Studies on the cutting propagation of Taxus chinensis var.mairei.Ⅲ .Effects of foliage fertilizer and transparency on growth of the cut seedlings
南方红豆杉扦插繁殖技术研究——Ⅲ.叶面肥与透光度对扦插苗生长的影响

Effects of foliage fertilizer and transparency on the growth of the cutting of Taxus chinensis var.mairei were studied.The results show that the effects of foliage fertilizer on the growth and chlorophyll content of the cut seedlings are positive,but the effects of transparency on that are negative.In addition,the efficiency of foliage fertilizer is obvious stronger than that of transparency.Growth indicators of new log,plant fresh weight and root fresh weight in the cutting are accelerated distinctly by application of foliage fertilizer,and so is the content of chlorophyll a,chlorophyll b and total chlorophyll.Differences between application and in application of foliage fertilizer are significant.Only in the condition of application of foliage fertilizer,the differences of the growth indicators and chlorophyll content between transparencies of 40% and 80% are significant,the differences of part indicators between transparencies 40% and 60% or 60% and 80% are significant. Without the application of foliage fertilizer,a significant difference of chlorophyll content is observed in some transparency treatments,but no significant difference is observed in the growth indicators in all transparency treatments.
