Application of stereo-device for cuttage and plant growth regulators on cutting propagation of Ginkgo biloba

Abstract: The half-matured cuttings of Ginkgo biloba were treated by four methods :T1 dipping the cutting base in 100 mgL-1 solution of ABT-1 rooting powder for 1 hour , and then inserting them into a stereo-device for rooting ;T2 dipping the cutting base in water for 1 hour and then inserting them into a stereo-device for rooting ;T3 after the similar ABT-1 treatment inserting the cuttings into a rooting bed ;T4 after the similar water treatment inserting the cuttings into a rooting bed .The rooting medium was composed of vermiculite and perlite in a 1∶1 ratio .A complete randomized block design was used for experiment .The results showed that the T1 treatment was the best one among others , with 73.00 % of the first year 's survival , 56.00 %of the first year 's stocking , and 89.00 % of the second year 's transplant survival which equals 17 , 29 and 2 times , respectively , that of T4 treatment .The plant density in T1 was 10 times that in T4 .In the second year the growth and biomass of roots , stems and leaves in T1 treatment were significantly larger than those in T4 .The estimates of physiological and biochemical features similarly indicated higher chlorophyll content , endogenous IAA , GA 1/ 3 and iPA contents in T1 than others , but lower ABA content in the former than the latters .It was concluded that ABT treatment plus stereodevice for rooting could greatly promote the effectiveness of ginkgo cutting propagation by regulating the physiological and biochemical mechanisms inside of plants and cultivate much more superior stocks .
