One of the unifying theories of plant biology is that the variety of plant forms are simply different modifications of a common growth plan. Different permutations of a few key features of plant growth can generate a bewildering array of seemingly distinct forms. There is perhaps no better illustration of this than the comparison of a flower and a shoot. The idea that these two apparently diffe...

Genetic variability was studied for rhizome yield and its contributing characters among twenty seven turmeric (Curcuma longa L.) genotypes. The analysis of variation revealed significant differences the genotypes all traits viz., plant height, number tillers, primary rhizomes per plant, secondary length mother rhizome, girth weight rhizome. Turmeric variety Shobha recorded highest fresh which o...

objective: to determine the effectiveness of counseling in reducing anxiety of nulliparous pregnant women. materials and methods: in this quasi-experimental study, 110 nulliparous pregnant women were selected out of all pregnant women referring to fatemieh hospital in hamadan, iran. then, the subjects were divided into two groups in experimental and control (55 women in each). the data were col...

For several plant species, brood size results from the abortion of ovules and seeds. However, these processes have rarely been studied together in wild plants. In some of the leguminous species studied, seed abortion has been found to depend on pollen quality and on the position of the ovule or fruit. The direct consequence for the mother plant is that fruit costs increase as the seed:ovule rat...

INTRODUCTION In sexually reproducing organisms, gametes are generated by a specific lineage derived from somatic cells that undergo a somaticto-reproductive cell fate transition (SRT). In mammals, the primordial germ cells (PGCs) differentiate in the embryo at gastrulation stage (Bendel-Stenzel et al., 1998). By contrast, the spore mother cells (SMCs) of flowering plants are formed in the adult...

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 naïve seed dispersers. The hypothesis that seed coat impermeability in many tropical Fa...

In this paper we are investigating the long time behaviour of the solution of a mutation competition model of Lotka-Volterra’s type. Our main motivation comes from the analysis of the Lotka-Volterra’s competition system with mutation which simulates the demo-genetic dynamics of diverse virus in their host : dvi(t) dt = vi [
