The Effect Of Seed Mass On Germination, Seedling Survival And Growth In Prunus Jenkinsii Hook.F. & Thoms., Krishna Upadhaya, Harendra Nath Pandey, Pynsakhiat Law
Turkish Journal of Botany
The effect of seed mass on germination, seedling survival and growth was investigated in Prunus jenkinsii Hook.f. & Thoms. (Rosaceae), an evergreen tree species. Seed mass varied from a minimum of 0.5 g to a maximum of 2.72 g. Seed mass had a significant effect on the percentage of seeds that germinated: 28%, 41% and 42%, respectively, of light- (1.5 g), intermediate- (> 1.5 to 2 g) and heavy-weight (> 2 g) seeds germinated. After 1 year of germination, the seedlings that arose from heavy-, intermediate- and light-weight seeds showed 80%, 63% and 42% survival, respectively. Seedling vigour, expressed in …

Germination And Seedling Behaviours Of Seeds Of Peltophorum Pterocarpum D.C.Baker Ex K.Heyne Growing Under Motor Vehicle Emission, Muhammad Shafiq, Muhammad Zafar Iqbal
Turkish Journal of Botany
Motor vehicle emission showed toxic effects on seed germination and seedling growth of Peltophorum pterocarpum D.C.Baker ex K.Heyne. Germination and growth of P. pterocarpum seeds were significantly (P < 0.05) affected in the seeds collected from the polluted areas as compared to the less polluted areas. A higher percentage of decrease in seed germination was found for the seeds collected from the extremely polluted area, followed by very much polluted, polluted, and a little polluted areas as compared to the unpolluted area (control). Seedling and root lengths were also highly decreased for the seeds of the same species collected from the extremely polluted area as compared to the control. A high percentage of seedling dry weight was found for the seeds of the same species collected from the extremely polluted area (62%), followed by very much polluted area (58%), polluted area (38%), and a little polluted area (28%) as compared to the control. According to the tolerance test, seedling growth of P. pterocarpum showed the lowest percentage of tolerance in the samples collected from the extremely polluted area (53%), followed by very much polluted area (71%), polluted area (89%), and a little polluted area (92%) as compared to the campus.
