Netherlands: Wageningen University & Research investigates salt stress in quinoa

Tridge summary

Researchers at the WUR Laboratory for Plant Breeding in the Netherlands Plant Eco-phenotyping Center have discovered that two quinoa varieties, Pasto and selRiobamba, have different strategies for dealing with salt stress. The Pasto variety conserves water, limiting its uptake and growth, while selRiobamba is more aggressive in absorbing water. This finding is crucial for plant breeders in the development of new salt-tolerant crops, as salinization of agricultural land is on the rise worldwide.

The researchers took measurements of, among other things, the transpiration of the plants every three minutes for eleven weeks. The quinoa variety Pasto developed a conservation strategy, whereby the plant limited water uptake and growth. The second species, selRiobamba, on the other hand, developed a greedy strategy to absorb as much water as possible and achieve growth despite the salt stress. 'The outcome of this research is important for plant breeders who want to develop new salt-tolerant crops,' says Viviana Jaramillo Roman of WUR in Frontiers in Plant Sciences. 'Salinization of agricultural land is increasing worldwide. Salt tolerance is a complex trait involving multiple genes. They are now more clearly visible.' Netherlands Plant ...
