The effect of O(2) partial pressure on the germination and the respiration of 12 cultivated species was studied. The reciprocal of the time necessary to observe rootlet emergence in 50% of the seeds was used to approach the germination rate. The maximum germination and respiration rates were reached in most seeds at O(2) pressures close to that of air. Decreasing the O(2) pressure produced a gr...

background and purpose: according to fao's report, lentil yield in iran is much lower than average yield in the world. this is due to low quality seedling production, low germination and emergence capacity, biotic and abiotic stresses and poor seedling establishment which was forced to looking for a way to enhance these components. seed priming is one of the strategy for increasing the rat...

Poor emergence resulting in inadequate stand establishment is a major problem associated with direct-seeded rice production, especially for semidwarf cultivars. In order to gain information on the problem, plant type related to gibberellic acid (GA3) and seeding depth was studied. A total of 21 cultivars including 9 semidwarfs and 12 talls had seed treated with GA3 at 25 parts per million (ppm)...
