چکیده

اثر تنش آبی و مصرف مقادیر مختلف زئولیت بر برخی صفات گندم با اجرای آزمایشی در سال زراعی 1390-1389 به­صورت کرت­های یک­بار خرد شده در قالب طرح پایه بلوک­‌های کامل تصادفی با سه تکرار ارزیابی گردید. تنش آبی در چهار سطح شامل آبیاری بر اساس نیاز آبی گیاه (شاهد)، آبیاری به میزان 85 درصد، آبیاری به میزان70 درصد، آبیاری به میزان 55 درصد نیاز آبی و مقادیر زئولیت در چهار سطح شامل عدم مصرف زئولیت (شاهد)، مصرف زئولیت به مقدار سه تن، شش تن و نه تن در هکتار در نظر گرفته شدند. در این بررسی، صفاتی نظیر طول پدانکل و ریشک، تعداد سنبله در مترمربع، عملکرد دانه، هدایت الکتریکی در دماهای 50 و 60 درجه سلسیوس اندازه­گیری شدند. نتایج نشان داد که اثر متقابل تیمار تنش آبی و سطوح مصرف زئولیت بر صفات تعداد سنبله در متر مربع، عملکرد دانه، هدایت الکتریکی معنی­دار بودند. مقایسه میانگین­ها نشان داد که اثرات متقابل کمترین مقدار هدایت الکتریکی ناشی از تخریب غشای سلولی توسط تیمار آب50 و 60 درجه سلسیوس با میانگین 447 و 476 میکروزیمنس بر سانتی­متر مربوط به تیمار تنش آبیاری شاهد + مصرف 9 تن در هکتار زئولیت بود. همچنین، در بین سطوح مختلف مصرف زئولیت، میانگین کاهش عملکرد دانه ناشی از تیمار عدم مصرف زئولیت، معادل 79/16 درصد نسبت به تیمار مصرف نه تن در هکتار زئولیت بود. به­طوری­که، مصرف نه تن در هکتار زئولیت با میانگین 4901 کیلوگرم در هکتار بیشترین عملکرد دانه را به خود اختصاص داشت.

چکیده [English]

Electrical conductivity of wheat cell sap and chlorophyll concentration of its leaves under drought stress and application of zeolite were evaluated in a split plot experiment, by using a RCBD with three at Arak Payam-Noor University in 2010. Treatments were four levels of water stress (I0= control irrigation, I1= irrigation at 85% of I0, I2= irrigation at 70% of I0, I3= irrigation at 55% of I0) assigned to the main plots and four levels of zeolite applications (Z0= without zeolite application, Z1= 3 t.ha-1, Z2= 6 t.ha-1, Z3= 9 t. ha-1) to the sub plots. Sub plots consisted of 4 rows of 5 m long spaced 50 cm apart and 20 plants per meter on the rows. In this study traits like peduncle length, awn length, number of spike per m-2, grain yield, electrical conductivity by using water with 50and 60oC were assessed. Results indicated that intraction effect of water stress and zeolit application on number of spike per m2, seed yield, and electrical conductivity at 50and 60oC water were significant. Mean comparisons of intraction effects showed that electrical conductivity of water with 50 and 60 oC (447 and 476 respectively) resulted in the least detrimental effect on cell membrane. Results also revealed that electrical conductivity at control irrigation (554 µs.cm-1) and application of 9 t.ha-1 of zeolit produced highest seed yield (4901 kg.ha-1) at wheat.
