Study of potassium and sodium silicate on the morphological and chlorophyll content on the rice plant in pot experiment (Oryzasativa L.)

ABSTRACT: Silicon is one of useful element for rice growth which is very important for the plant because of it is morphological and physiological characters. In order to study the effects of silicon on the morphological and physiological characters, we placed the provided seed in a pot after sterilization. Then, we planted the seeds in pots of three piles each one consisting four seeds. We considered the effects of silicon in the case of sodium and potassium silicate at three different levels (0, 50 and 100ppm) with a repeat of three times for each experiment. This study indicated that in the tiller stage the concentration of silicon in stem and leaf tissue will increase of silicon level. Analyzing the average of seeding indicated that the increase of sodium silicate levels caused on enhancement on plant height, tiller number leaf area and total dry weight. Also, with the increase of potassium silicate levels in stem and leaf tissue, and had a positive effect on morphological characters in tiller stage. Also in flowering stage with increasing the levels of sodium and potassium silicate fertilizers the amount of chlorophyll a, b and total chlorophyll increased, that this increase is meaningful by 5%.
