Silicon and Nitric Oxide Applications Allow Mitigation of Water Stress in Myrobalan 29C Rootstocks (Prunus cerasifera Ehrh.)

(1) Background: Silicon (Si) and nitric oxide (NO) have been proven to protect against cellular injury caused by stress conditions, mostly salinity water in agriculture. (2) Methods: The goal was study the effect of soil applications NO, Si, their combination (Si+NO) on response Myrobalan 29C rootstocks (Prunus cerasifera Ehrh.) subjected well-watered conditions. (3) Results: results showed that decreased growth parameters (i.e., leaf area, shoot dry weight, root fresh relative diameter), physio-biochemical chlorophyll content leaves), minerals P, Ca, Fe, Zn leaves N, K, roots), compared plants. Under these all treatments mitigated detrimental effects rootstocks, being most effective Si+NO treatment. (4) Conclusions: These findings briefly highlight silicon may provide greater tolerance rootstocks.
