Abstract:
The rooting experiment of softwood cuttings of 81 clones was conducted on Catalpa,including Catalpa duclouxii, C.speciosa,C.fargesii,C.bungei and C.ovata,the influnce of different species and different provenance on rooting were studied.The results showed that rooting rate,rooting number of single cutting and length of the longest root significantlydifferentiated within the species,in which the range of cutting rooting rate was 10.06%~95.80%,the range of rooting number was 1.00~16.40,the range of the longest rooting length was 1.50~16.80 cm.Rooting capability of these clones could be divided into four categories as bad,medium,good and the easiest by cluster analysis.Based on different provenance,rooting ability of 63 clones showed significant difference among rooting rate,rooting number and length of the longest root(P<0.01).
