| Abstract/Contents: | "Research was conducted to obtain the optimum treatment of sodium hypochlorite (NaOCl) at various temperatures in the seed scarification for stimulating germination of zoysiagrass (Zoysia japonica Steud.) seed. Morphological changes of seed coat were also examined by scanning electron microscopy (SEM). 1. Differences in temperature of scarifications with 2-4% NaOCl showed little influence on promoting germination of seeds but seeds treated with 1% solution at 15°C germinated less than that of higher temperatures. The promotion effect of 4% solution on germination was diminished when seeds were treated for 8 hours of [or] more. The most favorable seed scarification unaffected by temperature for enhancing germination was 4-6hours treatment at 4% solution in fresh seeds. 2. GA3 , treatment did not enhance germination of water-pretreated control seeds but germination of seeds pretreated with NaOCl was increased additional 10% or more by GA3, water-pretreated control seeds treated with 50mM hydrogen peroxide (H2O2) germinated about 44%. In NaOCl treated seeds, H2O2 treatment increased germination additional 10% or more. 3. NaOCl and KOH treatment softened the seed coat and formed the pores by removing the scab-like thikenings [thickenings] attached to the seed surface. These results suggest that the modes of action of NaOCl in the promotion of seed germination reside in a[n] increase of the permeability of the seed coat, and in the provision of additional oxygen to the seed." |
