| Abstract | ||
| This study was carried out in a private nursery at Baquba City, Diyala governorate for the period from 24/2/2013 to 13/12/2014 to study the effect of humic acid spray on lemon (Citrus lemon L.) seedlings budded on sour orange (Citrus aurantium L.) and swingle citrumelo rootstocks tolerance to irrigation with saline water .One-Year old Lemon seedlings budded on two citrus rootstocks (Sour orange, and Swingle Cirumello) irrigated with three levels of saline water (0.7,3.0 , and 4.5 ds.m-1) and sprayed with two concentrations of humic acid (0, and 1%). The study results revealed that the irrigation with the highest level of saline water (4.5 ds.m-1) caused a significant decrease in mean increase of rootstock diameter ,bud length and diameter, as well as leaf area and leaves number. Whereas the application of humic acid at 1% resulted in a significant increase in these traits as compared with control treatment. Seedlings budded on swingle citrumelo have the superiority over that budded on sour orange in leaves number and leaf area. | ||
