertion grafting.
