چکیده مقاله :
پنبه از جمله گیاهانی است که معمولا بیش از حد متعارف رشد و نمو می‌یابد از این رو نسبت به تغییرات محیطی بسیار حساس می‌باشد. این رشد رویشی نا محدود نه تنها سبب دیررسی محصول و افت کیفیت می‌گردد بلکه آفات، بیماری‌ها و هزینه تولید را افزایش داده و مشکلاتی را در امر برداشت پنبه ایجاد می‌کند. پیکس یک تنظیم کننده رشد گیاهی می‌باشد که سبب کاهش رشد رویشی پنبه می‌شود.این تنظیم کننده مانند یک آنتی ژیبرلین عمل کرده و مانع از سنتز این هورمون می‌شود. تا کنون مطالعاتی در مورد اثر پیکس بر رشد گیاه صورت گرفته است ولیکن اطلاات اندکی در مورد اثر پیکس بر فرایندهای بیوشیمیایی موجود می‌باشد. در این تحقیق اثر غلظتهای مختلف پیکس شامل 0 (شاهد)، 10، 20، 30 و 40 پی پی ام بر درصد جوانه زنی، طول ریشه چه، میزان قندهای محلول و نشاسته، فعالیت آنزیم‌های کاتالاز، پراکسیداز و پلی فنل اکسیداز در دانه‌رست گیاه پنبه مورد ارزیابی قرار گرفت. نتایج نشان داد که درصد جوانه‌زنی با افزایش غلظت پیکس ازدیاد یافت و طول ریشه چه تا غلظت20 پی پی ام روند صعودی و در مقادیر بالاتر روند نزولی را طی نمود. همچنین با افزایش غلظت پیکس میزان قندهای محلول کاهش و نشاسته افزایش یافت.فعالیت کاتالاز کاهش ولیکن بر فعالیت انزیم پلی فنل اکسیداز افزوده شد.فعالیت پراکسیداز نیز تا غلظت 20 پی‌پی‌ام روند صعودی را طی نمود.
Cotton has non limitation growth and is sensitive to environmental changes and usually grows more than natural dimension. These non limitation growths not only cause serotine of product and quaility deacresing but also increase pests, disease and harvesing expenses in cotton. Pix is one plant growth regulator that cause decrease vegetative growth in cotton.It acts as antigibberellin and inhibits synthesis this hormone. There are some researches about effect of pix on growth parameters of cotton but a little information's are about pix effects on biochemical reactions and antioxidant systems. In this research effect of different concentrations of pix includes 0 (control)10, 20, 30 and 40ppm on germination percentage, radicle length and Catalase peroxidase and polyphenol oxidase in cotton seedling was evaluated. Our results showed that percentage of germination increased with increasing pix concentration. Lenght of radicle increased until 20 ppm and decreased in concentration 30 and 40 ppm of pix. Also with increasing of pix amount of soluble sugar increasd and starch content decreased Catalase activity decreased while polyphenol oxidase activity increased. Activity peroxidase also increased until 30ppm concentration.
