Dormancy and Seed Germination in Tamarindus indica (L)
The dormancy and seed germination of Tamarindus indica (L) was studied. This involved the usage of some dormancy-releasing methods and the influence of oven dry heat treatments on the seeds. The preliminary germination tests on fresh and air-dried seeds showed low percentage germinability (10-20%). The seeds are known to have high socio-economic value most especially in the savanna regions of t...
متن کاملMethods for overcoming seed dormancy in jimsonweed (Datura stramonium L.)
This study aimed to examine dormancy-breaking of jimsonweed seeds. Seeds were collected from Hamedan. They were subjected to different treatments: (a) concentrated sulfuric acid for 1, 1.5, and 2 min; (b) hot water at 80°C and 90°C for 5 and 10 min; (c) mechanical scarification with sandpaper; (d) light exposure for 10, 20, and 30 days; and (e) fluctuating temperature (5–15°C). The highest germ...
متن کاملAbortive Seed Development in Common Bean (phaseolus Vulgaris L.)
INTRODUCTION Embryo defective mutants in Phaseolus vulgaris obtained by Ethyl methanesulfonate (EMS) induction were studied to determine the structural and molecular basis of seed abortion in this species. In the wild-type, the classical pattern of seed development showed coordinated differentiation of the embryo proper, suspensor, endosperm tissue, and seed coat. On the contrarily, EMS mutant ...
متن کاملSeed Maturation Regulators Are Related to the Control of Seed Dormancy in Wheat (Triticum aestivum L.)
In Arabidopsis, the regulation network of the seed maturation program controls the induction of seed dormancy. Wheat EST sequences showing homology with the master regulators of seed maturation, leafy cotyledon1 (LEC1), LEC2 and FUSCA3 (FUS3), were searched from databases and designated respectively as TaL1L (LEC1-LIKE), TaL2L (LEC2-LIKE), and TaFUS3. TaL1LA, TaL2LA and TaFUS3 mainly expressed ...
متن کاملSeed dormancy and germination.
Seed dormancy and germination are complex adaptive traits of higher plants that are influenced by a large number of genes and environmental factors. Studies of genetics and physiology have shown the important roles of the plant hormones abscisic acid and gibberellin in the regulation of dormancy and germination. More recently, the use of quantitative genetics and mutant approaches has allowed t...
