Title

Changes in Growth Indices of the Almond ‘ Shahroud 12’ Grafted on some Prunus Rootstocks under Salt Stress

Pages

  93-105

Abstract

 Almond is highly sensitive to salt stress and one way to reduce the negative effects of this type of stress is to select a tolerant rootstock/scion. Keeping these in mind, the present experiment investigates the effects of salinity stress on some morphological, physiological, and nutritional traits of almond rootstocks with the help of a factorial experiment, conducted at Horticultural Research Institute in 2017, which was based on a completely randomized design with two factors (eight levels of rootstock/scion compositions and five levels of salinity) and in three replications. Results show that by increasing salinity from zero to eight ds/m, the highest and lowest amount of reduction in root dry weight can be observed in ‘ Shahrood 12’ /Tetra (37. 8%) and GN15 (14. 5%), respectively. Also, the lowest and highest dry weight loss in the main branch can be seen in bitter almond seedling (38. 2%) and ‘ Shahrood 12’ / GN15 (47. 9%), respectively, with the highest amount of necrosis, observed in bitter almond seedling (28. 98%) and the lowest value in ‘ Shahrood 12’ /GF677 (9. 9%). Based on the experiment, the lowest and highest changes in electrolyte leakage occurred at the rootstock of GF677 (30. 74%) and GN15 (42. 93%) with the lowest and the highest changes in sodium belonging to ‘ Shahrood 12’ /GF677 (51. 2%) as well as bitter almond seedling (82%), respectively. The results also show that by increasing salinity stress, the amount of root and leaf nutrient elements ascends initially, then to drop as salinity levels are increased further. Based on the results, ‘ Shahrood 12’ /GF677 is the most tolerable combination and ‘ Shahrood12’ , Grafted on bitter almond seedling, is the most sensitive to salt stress.
