چکیده
|
in recent years, global warming and unusually warm winters have caused many problems for pistachio production in iran. the effects of the dormex® application were studied in a randomized complete block design with three treatments and three replications on the akbari commercial pistachio cultivar in kerman province. treatments included dormex® 4%, volk oil 4%, and control, all applied in mid-february. flowering time, gum secretion, current branch length, and qualitative and quantitative yield characteristics were measured. results showed that volk oil and dormex® spring treatments caused early flowering in the akbari cultivar. the dormex® 4% treatment significantly prolonged flowering time (8 days earlier than volk oil 4%, and 12 days earlier than the control). based on the results, volk oil treatment increased gum secretion from buds and perennial shoots compared to the dormex® treatment and control. the results of yield indices showed that the weight of clusters in the dormex® 4% treatment was 2.3 times higher than the control and about 21% more than the volk oil 4% treatment, showing a significant difference with the control. dormex® and volk oil treatments increased split nut percentage by 66 % and 88%, respectively, but there was no significant difference between them. based on the results, the blank nut percentage in the dormex® 4% treatment significantly increased compared to the control and volk oil treatment by 33% and 41%, respectively. the length of current season growth in the dormex® 4% treatment significantly increased by 68% compared to the control. the volk oil 4% treatment had no significant effect on the length of current season growth compared to the control.
