Study on Promoting Roots and Anti-aging Effect of Sprouting Roots at Jointing Stage in Wheat Huang Jubo, Yang Hongbin, Yan Wanglu, Xu Chengzhong (Precipitation Department of Jining Agro-Technology Promotion Station, 272137) The premature leaf senescence, rapid decline of grain filling intensity and the reduction of 1000-grain weight are common phenomena in high yielding fields. According to the study, the main leaf senescence is accelerated protein decomposition in leaves, chlorophyll decomposition with the decomposition of the protein, resulting in yellow leaves [1]. root...
