Abstract:
Agriculture has been being affected by environmental stresses such as drought, salinity, extreme temperatures, chemical toxicity and oxidative stress which reduce crop yield fifty percent, approximately and water stress that is caused by salinity and drought is a prevalent problem in the world. Salinity stress is one of the most important abiotic stress factors that limit crop production in arid and semi-arid regions. Salinity negatively affects plant growth when salts accumulate in the root zone of the plants. Castor is a hardy crop which survives in a wide ecological range. Basically castor grows throughout the warm-temperate and tropical regions and flourishes under varieties of climatic conditions. Castor is naturally a long-day plant, but it is adaptable with fewer yields to a wide range of photoperiods. The present research was conducted to analyze the comparative effects of sodium chloride and calcium chloride and their combined effect on the Riccinus communis. In this research, I focused on the comparative effects of sodium and calcium chloride on the morpho-anatomical characters of plant Riccinus communis and their structural adaptations against salinity. Seeds were collected and trial was established from April to May in Botany Department, The Islamia University of Bahawalpur. The plants were kept in full sunlight and irrigated daily. Five different levels of sodium chloride and calcium chloride and their synergistic effect were used in the present trial, 3 to 4 replicates in each row .i.e. control (NaCl, CaCl2 and their combined effect), 50mM, 100mM, 200mM, 400mM respectively with the interval of 10 days. The experiment was planned in a completely randomized design (CRD) with one control and four level treatments of NaCl and CaCl2 respectively. Effect of salinity on Morphological and anatomical parameters concluded that the castor plant (Riccinus communis L.) is tolerant of salinity and the growth and development of castor plants are affected by high salinity as plant is tolerant and develop adaptations against salinity. Calcium generally plays the role of nutrient for plants and reduces the effect of salinity on the morpho-anatomical characters of plants. The significant effects were observed at 200mM and 400mM. The Riccinus communis does not cope with these high salinity levels and was affected. The Riccinus communis is an important crop medicinally and commercially. It may contribute to Pakistan’s economy and it has significant tolerant capacity to face the extreme salinity.
