Effect of salinity on seed germination of Abelmoschus esculentus

Abstract

Salinity is one of the most common abiotic factors in the world and which strongly limits crop yields. Germination under salt stress could be a quick test to look for salt-tolerant plants. Our study was carried out on the seeds of okra (Abelmoschus esculentus L.), a mallow native to East Africa, known for its fruit used as a vegetable, rich in vitamin C and calcium. The objective of this experiment is to study the effect of salt stress on germination using NaCl at different concentrations. The seeds are germinated at a temperature of 25°C. The results obtained show that the first sprouts appear from the second day after planting seeds for the controls as for stressed seeds salinity; changing germination accelerates with decreasing salt concentration. By cons, salinity does not affect the final rate of germination but rather influences the duration of the germination by lengthening when the medium of the salt concentration increases.

Study on Okra (Abelmoschus esculentus L.) Response to Salt Stress Environment under Kabul Climatic Conditions, Afghanistan

“…Our findings also confirm the results of Ifediora, et al, (2014) and Abid et al, (2002), who observed a significant reduction in okra germination by increasing salt concentrations in irrigation water. High levels of salinity, especially NaCl can inhibit the germination rate due to toxic and osmotic effects (Miryam, Moulay, & Narimane, 2015). In this study at treatment level 20 mM, the immature deaths of some plants were observed as well.…”

“…Worldwide, the okra cultivation area exceeds one million hectares and its production is estimated at over six million tons (Basharat, 2019), in which India is known as a higher producer (Kumar, Ramjan, & Das, 2019 ;Kumari, Rai, & Das, 2019). Okra (Abelmoschus esculentus L.) is the member of Malvaceae (Sumudunie, Uluwaduge, Wijayabandara, & Premakumara, 2019) and it is Originated from Africa (Miryam, Moulay, & Narimane, 2015;Saleh et al, 2013). Currently, okra has grown widely in Tropical, Subtropical and Mediterranean regions (Sachini, Sutharsan, & Srikrishnah, 2019;Yakoubi et al, 2019;Benchasri, 2012;Abid, Malik, Khalid, & Wajid, 2002).…”

“…Germination under saline conditions may be a rabid test to explore salt tolerant plants [7]. So, the seeds were collected from a vitality genotype at North Sinai Governorate, Egypt.…”
