Different Drought-Tolerant Mechanisms in Quinoa (Chenopodium quinoa Willd.) and Djulis (Chenopodium formosanum Koidz.) Based on Physiological Analysis

The purpose of this experiment is to study the effects of treatment with 90% (28.5% volumetric water content (VWC)), 75% (24% VWC), 50% (16% VWC), and 25% (8% VWC) of water requirements on the growth of two djulis (Chenopodium formosana Koidz) varieties (red: RP and yellow: OR) an...

The results showed that drought stress (8% VWC) significantly reduced plant growth and relative water content, and increased H<sub>2</sub>O<sub>2</sub> and MDA content in <i>C. formosana</i> and <i>C. quinoa</i>. The most significant increase in these parameters was detected in the OR variety. The antioxidant enzymes, such as SOD, APX, and GR activities of PI variety under drought treatment (8% VWC), are significantly increased, while GR activity of <i>C. formosana</i> also increased significantly. Additionally, <i>C. formosana</i> and PI variety remained at a stable AsA/DHA ratio, but the GSH/GSSG ratio decreased during drought treatment. Moreover, drought stress increased total soluble sugars and proline content in the PI variety. However, <i>C. formosana</i> proline content was extremely significantly enhanced, and only the OR variety increased the total soluble sugar content at the same time during the vegetative growth period. In summary, <i>C. formosana</i> and <i>C. quinoa</i> have different drought tolerance mechanisms to adapt to being cultivated and produced under severe drought conditions.Pin-Hua LinYun-Yang ChaoMDPI AGarticledrought tolerance mechanismantioxidant capacityoxidative stressosmotic regulationyieldBotanyQK1-989ENPlants, Vol 10, Iss 2279, p 2279 (2021)
