Featured Issue: Chilean Journal of Agricultural Research Vol.73 No.2

Tri-Colour Quinoa by Alpha
The Chilean Journal of Agricultural Research has recently been updated on Bioline. Here is the first of two posts on vol.73. 

This post will discuss vol.73 no.2 and next week's post will look at vol.73 no.3

This issue includes "Influence of contrasting environments in seed composition of two quinoa genotypes: nutritional and functional properties" by Miranda et al. Quinoa (Chenopodium quinoa Willd.) has recently become more popular all of the world. In Chile, quinoa is one of the most important grains with high nutritional value. This study looks at quinoa grown in different types of environments to see how the compositions of quinoa seeds change. Two types of quinoa were grown under arid (little or no rain) and cold-temperate conditions in Chile. When grown in arid climates with irrigation, two genotypes of quinoa significantly increased in grain yield, soluble dietary fibre and vitamin B3 among others. When quinoa was grown in cold-temperate climates, its seed size increased. The results showed that Vicuña, Chile, with its arid climate, could be a potential area to grow quinoa and produce quinoa genotypes.

This article also includes "
Effects of elevated air temperature on physiological characteristics of flag leaves and grain yield in rice" by Liu et al. This study also looks at the effects of air temperature and climate on a grain, but this time on rice (Oryza sativa L.) and a focus on elevated air temperature. Previous experiences have shown that elevated air temperature has a negative affect on rice, with a loss in rice grain yield. In this study, rice was planted and the effects of high air temperature were evaluated by examining protein content, seed settling rate and grain yield among other characteristics.
