Study on the cutting propagation and growth variation of different Tamarix chinensis Lour.provenances and clones
Study on the cuttings and growth performance of 33 Tamarix chinensis Lour.clones from 4 provenances (YC,HK,KL,LJ) showed:there were significant variation in survival rate,growth of cutting seedlings among provenances and clones,while variation among clones was more evident than that among provenances.At 3a,LJ provenance demonstrated poor growth performance.There was no obvious difference on diameter at ground (DG),seedlings height (H) and the diameter of the largest branch (DB) among YC,HK and KL provenances.But YC provenance could produce more branches of ＞ lcm diameter (＞ 1 cm Br).Principal component analysis was used to evaluate these clones.Eventually clone YC-2,YC-1 as well as KL-2 were selected for their growth stability,growth speed and favorable branches.Besides,these given clones were clustered into 4 classes,and the class 1,2 and 3 can be selectively utilized according to cultivating targets.
