Storability of some Oil Seed Crops Under Two Types of Packages

Abstract

Effect of storability on germination, viability and chemical composition of sunflower (Sakha53), canola (Sero4) and sesame seeds (Shandwel3 and Giza32) was the aim of this study was contacted at the Seed Technology Research of Sakha, Agric. Res. Station, ARC, Egypt, during the period 2012-2014 years to investigate the effect of some storage conditions, i.e. storage period (6 and 18 months) and storage packages (aluminum foil and woven poly ethylene) on some seed quality parameters of some oil seed cropes. The results indicates that increasing storage period significantly reduced germination percentage, plumule length, radical length, dry seedling weight, 1000-seed weight, relative density, oil percentage, crude protein percentage, while increased electrical conductivity and acidity percentage. The highest values of germination percentage, plumule length, radical length, dry seedling weight, 1000-seed weight, relative density, oil percentage, protein percentage and the best viability characters (by decline electrical conductivity and acidity percentage were recoded by seeds stored in aluminum foil, whereas seeds stored in woven polyethylene package gave bad viability characters (by increasing electrical conductivity and acidity percentage) for sunflower, canola and sesame seeds. For the impact of sesame cultivars the results were Shandwel3 cultivar gave the highest germination percentage, plumule length, radical length, dry seedling weight, 1000-seed weight, relative density and lowest electrical conductivity value. On the other hand, Giza32 gave the highest oil percentage and lowest acidity percentage.
