چکیده | ||
مس (Cu) یک عنصر ضروری کممصرف برای تغذیه گیاهان است که به طور بالقوه سمی نیز میباشد. مصرف مس میتواند تأثیر بهسزایی بر ایفای نقش منگنز (Mn)، پتاسیم (K)، فسفر (P) و سایر عناصر در تغذیه گیاهان داشته باشد. در این پژوهش ﺗﺎﺛﻴﺮ مصرف مس ﺑﺮ ﻏﻠﻈﺖ ﻭ ﺟﺬﺏ ﻣﺲ، منگنز، پتاسیم و فسفر توسط گیاه ذرت (Zea mays L.) در 21 نمونه خاک آهکی بررسی شد. جهت اندازهگیری غلظت و میزان جذب عناصر مورد مطالعه، طی آزمایش گلخانهای گیاه ذرت علوفه ای رقم سینگل کراس 704 در دو سطح صفر و 5/7 میلیگرم مس در کیلوگرم خاک از منبع سولفات مس (CuSO4.5H2O) در سه تکرار به صورت آزمایش فاکتوریل و در قالب طرح بلوک های کامل تصادفی کشت شد. بر طبق نتایج حاصله، با مصرف مس وزن خشک شاخسار، غلظت و جذب مس شاخسار و غلظت مس ریشه افزایش معنیدار یافت (p | ||
