Effects of accelerated ageing on germination and establishment of vigorous young seedlings from macrobiotic seeds: case of durum wheat

Abstract

treatment of accelerated ageing of Algerian durum wheat was used in order to predict the ability to storage of six varieties widely cultivated in Algeria, Bousellam, Setefis, Megress, Ofanto, Chen’s et Saoura The results that have been obtained show that seed that have undergone ageing treatment for two days have high abilities of germination as compared to that have undergone treatment for four days, decrease of rate of  germination was more important except for two varieties, Bousellam et Setefis Difference was as fact very highly significant. A decrease highly significant of the mean number of roots was noticed for durum varieties as compared to the check, Bousselem after four days of treatment, showed the best result. Concerning the mean of shoot length, and mean root length, a decrease not significant of growth as compared to the check was observed ; the ability to grow this better for Bousselem. This last one seem show ever to be some how different to the other varieties, in this sense that germination power is more easy and translate an ability higher to conservation and to storage. Growths higher of shoots and roots and mean roots number demonstrate that.
