Data from "Using seed respiration as a tool for calculating optimal soaking times for ‘on-farm’ seed priming of barley (Hordeum vulgare)"

Abstract

The dataset contains the results from a series of germination and seedling vigour tests for two barley cultivars subjected to different soaking times. The dataset also contains weight and seed respiration measurements during seed soaking. This data was used in the Seed Science Research paper "Using seed respiration as a tool for calculating optimal soaking times for ‘on-farm’ seed priming of barley (Hordeum vulgare)", Carrillo-Reche, Newton & Quilliam (2021). In the manuscript, we show how seed respiration principles, previously utilised for the study of seed germination, can be used as an effective tool to rapidly find cultivar- and seed quality-specific optimal seed priming duration without the need for a cumbersome series of germination assays and mini-plot trials (current practice). It provides a greater understanding of physiological events and pre-germinative process of barley seed during priming (e.g. energetic and metabolic activity), and links them to their invigorating benefits. The mechanistic of these invigorating effects, i.e. timing and contribution of their drivers, are discussed in detail against the current knowledge.
