Proper priming techniques are among the most important methods for increasing seed germination and seedling growth. Three experiments were conducted to investigate the effects of plant hormone (500 and 1000 mg/L gibberellic acid (GA)), magnetic field (3, 15, 30 mili Tesla (mT)) and laser irradiation at 650 nm (200 mW) on the germination and the growth of Salvia officinalis. We examined the plumule and radical length, plumule and radical fresh weight, plumule and radical dry weight, germination percentage, germination rate and seed vigor. The two concentrations of GA significantly increased seed germination and seedling growth. The magnetic field at 15 mT significantly increased radical length. The effect of laser irradiation was also significant on plumule length, and fresh and dry weight, radicle fresh weight, germination percentage and rate and seed vigor. Such results may be of practical use in the field, especially in arid and semiarid areas, but more research must determine the response of medicinal sage, treated with the priming techniques tested in our experiments, under stress conditions.
适当的引发技术是提高种子发芽率和幼苗生长的最重要方法之一。进行了三项实验,以研究植物激素(500和1000毫克/升赤霉素(GA))、磁场(3、15、30毫特斯拉(mT))和650纳米(200毫瓦)激光照射对鼠尾草发芽和生长的影响。我们检测了胚芽和胚根长度、胚芽和胚根鲜重、胚芽和胚根干重、发芽率、发芽速率和种子活力。两种浓度的GA均显著提高了种子发芽率和幼苗生长。15 mT的磁场显著增加了胚根长度。激光照射对胚芽长度、鲜重和干重、胚根鲜重、发芽率和速率以及种子活力也有显著影响。这些结果在田间可能具有实际用途,特别是在干旱和半干旱地区,但更多的研究必须确定在我们实验中测试的引发技术处理下的药用鼠尾草在胁迫条件下的反应。
