چکیده
Quinoa is one of the most nutritious grains and currently has attention due to its adaptation a wide range environments abiotic stresses. This study was conducted under field conditions an arid agro-ecosystem evaluate response physiological yield nineteen elite quinoa genotypes grown three water regimes (95, 65, 35% Field capacity) using drip system in sandy soil. The experiment design split-plot randomized complete block during 2019/20 2020/21 growing seasons. results showed significant differences among evaluated genotypes, treatments, their interaction. Fluorescence chlorophyll components were sensitive stress strongly decreased at low soil moisture.

متن کاملYield and water use efficiency of early potato grown under different irrigation regimes
Potato grown for early or off-season production plays a crucial role in the economy of several areas in the Mediterranean countries. Irrigation is important for determining yield and earliness, thus a better investigation of plant response under various pedo-climatic conditions can help to improve resource use efficiency and farmer income. A two-year field research (2009-2010) was carried o...
متن کاملThe Worldwide Potential for Quinoa (Chenopodium quinoa Willd.)
Quinoa is a highly nutritious food product, being cultivated for several thousands years in South America, with an outstanding protein quality and a high content of a range of vitamins and minerals. Other positive aspects of quinoa are the saponins found in the seed hull and the lack of gluten. Quinoa is one of the main food crops in the Andean mountains, but during recent times there has been ...
متن کاملDistribution of minerals in quinoa (Chenopodium quinoa Willd.) seeds.
The distribution of minerals in quinoa (Chenopodium quinoa Willd.) seed was examined using energy dispersive X-ray microanalysis (EDX) in combination with scanning electron microscopy (SEM). Phosphorus, K, and Mg coincided in localization in embryonic tissue. Since phytin globoids have been known to localize in protein bodies in embryonic cells of quinoa seed, it is thought that P is attributed...
