دراسة تأثير أكسيد الزنك النانوي في مؤشرات إنبات كورمات نبات الزعفران المزروع

Abstract

This research investigated the effect of nano-zinc oxide and regular zinc oxide at three concentrations (20, 40, and 60 mg/L) on the growth indicators of cultivated saffron corms. Corms were treated at the specified concentrations for 90 minutes, then transferred to Petri dishes, along with an untreated control corm. After germination, growth indicators were measured, including the number of shoots and roots, and the length and fresh weight of both the shoot and root systems. The results showed significant differences between nano-zinc oxide and regular zinc oxide in terms of the number and length of shoots, root length, and fresh weight. Furthermore, corms treated with nano-zinc oxide significantly outperformed the control by exhibiting the highest germination indicators. This study suggests the importance of using nano-zinc oxide to improve crop productivity and growth.
