اثر محتوای فسفر برگ و بنه بر خصوصیات رشدی بنه های دختری زعفران

Abstract

To investigate the role of various nutritional elements, especially phosphorus, on the quantitative and qualitative production of saffron and the relationship between the phosphorus element of corm and leaf with the size of doughter corms, an experiment was carried out in 2019 in a farm in Neishabor city as a randomized complete block design with three replications. The amount of leaf phosphorus was taken from the plots 10 days after foliar spraying, and the amount of leaf phosphorus was measured at the end of the growth period in June. Sigma Plot software was used to check the correlation between the phosphorus content of the corm and the number of small and large corms and the average corm weight. The results showed that the phosphorus content of the corm had a negative linear correlation with the number of small corms (less than 8 grams). However, the relationship between the number of large corms (more than 8 grams) and the phosphorus content of corms showed a high correlation and the relationship was a quadratic equation. As the amount of leaf phosphorus increases, the number of small corms decreases, and the number and average weight of daughter corms increases. A direct negative linear relationship was observed between leaf phosphorus content and the number of small corms. As the amount of leaf phosphorus increases, the number of small corms decreases, and the number and average weight of daughter corms increases. A direct negative linear relationship was observed between leaf phosphorus content and the number of small corms. On the other hand, there was a high correlation between leaf phosphorus and the number of large corms. It is suggested that farmers should take necessary measures to provide adequate phosphorus in the soil to produce large corms
