摘要

摘要: 以8个汴梁西瓜品种（京引21、花皮88、圳板、郭牟、金玫黑、金小兰、日本瓜和蜜玫绿）为实验材料，采用样本率的显著性检验、t检验及单因素方差分析方法，研究了26～28 MPa的高氮气压及50～150 MPa的高静水压处理种子对西瓜出苗率、叶绿素含量、过氧化物酶活性、单瓜重、含糖量等生长特性的影响。结果表明：高压处理会显著（P0.05）或极显著（P0.01）地降低西瓜的出苗率和幼苗期叶片的类胡萝卜素含量，提高幼苗期叶片的叶绿素a含量和过氧化物酶的活性。高压处理种子对于含糖量和单瓜重这两个农艺性状的影响，品种间存在较大差异。其中，在50～150 MPa高压下处理种子20 min主要影响日本瓜（P0.001）和金小兰（P0.092）的单瓜重以及郭牟的含糖量（P0.064）。

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.
