“…The NO triggers xylem formation through programmed cell death (Yu et al, 2014). Some studies showed that NO is involved in xylem formation in buds and xylem improvement in leaves (Aras, 2022b;2022c). In the current study we examined xylem conduit diameter of leaf midrib.…”

Salinity exhibits many constraints in vegetable growing. Exogenous applications should be performed in growing in order to mitigate salinity damage. This study examined some physiological and histological properties of young pepper (Capsicum annuum L.) 'Çetinel' plants exposed to salt stress by applying different doses of sodium nitroprusside (SNP). Seedlings were transplanted into pots and salt application was started after 6 d. One day before salt stress, three different doses of SNP (12.5, 25.0 and 50.0 μM) were applied as a solution to the roots, excluding control and salt (NaCl) application. Then, 150 mM salinity was applied to all plants except the control. The experiment was terminated 35 d after the salinity treatment. At the end of the study, many histological and physiological parameters were evaluated. Plant growth, leaf relative water content (LRWC), total chlorophyll and carotenoid content of the leaves decreased in pepper plants under saline conditions, but SNP treatments increased the values. Membrane permeability in NaCl application increased by approximately 304% compared to control application. The SNP treatments increased xylem conduit diameter by 65.7% and epidermis thickness by 61.5% compared to salinity stress. When the results were evaluated, the values closest to the control in many parameters were recorded in the NaCl+SNP 25.0 µM application and it was found that it was effective in mitigating salinity stress damage. At the same time, 25.0 µM SNP application improved xylem vessels and cortical cells that may help plants acquire water and minerals more efficiently.

“…Studies have been conducted in many plant species to determine the effectiveness of SNP under salt stress (Khoshbakht et al, 2018;Shams et al, 2019;Jabeen et al, 2021). Moreover, SNP provided early xylem formation in peach bud (Aras, 2022c) and xylem improvement (Aras, 2022b).…”

Temperate trees are subjected to a quiescent state during autumn and winter called dormancy. During buds growth, xylogenesis was observed between buds and shoots to maintain water and nutrients. In the present study, the effect of sodium nitroprusside (SNP) and acetylsalicylic acid (ASA) on peach (Prunus persica (L.) Batsch, 'J. H. Hale') flower bud phenological stages and xylogenesis between buds and shoots was investigated. Shoots were collected during the leaf fall from peach trees grafted onto the Garnem rootstock (P. dulcis × P. persica), wrapped in a damp cloth, and stored at 4 ± 1°C temperature for 850 h. After the chilling treatment, the shoots were placed for a month in a controlled chamber with environmental conditions of 21°C temperature, 65% relative humidity, and 16/8 h photoperiod. Five days after the chilling treatment (DACT), the shoots were treated with SNP and ASA, except the control. During the experiment, SNP and ASA treatments provided earliness in the stages of flower bud development. Xylogenesis was observed in all treatments starting with 11 DACT. In this stage, xylem observation was found more clearly in using SNP and ASA compared to the control. The results of the experiment showed that using SNP and ASA provides earliness in flowering via increasing xylogenesis between buds and shoots.

Plant growth promoting rhizobacteria (PGPR) represent promotes plant growth by increasing the supply or availability of nutrients to the host plant. These bacterial applications are environmentally friendly techniques and their use has become widespread recently. Some PGPRs can increase nitrogen (N) fixation and have phosphate (P) solubilizing property. In the current study, we evaluated the synergistic effects of some useful bacteria and sodium nitroprusside (SNP, a nitric oxide donor) in pepper plant. Nitric oxide (NO) acts as a signal molecule in plants and has important role in plant-bacteria symbiosis interaction. Three PGPR strains namely, Enterobacter cloacae (ZE-2), Pseudomonas putida (ZE-12) and Acinetobacter calcoaceticus (ZE-13) were used and the bacteria possess phosphorous-solubilizing and nitrogen-fixing properties. The applications of PGPRs alone and with combination of SNP (0.1 mM) were performed to the plant rhizosphere (the roots) through irrigation two times with two weeks interval starting with seedling planting. End of the study, many morphological parameters including stem diameter, plant height and biomass were improved by all applications compared to control. Root:shoot dry weight ratio decreased by the applications. Stem diameter, plant height and biomass were significantly increased with all treatments compared to control. The yield was found higher in all applications compared to control and the highest increase in the yield was provided by Enterobacter cloacae (ZE-2) application. Dry matter allocation in upper part of the plants provided higher plant yield. The applications significantly affected cell expansion and division. SNP increased the effect of Acinetobacter calcoaceticus (ZE-13) bacteria on cell division in leaf cells and midrib size. Furthermore, Pseudomonas putida (ZE-12) increased the yield combining with SNP compared to alone use. The increase in the plant growth is related with the midrib size. The application of PGPR with SNP could be a promising approach in plant growing.
