Comparative Study on Rooting Effect by Clonal Cuttings of Crateva unilocularis
摘要
Abstract
One year old cuttings of 11 Crateva unilocularis clones were applied to the cuttage experiment. The results showed that the tested clones expressed both cortex rooting and callus rooting ability, although the former was the major rooting type and the latter type occasionally occurred together with the former rooting type. The experiment showed that the rooting efficiency index (REI) of the 11 C. Unilocularis clones was positively correlated with the rooting rate. There was significant difference in the rooting rate among the 11 clones, the rooting rate of the clone SP10 was the highest, followed by clone SP7, while the clone SP6 had the lowest rooting rate. The average rooting number was significantly different among the clones, but there were no significant differences in the average root length, nor in the leaf number on the shoots. Both the average root length and the leaf number were significantly and positively correlated to the rooting number. Clone SP10 was screened out as a superior individual.关键词
