Evaluation of five rootstocks on the growth, gas exchanges and chlorophyll fluorescence of Juglans regia L. cv. 'Xiangling'

“…Growth. Growth is one of the most fundamental processes of plants, growth performance indexes such as PH, BD, TLA, and TDB are always been used as effective and important indicators of plant vitality (Liu et al 2012(Liu et al , 2020Shabbir et al 2021;Thapa et al 2021;Mostakhdemi et al 2022). Germplasm resources of different genotypes (species or variety) always exhibit different degrees of phenotypic variation under the same condition (Norouzi et al 2017;Khadivi et al 2018;Zarei et al 2019;Hashemi, Khadivi 2020;Arab et al 2022).…”

“…Rootstock has an important effect on the scion vegetative growth by influencing the absorption/ synthesis and transportation of water, nutrients and hormones (Nawaz et al 2016;Warschefsky et al 2016;Gaion, Carvalho 2017;Rasool et al 2020;Thapa et al 2021;Vahdati et al 2021;Mostakhdemi et al 2022). In addition, rootstocks with high stress tolerance are widely used to improve resistance of the engrafted plants to biotic and abiotic stresses, that was mainly attribute to the well-developed root system, the enhanced availability of water and nutrients, the production of phytohormones, the activated antioxidative defense system, and the up-regulated expression of genes related to stress tolerance (Schwarz et al 2010;Gaion, Carvalho 2017;Kumar et al 2017;Rouphael et al 2018;Gaut et al 2019;Vahdati et al 2021;Sadeghi-Majd et al 2022).…”
