“…Salinity damages of salt stress have been previously explained in temperate fruit trees. Decrease in leaf chlorophyll and water status and increment in cell membrane permeability were reported in apple (Yin et al, 2010;Aras and Eşitken, 2019a) and sweet cherry (Aras and Eşitken, 2019b). García-Legaz et al (2008) stated that salinity depressed loquat plant growth that could be attributed to decreases in CO 2 assimilation, photosynthesis and leaf gas exchange.…”

“…Salinity is a common stress in plants caused by excessive fertilization, drought and poor drainage in soils (Aras and Eşitken, 2018;Pehlivan and Güler, 2019). Many fruit trees including sweet cherry plants are known to sensitive to salt stress (Aras et al, 2019;Aras and Eşitken, 2019a). Salinity damages of salt stress have been previously explained in temperate fruit trees.…”

The responses of sweet cherry plant to salt stress and shading treatments were investigated in the study. The study was performed in a greenhouse with 1-year-old 0900 Ziraat sweet cherry cultivar grafted onto MaxMa 14 grown in 10 L pots. About 2 months after planting, salinity and shading treatments were initiated. Three levels of shading (40, 60 and 80%) were employed. 35 mM NaCl (sodium chloride) was used to expose plants to moderate salt stress. The plants were stressed during four months. Many morphological and physiological responses were assessed. Salt stress remarkably decreased plant growth and chlorophyll, anthocyanin contents and stomatal conductance. Shading treatments protected cell membranes, leaf water status and photosynthetic pigments and leaded increment in gas exchange under salinity conditions. Cell death of leaves was observed by Evans blue staining. Necrotic lesion was not observed in the leaves of control, shading with 60 and 80% plants.The results of the study showed that shading with 80% had higher protective effect on salt stress in sweet cherry.

Objective: Water and nutrients are required for plant growth and development. Transport of water and nutrients from the roots to the shoots occurs in the xylem vessel. Acetylsalicylic acid (ASA) and sodium nitroprusside (SNP) play important roles in plant growth regulation. However, limited information is known about the relationship between SNP and ASA and leaf anatomy. Therefore, the current study was performed to evaluate the hypothesis that ASA and SNP improve leaf cortex and xylem anatomy and chlorophyll biosynthesis in peach. Material and Methods: In the study, the roots of two-year-old peach (Prunus persica (L.) Batsch) cv. Rich May grafted onto GF 677 were treated with 1 mM SNP and 1 mM ASA (except control) through irrigation. One month after the treatments, many leaf histological responses and chlorophyll biosynthesis were evaluated. Results: Both treatments increased stomatal conductance compared to control. Chlorophyll biosynthesis was influenced by the treatments. SNP and ASA increased the concentrations of the chlorophyll precursors compared to control. ASA increased cortex thickness by increasing the number of cortex cell layers. Thus, ASA can affect leaf cell division. Furthermore, SNP and ASA can enhance xylem conduits width. Conclusion: Improvement in xylem conduits may help plants under stress conditions. Therefore, SNP and ASA may be used to improve nutrient and water uptake.

“…It was found that bacterial applications had a more positive effect on chlorophyll content which is one of the most important factors determining photosynthesis capacity and these results were in agreement with many similar studies (Aydın et al, 2012;Güllüce et al, 2012;Heidari et al, 2011). SPAD value reflects chlorophyll content decreases under stress conditions (Aras and Eşitken, 2019b;Aras and Keles, 2019). Akay and Kararaslan (2012) reported that mycorrhiza applications, especially in poor soils, contribute significantly to chlorophyll content in plants.…”

Raspberry, which belongs to the genus Rubus of the Rosacea family, is an important berry fruit with economical potential due to its benefits in terms of human health and wide usage area in industry. In this study, the effects of biological fertilizers (PGPR and mycorrhiza) on some chemical properties of Heritage raspberries were investigated. For this purpose, chlorophyll, anthocyanin, total phenolic content, proline, total carbohydrate levels of plant leaves were evaluated. The highest chlorophyll and anthocyanin contents were obtained from BF5 and BF4 bacterial inoculations (37.24 and 37.85 and 5.58 and 5.14, respectively). The effect of applications on total carbohydrate content was not significant. The highest phenolic and proline contents (2.94 GAE mg g-1 and 0.091 proline g-1) were obtained from BF5 treatment. The results indicated that bacterial applications were the first application in terms of the parameters examined for Heritage raspberry cultivation in the region.
