Research on Softwood Cutting Propagation Technology for Actinidia arguta
摘要
Abstract
In order to study the influencing factors of Actinidia arguta softwood cutting,annual branches of A.arguta were used as experimental materials to study the effects of growth regulator(IBA)concentration and cutting substrate on the rooting rate,root width,root length,and new shoot length of softwood cuttings.The membership function method was used to obtain the optimal reproductive conditions for softwood cuttings of A.arguta.The results showed that the concentration of IBA had a significant effect on rooting rate and new shoot length of female plants cuttings,while it had a significant effect on root width and root length of male plants cuttings.At the same IBA concentration,there were significant differences in some rooting indicators between female and male plants.The cutting substrate had a significant effect on the rooting rate,root width,root length,and new shoot length of A.arguta.The scoring results of the membership function indicated that the highest score for female cuttings was 0.706 at IBA 6000 mg/L,while the highest score for male cuttings was 0.780 at IBA 2500 mg/L.The order of cutting substrates scores was coconut coir:perlite=1:2(volume ratio)(0.997)>peat:perlite=1:2(volume ratio)(0.933)>coconut coir(0.911)>peat(0.872)>cooked rice husk:perlite=1:2(volume ratio)(0.635)>cooked rice husk(0.027).In summary,the optimal concentration of IBA for softwood cuttings of A.arguta female plants is 6000 mg/L,and for male plants it is 2500 mg/L.The best cutting substrate for softwood cuttings of A.arguta is coconut coir:perlite=1:2(volume ratio)and peat:perlite=1:2(volume ratio).关键词
