Study on the Conductivity of Rhodamine B in Three Plants
In this work,the Rhodamine B was selected as fluorescent tracer to investigate its conductivity on soybean,maize and tobacco seedlings.The results suggested that Rhodamine B could be detected in the aboveground parts of hydroponic treated plant seedlings,therein,soybean seedlings had the highest content in part of true leaves,the leaf sheath of maize seedlings had a higher content compared with leaves,and tobacco seedlings had a higher content in the stem than leaves.There was no significant difference in fresh weight between Rhodamine B treated plants and untreated plants.And choosing tobacco seedlings as the model crop,the fluorescence intensity was dedected by in vivo ima-ging system.The results showed that the fluorescence intensity was the highest in leaves and stems with treat concentrations of 15 mg/L and 30 mg/L,respectively.
