摘要
用浓度 5 0 0 mg/L 的人体医用激素和几种植物生长调节剂对 6龄杜仲树皮增厚作用进行比较表明 ,经过一个年生长周期 ,医用激素使杜仲皮厚度从 1.2 mm增加到 3.5mm,是对照部位皮厚度的 2 .2倍 ,比 ABT1#多增厚 2 0 %,比 NAA多增厚 37%。在树皮增厚的同时 。
The thickening effects of medical hormone and plant grouth regulators on the bark of 6 year Eucommia ulmoides trees were compared.The results showed that medical hormone made the bark thickness increased to 3.5 mm in one year growth period, 2.2 times as thick as the contrast position. The increase by medical hormone was 20% more than ABT1 #,37% more than NAA. Xylem of trunk thickened obviously at the same time while the bark was thickened.
