Effect of Salinity Stress on Germination, Seedling Growth, Mineral Uptake and Chlorophyll Contents of Three Cucurbitaceae Species

Abstract

This study was performed to screen out the various species of 'Cucurbitaceae' family, musk melon (Kalash and Durga), bottle gourd (Crystal Long and Nuefield) and squash (Green Round, and Squash Malika) against the salt stress. All genotypes were treated with five different levels of NaCl (T0 = control, T1 = 1.5 dS m -1 , T2 = 3.0 dS m -1 , T3 = 4.5 dS m -1 and T4 = 6.0 dS m -1 ) and half strength of Hoagland's nutrients solution as the base nutrient solution. Results showed that the bottle gourd varieties "Nuefield" and "Crystal Long" performed best by maintaining the highest germination (93.2% and 85.6%), number of leaves per plant (4.5 and 5.7), shoot length (16.84 cm and 16.14 cm), root length (13.48 cm and 13.00 cm), plant fresh weight (942.2 g and 918.6 g), plant dry weight (118.4 g and 107.5 g), leaf area (171.2 cm 2 and 169.1 cm 2 ), chlorophyll content (3.5 μg/cm -2 and 3.4 μg/cm -2 ) with low chloride (1.57 ppm and 1.59 ppm) and sodium content (0.47 HIGHLIGHTS• Three species of Cucurbitaceae family are evaluated against the salt stress.• Higher levels of salinity have more adverse effects on the growth of cucurbits.• The varieties of bottle gourd performed well against the salt stress.

Effect of NaCl Salt Stress on Growth, Ions and Organic Solutes Contents in a Local Cultivar Kpinman of African Eggplant (Solanum macrocarpon L) in the Republic of Benin

“…These data confirmed our previous findings in the same African eggplant cultivar [11]. "The reduction of plant growth under salt stress is a common phenomenon as reported in other plant species including vegetables" [16,17,18,19]. According to [3], "the detrimental effects of salinity on plants can be osmotic in nature (reduction of water absorption by the plant after high osmotic pressure), toxic (transport and accumulation of excessive amounts of certain ions, in particular Na + in the aerial parts) or nutritional (deficiency in the absorption of certain essential ions, K + and Ca ++ in particular)".…”

Farklı melez kombinasyonları ile elde edilmiş su kabağı (Lagenaria siceraria) melezlerinin su kültürü koşullarında tuz stresine morfolojik ve fizyolojik olarak tolerans düzeylerinin belirlenmesi

“…Gövde ve kök taze-kuru ağırlıklarında olduğu gibi, tuz stresi altında, 9XA16 melezi hariç, tüm melez kombinasyonlarının yaprak sayısı ticari anaçtan daha yüksek belirlenmiştir. Naseer et al (2022) "Nuefield" ve "Crystal long" su kabağı çeşitlerinde tuz stresi altında en yüksek yaprak sayısı, sürgün uzunluğu ve kök uzunluğu, bitki taze ağırlığı ve bitki kuru ağırlığı elde etmişerdir. Tuz stresi altındaki bitkilerin köklerinin su alma potansiyelinin önemli düzeyde azaldığını, kök gelişimi ve gövde uzamasında gerilemenin olduğunu, gövde çapları ve bitki boylarının ve yaprak alanının kontrole kıyasla azaldığını bildirilmiştir (Aydın & Yetişir, 2023a).…”

From Sequencing to Genome Editing in Cucurbitaceae: Application of Modern Genomic Techniques to Enhance Plant Traits

“…Plants also experience an imbalance in ion content, with higher levels of chloride and sodium ions and lower concentrations of calcium and potassium ions. However, plants have the capacity to adapt to salinity stress by utilising biochemical pathways that maintain or promote growth through improved water or ion management [176].…”
