Abstract: | Most plant growth regulators available are synthesized and tend to be dangerous if used inappropriately.Emistim C AS is a natural plant growth regulator,with less side-effect.The research performed an assessment on Emistim C AS application in watermelon cultivation in a greenhouse.The results showed that 0.11% Emistim C AS increased reducing sugar by 15.49%,soluble solid by 13.7%,Vc content by 3.72%,titratable acid by 18.1%,and yield per hectare by 18.01%,so that watermelon quality and yield were both improved.Emistim C AS can be widely promoted in watermelon cultivation in future. |
