Product description:The endogenous ga3 synthesis inhibitors. Also can increase the activity of indole acetic acid oxidase rice, the levels of endogenous IAA reduce rice seedlings. Apparently less rice Seedling growth advantage at the top, promote lateral bud (the tiller) breeding. Stocky seedling appearance performance more tillers, thick green leaf color. The root system developed. Anatomy study, multi-effect azole can make rice seedlings roots, leaf sheath and leaves the cell size, each organ cells layer increased. Tracer analysis showed that the rice seeds, leaves, the roots can absorb multi-effect azole. Leaf absorbs most of the changes of the stranded in absorption section, rarely outward transportation. Leaves low density increased in rice seedlings of photosynthetic efficiency; High concentration of inhibition of photosynthesis efficiency. Improve root respiration intensity; Lower part on respiration intensity, improve leaf stomatal resistance, reduce foliar transpiration.
