| Abstract: | The softwood cuttings of Larix olgensis from the nursery and the cuttings-bed were used as materials.The endogenous hormone changes of cutting woods trees in different growing stages and those of softwoodcuttings during cutting period were studied by the means of ELISA. There were significant variations in theendogenous hormones of cutting woods trees and cuttings. After softwood cuttings the content of GA4increased significantly. and the content of IPA was also higher than that of the contrast. While the contentof ABA was in the contrary situation, it decreased. GA4 and IPA could prornote callus growing andadventitious roots emerging. The endogenous hormone changes of cutting woods trees and those ofsoftwood cuttings were contrarieties. According to the endogenous hormone changes of cutting trees indifferent growing Period and other situations, the best time of cuttage is in early July. |
