PART OF A HIGHLIGHT SECTION ON SEEDS Dormancy as exaptation to protect mimetic seeds against deterioration before dispersal
†Background and Aims Mimetic seeds simulate the appearance of fleshy fruits and arilled seeds without producing nutritive tissues as a reward for seed dispersers. In this strategy of seed dispersal, seeds may remain attached to the mother plant for long periods after maturity, increasing their availability to naı̈ve seed dispersers. The hypothesis that seed coat impermeability in many tropical F...

متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Dormancy-breaking requirements of Sophora tomentosa and Erythrina speciosa (Fabaceae) seeds.
The physical dormancy of seeds has been poorly studied in species from tropical forests, such as the Atlantic Forest. This study aimed to examine the effect of moderate alternating temperatures on breaking the physical dormancy of seeds, the morphoanatomy and histochemistry of seed coats, and to locate the structure/region responsible for water entrance into the seed, after breaking the physica...
متن کاملErythrinan alkaloids from seeds of Erythrina velutina.
Four new Erythrinan alkaloids (1-4) were isolated from the seeds of Erythrina velutina. The structures of these new compounds 1-4 were elucidated by spectroscopic methods including 2D-NMR. Three of four were found to be novel sulfated Erythrinan alkaloids.
