Abstract: The 6-benzyladenine (6-BA) solution alone or in combination with surfactant "Yue Fu No. 2" (YF-2) were applied to rice seedlings. YF-2 significantly decreased the surface tension and contact angle, and increased the wetting power of 6-BA solution, hence YF-2 enhanced the absorption and the uptake of 3H-6-BA in rice seedling leaves. 6-BA+YF-2 treatment effectively retarded the degradation of chlorophyll in the dark, maintained a higher photosynthetic rate during senescence. Moreover, YF-2 had a function of rain-fastness, reducing the amount of 6-BA to washed away by rain. The optimal concentration of YF-2 is 200 mg /L, which could decrease the amount of 6-BA needed by slightly more than one third and reduce the production cost also.
