| Abstract: |
| In this work, the morphological indexes and photosynthetic characteristics of mung bean plant were studied using variety “Lufeng 2” that the seeds coated by a mung bean\|specific seed coating agent developed by our laboratory. Regular and microbiological soybean seed coating agents were used as positive controls, and uncoated seed was used as negative control. The results showed that the mung bean\|specific seed coating agent with suitable concentrations (100% （Z3） and 125% （Z4） active ingredients) can effectively enhance the photosynthetic performance through increasing the chlorophyll content and net photosynthetic rate (both are significantly higher than various controls, such as CK0, CK1 and CKW) as well as stomatal conductance (Z3 was extremely significantly higher than the various controls at least by 46.97%~84.82%). Compared with the advantage control (regular soybean seed coating agent), it also decreased the plant height more than 0.20~1.63 cm, increased the stem diameter, root length, and number of lateral roots at least by 2.07%~6.74%, 14.85%~20.30%, and 11.81%~27.57%, respectively. Thereby, regulating the above\|ground and below\|ground dry mass accumulation and the plant morphology of mung bean seedlings, and ensuring the healthy growth of the mung bean seedling. |
