Abstract:
... This paper examines the barriers to adoption of Sustainable Agricultural Practices (SAPs) in smallholder coffee farming in Kenya. Previous studies identify several barriers, but there is limited research on where these barriers exist at different stages of the coffee farming operation processes i.e. nurseries for seed germination, planting, growing, and harvesting. The study seeks to examine wheth ...

Abstract:
... Seed germination is a multifaceted process, controlled by many cues, wherein phytohormones play a central role. Despite extensive studies, it remains obscure how hormonal balance and crosstalk between hormones regulate seed germination. Here we highlight new findings showing that crosstalk between jasmonates (JA) and abscisic acid (ABA) delays seed germination. ...
