项目摘要

In this study, the environmental control to promote the rooting and the growth of a root and a shoot of a cutting seedling in the mass propagation was discussed. It is thought a promotion of the photosynthesis is important because the production rate of the carbohydrate of a cutting affects the rooting and the growth of a root and a shoot. Therefore, the effects of CO_2 enrichment on the rooting and the growth of cuttings were tested with the rose and chrysanthemum which were usually propagated by vegetative propagation. The effects of the number of leaflets (leaf area) of a cutting on the rooting and the growth of a root were also tested.(1) Effect of CO_2 enrichment on the root growthThe dry weights increase of a root of the rose and chrysanthemum under CO_2 enriched condition were 1.4-2.0 times greater than those under CO_2 non-enriched condition. CO_2 enrichment promoted the growth of root of a cutting.(2) Effect of CO_2 enrichment on the shoot growthCO_2 enrichment promoted also the growth of a newly shoot.(3) Effect of the number of leaflets (leaf area) on the growth of cuttingThe growth of a root was promoted with the increasing of the leaflets of a cutting, however the growth of a newly shoot was suppressed with the increasing of the leaflets of a cutting.(4) Effect of a rooting accelerator on the growth of a cuttingThe growth of a root was promoted with the rooting accelerator treatment, however the growth of a newly shoot was suppressed considerably with the rooting accelerator treatment. However the suppression of the growth of a newly shoot with the rooting accelerator treatment was decreased under CO_2 enriched condition.As the results, it is thought that CO_2 enrichment was effective environmental control method to promote the growth of a root and a newly shoot.

本研究探讨了在大量繁殖过程中促进插条苗生根和根、芽生长的环境控制。人们认为促进光合作用很重要，因为插条的碳水化合物的生产率影响生根以及根和芽的生长。因此，以通常采用无性繁殖的玫瑰和菊花为对象，测试了CO_2富集对生根和插条生长的影响。还测试了插条的小叶数(叶面积)对生根和根系生长的影响。(1)富集CO_2对根系生长的影响玫瑰和菊花在富集CO_2条件下根部干重增加量是非富集CO_2条件下的1.4~2.0倍。 CO_2富集促进了插条根的生长。(2)CO_2富集对地上部生长的影响CO_2富集还促进新芽生长。(3)小叶数(叶面积)对插条生长的影响随着插条小叶的增加,根的生长得到促进,但新芽生长则随着插条小叶的增加而受到抑制。(4) 生根促进剂对插条生长的影响生根促进剂处理促进了根的生长，但是生根促进剂处理显着抑制了新芽的生长。而在富CO_2条件下,生根促进剂处理对新梢生长的抑制作用减弱。因此,认为富CO_2是促进根和新梢生长的有效环境控制方法。
