present study was conducted to consider the effects of different concentrations of 2,4-d and ba on somatic embryogenesis induction, development and maturation of three strawberry cultivars (kurdistan, parose and camarosa). for this purpose, leaf blade, nodal, petiole, stamen and flower bud calli were cultured on murashige and skoog (ms) medium supplemented with 2, 4 dichlorophenoxyacetic acid (...

Mediterranean greenhouses for cultivation of Phalaenopsis orchids reproduce the warm, humid, and shaded environment of tropical underbrush. Heating represents the highest production cost, due to the high thermal requirements and the long unproductive phase of juvenility, in which plants attain the critical size for flowering. Our researches aimed to investigate the effect of plant size, tempera...

Tabernaemontana rotensis (Kaneh.) P.T. Li is an attractive small tree that endemic to the islands of Guam and Rota. Conservation efforts threatened population are constrained by lack research. Understanding ecology flower fruit development fundamental successful conservation angiosperms. This study determined extent induction following tropical cyclone defoliation, tested efficacy 10% urea spra...

The PIN family of trans-membrane proteins mediates auxin efflux throughout the plant and during various phases of plant development. In Arabidopsis thaliana, the PIN family comprised of 8 members, divided into "short" and "long" PINs according to the length of the hydrophilic domain of the protein. Based on sequence homology using the recently published potato genome sequence (Solanum tuberosum...

In tropical dry forests most plants are deciduous during the dry season and flush leaves with the onset of the rains. In Costa Rica, the only species displaying the opposite pattern is Bonellia nervosa. To determine if seasonal changes in light availability are associated with the leaf and reproductive phenology of this species, we monitored leaf production, survival, and life span, as well as ...
