摘要

近年来,物理方法的生物刺激作用已经在主要农作物植物中得到了观察,氦氖激光是促进种子萌发和植物生长发育的最重要的生物物理方法之一。哈萨克斯坦小麦品种种子(品种;aksay, kazakhstanskaya-10和eretrosperum -350)和埃及(栽培品种;sakha-168)暴露于5mw的He-Ne激光照射下。Mm−2功率强度,曝光时间为1 ~ 1800秒。记录和计算各种萌发和生长参数及指标。监测超氧化物歧化酶活性、脂质过氧化水平和过氧化氢积累速率的变化。小麦种子预处理显著提高了种子发芽率、发芽率(seed.h−1)、相对发芽率系数(Wk)等各项发芽参数,并增强了各种生长参数。不同剂量的He-Ne激光可使种子萌发率提高,最高可达100粒。此外,不同剂量的He-Ne激光预处理对种子过氧化氢水平、脂质过氧化水平和Cu-Zn超氧化物歧化酶活性均有显著影响。与对照组相比,随着氦氖激光剂量的增加,过氧化氢积累和脂质过氧化水平显著增加。但与对照相比,氦氖激光预处理后铜锌超氧化物歧化酶活性下降。

Can He-Ne Laser Induce Changes in Oxidative Stress and Antioxidant Activities of Wheat Cultivars from Kazakhstan and Egypt?
Recently the biostimulatory role of physical methods have been observed in major agricultural crop plants, He-Ne laser is one of the most significant biophysical method for enhancing not only seed germination but also plant growth and development. Seeds of wheat cultivars from Kazakhstan (cultivars; aksay, kazakhstanskaya-10 and eretrospermum-350) and from Egypt (cultivar; sakha-168) were exposed to He-Ne laser irradiations with 5 mW. mm −2 power intensity for 1 to 1800 seconds exposition time. Various germination and growth parameters and indices were recorded and calculated. Changes on the rate of superoxide dismutase activity, lipid peroxidation level and hydrogen peroxide accumulation were monitored. Wheat seed pre-treatment caused significant increase in various germination parameters including germination percentage, germination rate (seed.h −1 ), relative germination rate coefficient ( Wk) and enhancing various growth parameters. Several doses of He-Ne laser promoted the germination to a maximum of 100 germination, increasing also the germination rate. Moreover, seed pretreatment with different doses of He-Ne laser caused significant changes in levels of hydrogen peroxide, lipid peroxidation an d Cu-Zn superoxide dismutase activity. Hydrogen peroxide accumulation and lipid peroxidation levels increased dramatically with the incre asing doses of helium neon laser compared to control. However Cu-Zn superoxide dismutase activities dropped following seed pretreatment with He-Ne laser compared to control.
