Abstract

Current study was conducted at The University of Haripur, to evaluate the effects of salinity on four brinjal cultivars Shamli, Black Nagina, Adventa 306 and Twinkle star. Experiment was laid out in CRD with two factors i.e. brinjal cultivars and salinity levels. Okra cultivars were subjected to four different levels of NaCl salinity i.e. control, 100mMol, 200mMol and 300mMol. Results revealed that brinjal cultivar Twinkle star exhibits maximum values of Fresh weight (59g) and Dry weight (8.79g), Plant height (50.66cm), Chlorophyll content (0.032mg/g), Proline content (165.08µg/g), and K+ ion concentration (54.8mg/g), under low to moderate salinity. Hence from this experiment it can be recommended that Twinkle star should be used under saline soil conditions in order to reduce toxic effects of salinity on growth of Brinjal plants.

Highlights

8325 ha with 82999 tons annual production.Brinjal (Solanum melongena L.) belongs to In Punjab, the total cultivated area of brinjal family solanaceae is most common used is about 4452 hectares having annual vegetable in Pakistan due to its unique flavor production of 54159 tons [3]
Salinity is associated with alteration in many traits, which include osmotic stress, specific ion effect, ion imbalances and nutrient deficiency, salinity affects many physiological related to plant growth and development [15]
At higher levels of salinity plants shows many physiological affects like in which most stunted growth is most common due to lack of availability of many vital nutrients which are essential for normal plant growth and development

Summary

Introduction

8325 ha with 82999 tons annual production. Brinjal (Solanum melongena L.) belongs to In Punjab, the total cultivated area of brinjal family solanaceae is most common used is about 4452 hectares having annual vegetable in Pakistan due to its unique flavor production of 54159 tons [3]. Saline soils inhibits water uptake by the plants due to osmotic stress created by excess of salt ions in soil which reduces the turgor pressure inside the cell and causes wilting. Another prominent affect of salinity is the gathering of excise toxic ions in root zone, which creates discrepancy of ions and results in ion toxicity, reduction in availability of useful ions and causes malnutrition in plants [8]. After four weeks of salt treatment whole plant from each replication were harvested to obtain the data on different physiological and biochemical parameters. Proline content To calculate proline content, samples from each replication was homogenized by using 3% sulfosalicylic acid and the solution was filtered by using filter paper [11]. The mixture was filtered with the help of filter paper and Na and K concentrations were determined with the help of flame photometer as describe by the method of [12]
