The goal of sustainable intensification of agriculture in Malawi has led to the evaluation of innovative, regionally novel or under-utilized crop species. Quinoa (Chenopodium quinoa Willd.) has the potential to provide a drought tolerant, nutritious alternative to maize. We evaluated 11 diverse varieties of quinoa for their yield and agronomic performance at two locations, Bunda and Bembeke, in...

An antiserum was raised against a fusion protein containing the C-terminal half of the protein (P3) encoded by the satellite RNA of grapevine fanleaf virus (GFLV; F13 isolate) and the N-terminal portion of the CI repressor of phage lambda. This antiserum specifically recognized P3 synthesized in the in vitro wheatgerm translation system and also in infected Chenopodium quinoa plants. In these p...

Halophyte species implement a "salt-including" strategy, sequestering significant amounts of Na(+) to cell vacuoles. This requires a reduction of passive Na(+) leak from the vacuole. In this work, we used quinoa (Chenopodium quinoa) to investigate the ability of halophytes to regulate Na(+)-permeable slow-activating (SV) and fast-activating (FV) tonoplast channels, linking it with Na(+) accumul...

Aging is accompanied by changes in gastrointestinal functions. The impact of the (GI) conditions elderly on extent proteolysis and glycolysis as well calcium bioaccessibility some cooked legumes (chickpea, lentils, soya bean white bean) cereals/pseudocereals (oats, spelt quinoa) were studied. Samples digested vitro using three GI models specifically focused which oral, gastric intestinal altere...

Salinization is increasing on a global scale, decreasing average yields for most major crop plants. Investigations into salt resistance have, unfortunately, mainly been focused on conventional crops, with few studies screening the potential of available halophytes as new crops. This study has been carried out to investigate the mechanisms used by quinoa, a facultative halophytic species, in ord...

Effect of Sowing Date and Different Levels Nitrogen on Qualitative Quantitative Characteristics Quinoa (Chenopodium quinoa Willd) in Ahar

Effect of Seed Biofertilizers Inoculation on Photosynthesis Rate, Yield, and Competitiveness Ability Quinoa (Chenopodium quinoa Willd.) with Weeds

The effect of nitrogen application levels (0.16 and 0.24 g N kg(-1) soil) on seed proteins and their amino acid compositions of amaranth (Amaranthus spp.) and quinoa (Chenopodium quinoa Willd) was studied. Total proteins of amaranth and quinoa had high contents of lysine (6.3-8.2 g 100 g(-1) protein) but low contents of methionine (1.2-1.8 g 100 g(-1) protein). Seed proteins were fractionated o...

BACKGROUND Andean indigenous crops such as quinoa (Chenopodium quinoa), kiwicha (Amaranthus caudatus) and kañiwa (Chenopodium pallidicaule) seeds are good sources of minerals (calcium and iron). Little is known, however, about mineral bioavailability in these grains. Thus the aim of the present study was to determine the iron, calcium and zinc potential availability in raw, roasted and boiled q...
