    Abstract
  • By using the statistical significance test of sample rate, t-test and one-way analysis of variance (ANOVA), the effects of high pressure treated seeds on the emergence rate, chlorophyll content, peroxide enzyme activity, morphology and structure of cotyledon, average weight per watermelon and sugar content were studied in detail. In experiments, different varieties of seeds, such as Jingyin21, Huapi88, Zhenban, Guomou, Jinmeihei, Jinxiaolan, Mimeilv and Ribengua, were pretreated with high nitrogen gas pressure of 26~28 MPa or high hydrostatic pressure of 50~150 MPa at room temperature. Then the growth characteristics and main nutrition components were observed, measured and recorded. Compared with untreated controls, the experimental results showed that the germination rate and the content of chlorophyll c were significantly (P0.05) or extremely significantly (P0.01) reduced, and the chlorophyll a content and the peroxidase activity were significantly (P0.05) augmented. Additionally, the effects of the high pressure on average weight per watermelon and sugar content were obviously different in different cultivars. For Ribengua (P0.001) and Jinxiaolan (P0.092), the average weight per watermelon were strongly influenced when the seeds were treated under high hydrastatic pressure; for Guomou (P0.064), the influence noted on the sugar content was obvious.
