Study on the Impact of Water Deficit on Agronomic Characters of Sunflower Based on Gray Relation Projection Model

摘要：

The paper applies gray relation projection model to analysis agronomic traits of water deficit at five different growth stages. The results showed the water deficit scheme of seeding>eight pairs true leaf stage> maturity stage>inflorescence formation stage>flowering stage, better reflecting the critical period of sunflower, so as to allocate the limited water resource rationally and effectively and make agronomic traits achieve comprehensive optimal. At the same time, the evaluation results and the actual results are better uniform through applying gray relation projection method, which show that the model is feasible during the analysis study on water deficit for agronomic traits of sunflower.
