Uniconazole Nanotechnology And Its Implications For The Development Of Agents Poa Growth In Seeding Stage And Effects Of Drought

In this paper, the use of ultrasound law, 5 percent by WP Uniconazole for nano-technology processing, preparation of a certain concentration (7.5mg / L) Uniconazole of nano-formulations, after scanning electron microscopy, the treated particles Uniconazole particle size can be achieved between 50nm-300nm. Will be developed in preparation of nano Uniconazole diluted into different concentrations on Kentucky bluegrass (Poa pratensis L1) seed germination, seedling growth, root development conditions, drought resistance, such as a series of studies done. The results are as follows:With different concentrations of nano-formulations Uniconazole (0.25mg / L, 0.5mg / L, 1mg / L, 2.5mg / L) and the same concentration of agent for Kentucky bluegrass seed germination and seedling experiments, results showed that: 1mg / L ( satisfied), compared with CK, can improve the germination rate of 18.6%, 1mg / L (satisfied) with the same concentration compared to the original agent can improve the germination rate of 6.81 percent for the best concentration. 2.5mg / L (satisfied), compared with CK, to increase Kentucky bluegrass tiller number of 85.21%, 2.5mg / L (satisfied) with the same concentration of the original agent to enhance tillering 12.7%, the most obvious effect.With different concentrations of nano-Uniconazole preparations (2.5mg / L, 5mg / L, 7.5mg / L) and the same concentration of the original agents seedling experiments, results showed that: Nano Uniconazole agents can significantly increase the efficacy, the treatment group Kentucky bluegrass plants to reduce plant height, leaf width, root weight, root length, root cap than increasing. One of 7.5mg / L (satisfied) on leaf length and leaf width impact on the most obvious to deal with a long 15 days after the leaf of the control group only 43.08%, and leaf width increased by 17.62%; 5mg / L (satisfied) the impact of root The most obvious, compared with CK, root weight, root length, root cap, respectively, an increase of more than 72.1%, 82.6%, 83.15%.Different concentration of nano-Uniconazole preparations (2.5mg / L, 5mg / L, 7.5mg / L) and the same concentration of agent applied to deal with drought stress, as Kentucky bluegrass, the study shows that: the treatment group than in the control of chlorophyll, soluble sugar content were increased; description of optical capacity contracts, the accumulation of organic matter increased capacity. At the same time, the treatment group than in the control increased proline content, lipid peroxides to reduce the MDA content, electrolyte leakage rate, the above indicators are a reflection of Kentucky bluegrass increased drought. The test group of antioxidant enzymes SOD, POD, CAT activity decreased with drought stress, but downward trend in treatment group was significantly lower than the control group on preparation of nano Uniconazole Kentucky bluegrass treated to enhance drought resistance. Uniconazole preparation of nano-Kentucky bluegrass seed germination, seedling growth and drought resistance mechanism of the impact remains to be further studied.
