| چکیده | ||
| استفاده از ترکیبات شیمیایی بمنظور افزایش و حفظ رشد رویشی و زایشی در محصولات باغی رواج یافته است. اسید هیومیک یکی از مواد آلی میباشد که بدلیل رهاسازی موادغذایی بعنوان محرک رشد میباشد. در این تحقیق تاثیر اسید هیومیک با غلظت 50 و 100 میلیگرم بر لیتر در دو مرحله 30 و 45 روز بعد از تمام گل، روی درختان پسته رقم اکبری بررسی شد. سپس ویژگیهایی نظیر سطح برگ، شاخص کلروفیل، طول و قطر شاخه سال جاری، درصد پوکی، خندانی، درصد میوههای بدشکل، وزن میوه، تعداد میوه در خوشه، وزن خوشه و عملکرد مورد مطالعه قرار گرفتند. نتایج نشان دادند که بیشترین میزان سطح برگ، طول و قطر شاخه مربوط به درختان پسته که با اسیدهیومیک 100 میلیگرم بر لیتر در 30 روز بعد از مرحله تمام گل، مشاهده گردیده است. کمترین درصد پوکی در میوههای تیمار شده با اسید هیومیک 50 میلیگرم بر لیتر مشاهده شده است. بطوریکه بیشترین وزن خوشه و تعداد میوه در خوشه در درختان تیمار شده با اسیدهیومیک 100 میلیگرم بر لیتر دیده شده است. افزایش میزان عملکرد و وزن میوه در هر دو زمان تیماردهی، با زیاد شدن غلطت اسید هیومیک تا 100 میلی گرم در لیتر مشاهده شده است. درصد میوه بدشکل در میوههای شاهد در هر دو مرحله از محلولپاشی، نسبت به میوههای تیمار شده با اسیدهیومیک افزایش یافته است. | ||

| چکیده [English] | ||
| The use of chemical compounds to increase and maintain vegetative and reproductive growth in horticultural products has become common. Humic acid is an organic substance that stimulates growth due to the release of nutrients. In this study, the effect of humic acid with concentrations of 50 and 100 mg/L in two stages 30 and 45 days after flowering, were sprayed on pistachio trees of Akbari cultivar. Then, characteristics such as leaf area, chlorophyll index, branch length and diameter of the current year, percentage of hollow, split rate, percentage of deformed fruits, fruit weight, cluster weight and number of fruits per cluster, and yield were studied. The results showed that the highest leaf area, length and branch diameter were related to pistachio trees with 100 mg /L humic acid in 30 days after full flowering stage. The lowest percentage of hollow was observed in fruits treated with humic acid 50 mg /L. The highest cluster weight and number of fruits per cluster was observed in trees treated with humic acid 100 mg /L. The highest cluster weight and number of fruits per cluster was observed in trees treated with humic acid 100 mg /L. Increased yield and fruit weight in both treatments were observed with increasing humic acid concentration up to 100 mg/L. The percentage of deformed fruits in control fruits increased in both stages of foliar application compared to fruits treated with humic acid. | ||
