超声波用于处理林木种子获得良好效果,国内资料已有报道,如用频率25千赫兹处理马尾松、檫树种子20分钟,发芽率比对照组分别提高25％和19％。我们选用马尾松种子作材料,经超声波处理,分别作了种子发芽试验与幼根测置;种子呼吸强度与吸水力的测定;种子吸水量与干物质消耗量的测定;幼根组织切片初步观察,并进行了初步的分析研究,现简介如下:
Ultrasonic treatment of tree seeds to obtain good results, domestic data have been reported, such as frequency of 25 kHz treatment of Pinus massoniana and Salvia seeds for 20 minutes, the germination rate increased 25% and 19%, respectively, compared with the control group. We choose the seeds of Masson pine as the material, after ultrasonic treatment, respectively, made the seed germination test and rooting measurement; Determination of seed respiration intensity and water absorption; Determination of seed water absorption and dry matter consumption; Preliminary observation of root tissue sections , And carried out a preliminary analysis of the study, are as follows:
