Effects of Super Absorbent Polymers and Gibberellin on Germination and Growth of alfalfa

Abstract

For proven effects of eco-friendly super absorbent polymer and gibberellin on germination and growth of alfalfa, taking the germination and growth test in the artificial climate box by adding the different amount of super absorbent polymer and gibberellin. Observed the germination potential, germination rate, shoot length, root length, fresh weight and dry weight, under the different experiment conditions. The test showed that the super absorbent polymer had a promoting effect on alfalfa. The property of slowly release water, water supply on super absorbent polymer could keep plants prolonging the survival rate in the case of insufficient water supply. It could improve the germination rate of the seed of alfalfa. Adding super absorbent polymer and gibberellin not only improved the survival rate, but also promoted the growth of root and shoot on alfalfa.
