Effect of Salt Stress in Different Stages of Growth on Qualitative and Quantitative Characteristics of Cumin (Cuminum Cyminum L.)

Abstract

ABSTRACT. Cumin (Cuminum cyminum L.) is one of the most important pharmaceutical plants. As a considerable portion of existing agricultural lands in arid regions is exposed to aridity and finally to salinity, we need to study the effects of salinity on the growth and production of agronomical products. For this purpose, an agricultural experiment in the form of split plots with three replications was conducted in 2011 at the Islamic Azad University, Gonabad Branch, Iran, in the longitude of 58°, 50', latitude of 34°, 54', and altitude of 940 m from the sea level. At the main plot, four salinity levels (2,5,8 and 11ds/m) and at the sub plot, the growth stages of stress implementation (including stress in establishment, flowering, and seed filling stage), were located at random. The results showed that the salinity rate had significant impact on fresh weight, dry weight, height , percentage of essence, seed and biological yield. With the increase in salinity from 2 to 11ds/m, a significant decrease in all vegetative and reproductive characteristics were observed. The most sensitive growth stages of plant to salt stress, during vegetative and reproductive period were the stage of establishment and flowering, respectively. There was no interaction between the growth stage of plant and salinity rate, except for seed yield and harvest index.

RETRACTED ARTICLE: Salinity-induced changes in the morphology and major mineral nutrient composition of purslane (Portulaca oleracea L.) accessions

“…Both of the common purslane varieties were the most affected accessions compared to the ornamental accessions. Very highly significant reductions in the number of flowers in Cumin ( Cuminum cyminum L.) have been reported by Hassanzadehdelouei et al, [ 27 ] at 11 dS m −1 salinity. In wheat ( Triticum aestivum ), high reductions in the numbers of spikelets have also been described by Ranjbar [ 44 ] at 20 dS m −1 salinity.…”

Physio-Biochemical Composition and Untargeted Metabolomics of Cumin (Cuminum cyminum L.) Make It Promising Functional Food and Help in Mitigating Salinity Stress

“…Cumin is an important medicinal and spice crop cultivated in the arid and semi-arid regions of the world, where saline soil is widely distributed, unsuitable for agriculture [ 12 ]. Plant is good source of minerals like iron, copper, zinc and manganese and B-complex vitamins such as thiamine, niacin, riboflavin and antioxidant vitamins like A, E and C [ 47 ].…”

“…Cumin is salt sensitive plant and its growth is drastically reduced with increasing salinity stress [ 11 ]. Physiologically, cumin plant has ability to tolerate 5 dS m -1 of salt in irrigated water but its seed productivity is significantly reduced by 55% [ 11 – 12 ].…”

Irrigation Management for Higher Productivity in Seed Spices-A Review

“…Cumin is tolerant to saline water irrigation and it is reported that maximum salinity tolerance for economical cumin yield is 5.0 dS.m -1 and the most sensitive stage of growth to salt water stress in the vegetative and reproductive stages are establishment and the flowering stage (Hassanzadehdelouei et al, 2013).…”
