Effects of Different Delinted Ways on the Vigor and Physiological Characteristics in the Germinating Process

doi:10.7668/hbnxb.2007.S1.017

Abstract

Abstract: Compared with fuzzy seeds, the effects of different delinted ways on the cotton seed vigor and cold-resistanceof the cotton seeds were studied. the results indicated that the water-absorption rate, the relative electric conductivityof cotton seeds, the relat ive electric conductivity and the MDA content in the radicles improved significantly; Contents ofthe soluble protein and the soluble sugar, the germination percentage decreased remarkably. It was concluded that the cottonseeds delinted were harmed and the cold-resistance decreased significantly. The protective effect of mechanical delintedcotton seeds for vigour and cold-resistance was superior to delinted with sulfuric acid.

Key words: Cotton seed, Delinted ways, Vigor
