Abstract

A pot experiment was carried out to study the effect of salinity stress on seeds germination and plants growth of Coriander (Coriandrum sativum L.)by the selection method. For this purpose, four treatments of different concentrations of NaCl were used, namely, 0, 1000, 2000, 3000, and 4000 ppm of NaCl. The following parameters of: seeds germination, roots number and length, plant strength, number of leaves, plant length, shoot tip necrosis, and the percentage of survivals were recorded. The Obtained results showed that all growth parameters were reduced by increasing the NaCl concentration except for the percentage of shoot tip necrosis which was increased with a significant difference among all treatments. Coriander plants were found to resist salinity up to the concentration of 3000 ppm NaCl only.

Highlights

Coriander (Coriandrum sativum) which belongs to family Apiaceae (Umbelliferae), is a herb which possesses nutritional and medicinal properties, besides, it is one of the most commonly used spices
Increasing NaCl concentration leads to more reduction in seeds germination percentage and plant growth rate, it leads to a decreasing in the percentage of survivals
While the percentages of shoot tip necrosis is increased by the increase of NaCl concentration

Summary

Introduction

Coriander (Coriandrum sativum) which belongs to family Apiaceae (Umbelliferae), is a herb which possesses nutritional and medicinal properties, besides, it is one of the most commonly used spices. The first medicinal uses of the plant were reported by the ancient Egyptians. Both leaves and seeds of the plant are used for medicinal purpose. Coriander contains many active principles primarily monoterpenes, & pinene, limpene, ý-terpinene, p-Cymene, borenol, Citronellol, camphor, geraniol, coriandrin, dihydrocoriandrin, coriandrons A-E, flavonoids, and essential oils. Coriandrum sativum has been reported to have several pharmacological effects such as antifertility, antihyperglycemic, antihyperlipidemic, antioxidant, antiproliferative, hypotensive, and digestive stimulant. It helps to remove toxic mineral residue, such as mercury and lead and excretes them in the urine or faces, (Leena et al, 2012)
