چکیده مقاله :
به منظور بررسی تاثیر غلظت و تعداد دفعات محلول پاشی سالیسیلیک اسید بر عملکرد و اجزای عملکرد ذرت در شمال خوزستان، آزمایشی در سال زراعی 94-1393، به صورت فاکتوریل در قالب طرح بلوک های کامل تصادفی با 3 تکـرار اجـرا شــد. تیمار غلظت سالیسیلیک اسید در پنج سطح شامل صفر (شاهد)، 0.25، 0.5، 0.75 و 1 میلی مولار و تیمار تعـداد دفعـات محـلول پاشی در سه سطح شـامل محلول پاشی در مرحله 8-6 برگی، دو بار محلول پاشی در مرحله 8-6 برگی و ده روز بعد از آن و سه بار محلول پاشی در مرحله 8-6 برگی و ده و بیست روز بعد از آن در نظرگرفته شدند. نتایج حاصل از آزمایش نشان داد که شاخص سطح برگ، عملکرد و اجزای عملکرد شامل وزن هزار دانه، تعداد ردیف دانه در بلال، تعداد دانه در ردیف تحت تاثیر مقادیر مختلف غلظت و تعداد دفعات محلول پاشی سالیسیلیک اسید قرار گرفتند اما برهم کنش آنها اختلاف معنی داری نداشت. عملکرد بیولوژیک تحت تاثیر مقادیر مختلف غلظت سالیسیلیک اسید قرار گرفت به طوری که، بیشترین مقدار عملکرد بیولوژیک مربوط به تیمار غلظت 0.75 میلی مولار با 18150 کیلوگرم در هکتار و کمترین آن مربوط به شاهد (بدون محلول پاشی) با 15410 کیلوگرم در هکتار بودند اما تعـداد دفعـات محلول پاشی و برهم کنش آنها اختلاف معنی داری نداشت. محلول پاشی سالیسیلیک اسید در مقادیر مختلف، عملکرد دانه را افزایش داد به طوری که بیشترین مقدار عملکرد دانه مربوط به تیمار غلظت 1 میلی مولار با 8998 کیلوگرم در هکتار و کمترین آن مربوط به شاهد (بدون محلول پاشی) با 6897 کیلوگرم در هکتار برآورد شدند و در تیمار تعداد دفعات محلول پاشی بیشترین مقدار عملکرد دانه با 8592 کیلوگرم در هکتار با دو بار محلول پاشی در مرحله 8-6 برگی و ده روز بعد از آن به دست آمد. نتیجه گرفته شد که مصرف سالیسیلیک اسید می تواند در افزایش عملکرد و رشد ذرت مؤثر باشد.
To study the effect of salicylic acid concentrations and foliar application times on yield and yield components of maize in the northern Khuzestan, a field experiment in 2014-2015, as factorial in the form of randomized complete block design with three replications was conducted. Experimental factors were salicylic acid concentration in five levels, 0, 0.25, 0.5, 0.75 1 Mm and foliar application times with three levels: once at 6-8 leaf stage, twice at 6-8 leaf stage and ten days after that, thrice at 6-8 leaf stage and twenty days after that. Results showed that the leaf area index, grain yield and yield components, like grain thousand weight, number of kernel rows per ear and number of kernels per row, were affected significantly by different salicylic acid concentrations and foliar application times, but the effect of salicylic acid concentration ×foliar application time interactions were not significant. Biologic yield was affected by different concentration of salicylic acid. The highest biologic yield of 18150 kg/ha related to 0.75 Mm salicylic acid concentration and lowest to control (no foliar application) with 15140 kg.ha-1, but the effect of foliar application times and their interactions were not significant. Foliar application of salicylic acid increased grain yield. The highest grain yield of 8998 kg.ha-1 related to 1 Mm concentration treatment and lowest (6897 kg.ha-1) to control (no foliar application). Highest grain yield (8592 kg.ha-1) belonged to two time foliar applications, at 6-8 leaf stage and ten days after that. The conclusion is that the application of salicylic acid could be beneficial in increasing grain yield of maize.
