In grafted apple combinations, rootstocks can increase the stress tolerance of plants, influence scion growth, and harbor a rich microbial community. However, whether scions modify plant rootstock phenotypes rhizosphere bacterial communities has not been clearly investigated. Here, 14 different combinations two cultivars on 7 genotypes were used as research materials, we analyzed traits, commun...

Supplemental irrigation under prolonged drought conditions has a key role in providing water for transpiration of rain-fed fig trees. The effect of different times and amounts of supplemental irrigation at different distances from the tree trunk on quantity and quality of Estahban rain-fed fig production was evaluated during two years. A randomized complete block design with four replications o...

This research was conducted to measure quantitative and qualitative characteristics of trees and to determine amount of annual increment for poplar and plane, specially their volume and wood production beside Zayanderud dam. Two plantation areas with 3×3 meters spacing were selected for sampling after field survey. A 30-years-old poplar and a 30-years-old plane stand. In each stand, five tree l...
