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

چکیده [English]

Copper (Cu) is an essential micronutrient for plant growth and a potentially toxic heavy metal. Copper application can have a significant impact on Mn, K, P and other nutrients role in plants nutrition. In this study checked out the effect of applied Cu on corn (Zea mays L.) growth, concentration and uptake of Cu, Mn, K and P in 21 calcareous soils. To measure the concentration and content of the nutrient of the study, in a greenhouse experiment, corn plant (Zea mays L.) single cross 704 variety cultivated in two levels of Cu, zero (control) and 7.5 mg Cu kg-1 soil as CuSO4.5H2O. The experiment was carried out as factorial in a randomized complete blocks design with three replications. According to the results, by application of copper, significant (p
