Crop chemical regulation, based on roles of hormones in plant growth and development, has proved to be an effective and potential novel approach for crop cultivation. Although there are some reports in molecular mechanism of hormonal regulation applying model plant like Arabidopsis, how hormones regulated important agronomic traits of crops under field condition, such as plant height and lodging.resistance, is also poorly understood. My research group has been working on the physiological mechanisms of hormonal regulation in crop growth and development, and the development of new cultivation technical systems applying plant regulators to resolve problems in crop production. Firstly, we revealed the hormonal regulation mechanism of internodes elongation in maize stem. We proposed the.complementary effects between ethephon and diethyl aminoethyl hexanoate for the first time, invented a new formulation of plant regulator and got registration on maize. Based on compound effects among chemical regulation and other cultivation factors, including maize varieties, sowing date, plant density, fertilizer and irrigation, we developed a new comprehensive cultivation system, resulting in lodging resistance and high yield. Secondly, we presented auxin/cytokinin ratio regulated lateral root initiation and roots apical dominance in maize and cotton seedlings, which helped us to establish the chemical regulation techniques for transgenic insecticide Bt cotton, with stronger roots and robust growth in seedling stage. Thirdly, we found the effects of salinity on toxins expression and insecticidal activity, and indicated that cronatine, a new plant growth regulator, could improve the NaCl tolerance of Bt cotton. Our research findings have been published on influential agronomy journals, such as Journal of Agronomy and Crop Science, Journal of Plant Physiology, and 15 related invents patent have been authorized in China. As the leader of the project “Application and development of new crop growth regulators based on diethyl aminoethyl hexanoate”, I was awarded the second prize of National Award for Technological Invention in 2012.　In addition, I won the second prize of National Award for Science and Technology Progress in 2007 and 2013 respectively, Science and Technology Award for Chinese Youth in 2010, and some other awards for science and technology from Ministry of ducation and Ministry of Agriculture. For my outstanding scientific and technological achievements, I had been supported by Program for New Century Excellent Talents in University from 2006 to 2009. My further research plan is to study molecular regulation mechanism of maize internodes elongation, using genome-wide transcriptomics, to develop a model for lodging-resistance assessment, and provide theoretical basis for maize cultivation and plant-type breeding for lodging and drought resistance, high yield and high efficient.
