Biological Factors Affecting Seeds of Lentil Cultivars Stored for Planting in Jordan with Emphasis on Grain Legumes Beetles and Weevils.

摘要

Lentil seeds of five cultivars were gathered from farms stores from various sites through out Jordan in 2013 and 2014 to examine biological factors attacking the plant production. Germination, viability and purity percentages of the lentil seeds samples were evaluated by the international standards. Seed germination was ranged from 65 to 100% and seed viability was ranged from 80 to 100% depending on the lentil cultivar and the site of seed collection. The correlation between seeds germination and viability % was highly positive. The percentages of seeds purity were ranged between 80 and 99% in all lentil cultivars. Number of holes caused by the stored product insects in all seeds in the Red and Balady cultivars were significantly less than the other lentil cultivars. The most common insects species in the seeds samples of all cultivars from different parts of Jordan was Rhyzopertha dominica, followed by Bruchus rufimanus, Sitopilus granarium, Oryzaephilus surinamesis, Anthrenus museorum, A.verbasci and Cryptolestes ferrugineus and from Amman governorate was B lentis, followed by B. rufimanus, Callosobruchus maculates, B. incornatus, B. pisorum and C. chinensis. Several agricultural practices wereconcluded and suggested to get high quality lentil seeds to be planted.
