Prepare Nano-biological Material Of Triacontanol (TA) And Impact On The Wheat Or Mung Bean Seeding Growth

Triacontanol plants as a new regulator, is currently in our country have a wide range of applications and research. Summary of the papers in Triacontanol (TA) and application of research based on the means of dealing with the use of nano-technology, nano-prepared Triacontanol agents, through comparison, the preliminary study of the preparation of the wheat, the growth of mung bean seedlings impact. The main findings are as follows:1, By ultrasonic oscillation method to deal with the preparation of nano-Triacontanol agents, after scanning electron microscopy and transmission electron microscopy detection and calculation of the distribution of particle size analysis software the particle size Triacontanol up to 50-200nm; will Triacontanol the original agents Triacontanol preparation of nano-agents at different concentrations (0-2mg / L range:0.5mg/L,1.0mg/L,1.5mg/L,2.0mg/L) to cultivate wheat and mung bean seeds and seedlings to study the different concentrations of nano-agents and general agents of wheat and mung bean seedling growth and development.2, Different concentrations of TA can be improved germination rate and germination potential after soaking the seed, and preparations to deal with nano-TA on seed germination after the more obvious role. In, 0.5mg / L nano-agent deal with the TA after seed germination rate than the control group increased 1.2% and 3.2%..3, TA Nano-agents to deal with the strong effect of seedling growth and promote more obvious in the increase in seedling height, root length, root number and increased leaf fresh weight, dry weight. Morphological indicators of the overall performance of the most obvious is that when the concentration of 0.5mg / L TA treated nano-formulations, compared with the control group increased by 6.5% and 8.6% in seedling height, root length increased by 7.2% and 9.5%, fresh weight increase of20.5% and 21.3%, dry weight an increase of 23.1% and 26.5%.4, TA Nano-agents to deal with the physical growth of the seedlings have a certain influence, reflected in the chlorophyll content to increase and improve MDA content, increased the enzyme activity. Physiological indicators of the performance of the most obvious is that when the concentration of 0.5mg / L TA treated nano-formulations, compared with the control group, chlorophyll content increased by 26.1% and 31.2%, MDA content increased by 11.2% and 13.5%, CAT concentration increased by 20.5% and 22.7%, POD was increased of 21.3% and 26.3%.Through the ultrasonic oscillation, ball milling and other methods of preparation of nano-formulations, after exploration, the selection method using ultrasonic vibration, the Triacontanol prepared phase pure nano-agents without the existence of impurities, and particle size distribution.On to explore a wide range of preparation methods of nano-biological agents and their mechanism of action, pending further study.
