“…Decrease in RWC in plants under drought stress may depend on plant vigor reduction and have been observed in many plants (Liu et al 2002). The decrease in leaf relative water content could be related to low water availability under stress conditions or to root systems, which are not able to compensate for water lost by transpiration through a reduction of the absorbing surface (Gadallah 2000). Guo et al (2010) reported that mycorrhizal roots can explore more soil volume due to their extra matrical hyphae that facilitate them for absorption and translocation of more nutrients than by non-mycorrhizal plants.…”

In order to study bio fertilizers and zinc effects on some physiological parameters of triticale under a water-limitation condition, a factorial experiment was conducted based on randomized complete block design with three replications in 2014 and 2015. Experimental factors consisted of three irrigation treatments [normal irrigation (W 0 ); moderate water limitation (W 1 ) and severe water limitation (W 2 )]; four bio fertilizers' levels [(no bio fertilizer (F 0 ), application of mycorrhiza (F 1 ), plant-growth-promoting rhizobacteria (PGPR) (F 2 ) and both application PGPR and mycorrhiza (F 3 )] and four nano zinc oxide levels [(without nano zinc oxide (Zn 0 ) as control, application of 0.3 (Zn 1 ), 0.6 (Zn 2 ) and 0.9 (Zn 3 ) g L −1 )]. Results showed that water limitation decreased chlorophyll content, relative water content, stomatal conductance, quantum yield and grain yield of triticale, whereas electrical conductivity and the activity of catalase (CAT, EC 1.11.1.6), peroxidase (POD, EC 1.11.1.7) and polyphenol oxidase (PPO, EC 1.14.18.1) enzymes were increased. Inoculation of plants with bio fertilizers and zinc application improved these traits (except electrical conductivity) under water-limitation condition as well as normal irrigation. Based on the results, it was concluded that bio fertilizers and nano zinc oxide application can be recommended for profitable triticale production under water-limitation condition.ARTICLE HISTORY

“…isolates increased RWC from 5% to 16% under normal and 21.7-28.4% under stress conditions when compared to the un-inoculated control. The amelioration role of Zn in maintenance of relative water content might be attributed to improvement of vascular tissue (Gadallah 2000).…”

“…Leaf RWC reflects the metabolic activity in tissues (Flower and Ludlow 1986) and is generally declined after water stress (Table 1). Such a decrease in leaf RWC could have been due to unavailability of water in the soil (Shalhevet 1993) or root systems (Gadallah 2000).…”

Water stress treatments on some morphological, biomass, physiological, biochemical characteristics and budding success of apricot and plum cultivars/Myrobolan 29 C plum rootstock have been studied in a pot-experiment trial. Three different water stress levels (control-100 %, medium-75 %, and severe-50 % of the pot capacity) were applied. The results showed that measured morphological, biomass, physiological and biochemical characteristics as well as budding success of cultivars on the rootstocks were affected by water stress. Water stress, both moderate and severe, significantly decreased the relative shoot length, diameter and shoot stem cross sectional area, plant total fresh and dry weights. Increases in water stress led to increases in peroxidase activities, phenol and proline contents in plum rootstock. Increases in water stress also resulted in reduction in budding success in both Formosa (plum cv)/Myrobolan 29 C (90.00 % and 48.33 %) and San Castrese (apricot cv)/Myrobolan 29 C (87.50 % and 42.83 %).Key words: antioxidant enzymes, apricot, budding success, rootstock, water stress.Résumé : Les auteurs ont étudié des traitements au stress hydrique pour certains paramètres morphologiques, physiologiques et biochimiques, la biomasse et le bourgeonnement des cultivars d'abricotier et de prunier sur le prunier porte-greffe Myrobolan 29 C dans le cadre d'un essai en pot. À cette fin, ils ont appliqué trois degrés de stress hydrique (témoin-100 %, modéré-75 % et grave-50 % de la capacité du pot). Les résultats indiquent que le stress hydrique affecte les paramètres associés à la morphologie, la biomasse, la physiologie et la biochimie de même qu'au bourgeonnement des cultivars sur porte-greffe. Un stress hydrique modéré ou grave réduit de manière significative la longueur, le diamètre ainsi que la surface transversale de la tige des pousses, le poids frais de la plante et son poids sec. La hausse du stress hydrique entraîne une plus grande activité de la peroxydase, de même que la concentration de conphénol et de proline chez le prunier porte-greffe. L'augmentation du stress hydrique entraîne de surcroît une diminution respective du bourgeonnement chez le cultivar de prunier Formosa/Myrobolan 29 C (90,00 % et 48,33%) et le cultivar d'abricotier San Castrese/Myrobolan 29 C (87,50 % et 42,83 %).

“…100% subject had to highest leaf relative water content (79.22%). The reason of decrease in leaf relative water content may be that there are non-useful water in the soil or roots may not fulfill the lost water originated from the perspiration due to decrease in absorbing surface (Gadallah, 2000). Tuna et al (2010) stated that water stress decreased the leaf relative water content while Kirnak et al (2001b) stated that water stress significantly decreased leaf relative water content (LRWC) and vegetative development.…”
