Abstract:
Taking main aerial sowing forages Canagana microphylla,C.intermedia and C.korshinskii as test materials,the effect of three different rhizogenic agent NK-Ⅱ-298,NK-Ⅱ-888 and NK-Ⅱ-16 on seeding growth and eco-physiology characteristics of them were studied.The results showed that utilization of rhizogenic agents affected plant height and biomass of plants and difference was found between species,however,their final growth performance was not affected.All three rhizogenic agents increased the net photosynthetic efficiency of C.microphylla significantly,only NK-Ⅱ-16 increased the net photosynthetic efficiency of C.intermedia,and NK-Ⅱ-888 and NK-Ⅱ-16 increased the net photosynthetic efficiency of C.korshinskii.For chlorophyll contents,only chlorophyll b of C.korshinskii was increased by three rhizogenic agents.Response to rhizogenic agents varied for different Canagana species.
