“…Thus, grafting technology has recently emerged as a potential and alternative approach to the comparatively sluggish conventional breeding procedures for increasing tolerance to abiotic stressors, soil pathogens, and improving production and quality features in fruit vegetables. Grafting has been used commercially on watermelons, muskmelon, cucumbers, tomatoes, sweet peppers, and eggplants to increase plant tolerance to a variety of abiotic conditions, such as soil salinity, drought, waterlogging, high or low temperatures, and heavy metal toxicity, as well as to increase vegetable crop output and quality characteristics (Bahadur et al, 2024) . Generally, all rootstocks improved fruit quality traits.…”

Grafted seedlings has become important agricultural practice in many parts of the world for the production and protection of cucurbitaceous crops from biotic and abiotic stress. Salinity is one of the major abiotic stresses which cause reduction in the growth and productivity of cucumber in Egypt. This study aims to investigate the performance of commercial greenhouse cucumber hybrid (Hesham) grafted onto some genotypes and F1 hybrids rootstocks under salinity stress conditions (Salinity of the experimental soil and irrigation water were about 70.9 and 2.77 dS/m, respectively), at El-Anwar Farm, Cairo-Alexandria Desert Road, during summer seasons of 2020 and 2021under shade house conditions. This experiment was done in a randomized complete block design with 3 replicates. The experiment contained fourteen treatments, consisted of six genotypes rootstocks in additions to 7 F1 hybrid rootstocks compared to ungrafted control. The results indicated that grafting cucumber onto all rootstocks gave a significant improve of plant height, leaves area, fruit weight, fruit length, fruit diameter, yield and photosynthesis in both seasons, compared to non-grafted one, whereas grafted cucumber onto Kalabsha, Lagenaria siceraria PI 554556, C. maxima, C. moschata, Kalabsha x PI 534556 and Lagenaria siceraria PI 554556 x Lagenaria siceraria PI 491365 rootstocks had larger internode length than non-grafted plants in the first season. The highest values of carbohydrates content in fruits were noticed when cucumber grafted onto C. maxima x C. moschata rootstock in both seasons, whereas the highest proline content were estimated in cucumber leaves that grafted onto kalabsha rootstock in both seasons.

Biochemical and physiological processes serve as key indicators for assessing the adverse effects of biotic and abiotic stressors in plants. Due to the limited and incomplete information on the growth, root morphology, and physiology of watermelon lines under cold stress in Korea, this study aimed to evaluate selected cold-tolerant lines (PI254744, SW20, and SW66) and cold-sensitive lines (PI525233 and SW54). The evaluation was based on root and shoot weight, root and shoot length, root morphology, photosynthetic pigments (chlorophyll a, chlorophyll b, total chlorophyll, and carotenoids), and levels of proline, malondialdehyde (MDA), and soluble sugars in root and leaf samples collected at various time points. Two treatments were conducted: one at 28 °C as a control and one at 10 °C to simulate cold stress. The results revealed a decline in growth variables under cold stress compared to the control across all lines. However, the disintegration of root cellular structures and reduction in growth variables were less severe in the tolerant watermelon lines than in the sensitive ones. Under cold stress, proline, MDA, and soluble sugar levels increased in all watermelon lines relative to the control. Notably, the tolerant lines displayed elevated proline and soluble sugar levels, while the sensitive lines had higher MDA content. Furthermore, photosynthetic pigment levels were generally lower in all lines during cold treatment compared to the control, though the reduction was less pronounced in the tolerant lines than in the sensitive ones. A significant positive correlation was found between the percentage reduction in total chlorophyll content and the percentage reduction in growth variables. The lesser reduction in photosynthetic pigments, combined with higher levels of osmoprotectants (proline and soluble sugars) and lower MDA levels in the tolerant lines during cold stress, may suggest underlying mechanisms that warrant further biochemical and molecular studies to better understand cold resistance.

The use of saline water under drought conditions is critical for sustainable agricultural development in arid regions. Biochar is used as a soil amendment to enhance soil properties such as water-holding capacity and the source of nutrition elements of plants. Thus, the research was carried out to assess the impact of biochar treatment on the morphological and physiological characteristics and production of Solanum lycopersicum in greenhouses exposed to drought and saline stresses. The study was structured as a three-factorial in split-split-plot design. There were 16 treatments across three variables: (i) water quality, with freshwater and saline water, with electrical conductivities of 0.9 and 2.4 dS m− 1, respectively; (ii) irrigation level, with 40%, 60%, 80%, and 100% of total evapotranspiration (ETC); (iii) and biochar application, with the addition of biochar at a 3% dosage by (w/w) (BC3%), and a control (BC0%). The findings demonstrated that salt and water deficiency hurt physiological, morphological, and yield characteristics. Conversely, the biochar addition enhanced all characteristics. Growth-related parameters, such as plant height, stem diameter, leaf area, and dry and wet weight, and leaf gas exchange attributes, such rate of transpiration and photosynthesis, conductivity, as well as leaf relative water content were decreased by drought and salt stresses, especially when the irrigation was 60% ETc or 40% ETc. The biochar addition resulted in a substantial enhancement in vegetative growth-related parameters, physiological characteristics, efficiency of water use, yield, as well as reduced proline levels. Tomato yield enhanced by 4%, 16%, 8%, and 3% when irrigation with freshwater at different levels of water deficit (100% ETc, 80% ETc, 60% ETc, and 40% ETc) than control (BC0%). Overall, the use of biochar (3%) combined with freshwater shows the potential to enhance morpho-physiological characteristics, support the development of tomato plants, and improve yield with higher WUE in semi-arid and arid areas.
