“…LAI is the site of photosynthetic activity; this parameter is of major importance in the selection of salt tolerant varieties and could be considered more reliable than the vegetation height (Ben Naceur et al, 2001). Our outcomes are in accord with those of El Youssfi (2013), Algosaibi et al (2015), and Stikic et al (2015). Those authors declared that increased NaCl concentration in water decreased the leaf area of quinoa and consequently decreased LAI.…”

The impact of three level of salinity (T0 = 1.2 dS m-1, T1 = 9.2 dS m-1 and T2 = 18 dS m-1) on photosynthetically active radiation intercepted (PARabs), Radiation Use Efficiency at pre-anthesis and post-anthesis (RUEPR and RUEPS), Radiation Use Efficiency of total dry biomass (RUETDM) and Radiation Use Efficiency of Grain Yield (RUEGY) at quinoa harvest were investigated during the growing season (2015). The RUE pre-anthesis (from transplanting to anthesis) has registered a decrease of 10.8 and 15.8% respectively in T1 (RUEPR = 4.62 g MJ-1) and T2 (RUEPR = 4.36 g MJ-1) compared to the control T0 (RUEPR = 5.18 g MJ-1). Likewise, the RUE post-anthesis was reduced by 8.9 and 32.1% in T1 (RUEPS = 1.23 g MJ-1) and in T2 (RUEPS = 0.91 g MJ-1), dissimilarity to T0 (RUEPS = 1.35 g MJ-1). The maximum RUETDM (3.2 g MJ-1) was manifested in (T0). However, the minimum RUETDM (2.8 g MJ-1) was observed in T2 (S = 18 dS m-1). A decline of 16.1% was observed in RUETDM due to the reduction on TDM from T0 (S = 1.2 dS m-1) to T2 (S = 18 dS m-1). As well, the RUEGY declined when salinity increased. The highest RUEGY (1.24 g MJ-1) was registered in T0. However, the lowest RUEGY (0.62 g MJ-1) was obtained in T2. A decrease of 50% in RUEGY due to the height reduction on yield was observed in the T2.

“…Drought‐induced growth inhibition was less pronounced for the roots (63%) compared to the shoots (73%), leading to an enhanced root‐to‐shoot weight ratio. Similarly, Stikić, Jovanović, Marjanović, and Dordević () found that root biomass of C. quinoa did not change significantly in response to drought as the shoot parts did. Such reaction of biomass allocation between root and shoot is considered to be an adaptive feature to sustain water uptake under decreasing water availability (Jacobsen & Stølen, ; Munns, ).…”

This study aimed to evaluate the ability of Piriformospora indica to colonize the root of Chenopodium quinoa and to verify whether this endosymbiont can improve the growth, performance and drought resistance of this species. The study delivered, for the first time, evidence for successful colonization of P. indica in quinoa. Hence, pot experiment was conducted in the greenhouse, where inoculated and non-inoculated plants were subjected to ample (40%-50% WHC) and deficit (15%-20%WHC) irrigation treatments. Drought adversely influenced the plant growth, leading to decline the total plant biomass by 74%. This was linked to an impaired photosynthetic activity (caused by lower g s and C i /C a ratio; stomatal limitation of photosynthesis) and a higher risk of ROS production (enhanced ETR/A gross ratio). P. indica colonization improved quinoa plant growth, with total biomass increased by 8% (controls) and 76% (drought-stressed plants), confirming the growth-promoting activity of P. indica. Fungal colonization seems to diminish drought-induced growth hindrance, likely, through an improved water balance, reflected by the higher leaf w w and g s .Additionally, stomatal limitation of photosynthesis was alleviated (indicated by enhanced C i /C a ratio and A net ), so that the threat of oxidative stress was minimized (decreased ETR/A gross ). These results infer that symbiosis with P. indica could negate some of the detrimental effects of drought on quinoa growth, a highly desired feature, in particular at low water availability.

“…Quinoa reacts to drought in several ways; drought avoidance by reducing the transpiration rate as a result of decreasing the stomatal conductance and by sustaining water uptake (Razzaghi et al, 2011 andStikić et al, 2015). They concluded that quinoa should be irrigated when or before the relative available water reaches 0.42.…”

multi environmental trial involving five quinoa genotypes i.e., KVL-SRA2, KVL-SRA3, Regalona, Q-37 and Q-52 was conducted along the North Western Coast of Egypt. The eight tested environments included two sites in the first season of 2014/2015 i.e. irrigated Matrouh and rainfed Matrouh, while in the second season of 2015/2016 there were six sites including three rainfed sites of Ras El Hekma, El Neguilla and Matrouh as well as an irrigated site in Matrouh with three planting dates i.e., 1 Nov.,15 Nov., and 1 Dec. Grain yield was significantly influenced by both genotypes and environments; Regalona genotype produced the highest grain yield in most of the studied environments (6 out of 8 environments) with the highest grain yield of 3.08 t/ha in irrigated Matrouh site in the first season. Moreover, it showed more drought tolerance as compared to the other genotypes. The environment effect was the major source of variation as compared to the genotype and genotype × environment interaction effects, and attributed to 88.5% of the total variation in the grain yield. Two-mode pattern analysis of the environment-standardised matrix of grain yield revealed three genotypic groups of different response pattern across environments. In general, the grain yields of the genotypes were lower under rainfed conditions as compared to irrigated conditions, except for Matrouh in the second season for the late irrigated planting dates i.e., 15 Nov. and 1Dec. The high tolerance of quinoa to drought makes it an excellent choice for the diversification of future agriculture in the North Western Coast of Egypt and other regions with similar harsh conditions.
