adverse environmental storage conditions including high temperature and relative humidity could affect seed quality. the objective of this investigation was to quantify relationship between temperatures and seed moisture on seed deterioration and determination viability constants in sorghum. four storage temperatures (5, 15, 25 and 35oc) and three moister content levels (6, 10 and 14%) were use...

Extended Abstract Introduction: Pulses are among the best sources of plant protein and important components of crop rotation, which in recent years, have been considered one of the major options for plant research. Seed storage is one of the important traits in legume breeding. Storage temperature, seed moisture content, and storage duration are the most important factors affecting seed qualit...
