پیشرفت های اخیر در تغذیه عناصر ریزمغذی در زعفران

Abstract

The role of plant nutrition with macro and micro elements is not hidden from anyone. Although the consumption of microelements in plants is low, this does not mean that they are less important in the process of plant growth and development. In saffron, little research has been done regarding the effects and amount of these elements, so it is necessary to conduct research in this field. Considering that there are very few studies especially about manganese and copper elements, therefore, in this article, an attempt has been made to evaluate the importance and the few results of research in this field on saffron. Based on this, during the last few years, a series of studies have been designed and carried out in University of Torbat Heydarieh and Saffron Institute on the effects of micro elements on quantitative and qualitative performance in the form of student theses and research projects. According to the results, the role of manganese element in improving the quality of saffron and the role of copper element in improving the quantity of stigma has been determined.
