Stimulatory Effect of Hormones, Vitamin C on Growth, Yield and Some Metabolic Activities of Chenopodium quinoa Plants in Egypt

It may be came to the conclusion that best foliar use of quinoa plants with Ascorbic acid at 50 ppm, jasmonic acid at 20 ppm, gibberellic acid at 50 ppm individually at elongation stage, stimulate the development of quinoa plants through the enhancement from the biosynthesis of photosynthetic pigments enhanced yield by growing seed yield/plant seed products index in addition to carbohydrate, proteins and phenols content of quinoa seed products and therefore all last remedies enhanced quinoa seed quality and dietary value.

This research examines the actual growth, yield and certain metabolic activities of quinoa plants in response to foliar treatments with GA3 50 ppm, JA 20 ppm and Asc. 50 ppm. Plants were grown in natural clay loamy soil conditions and treated with every of the aforementioned treatments. The treated plants showedsignificant responses in most of the growth and yield characteristics (lengths of shoots and roots, number of branches/plant, number of leaves/ plant, plant biomass and weight of 1000-seed). Also, these treatments caused significant increases in the contents of photosynthetic pigments, soluble carbohydrates, soluble proteins and total phenols content. This was the case during the entire duration of time period of the experiment.
