Treatment with aqueous toluene-ethanol has been shown to induce "pore" formation in plant cell membranes. The evidence is as follows: [List: see text]While the principal experimental material was roots of Atriplex nummularia Lindl., the fact that similar results were also observed with leaves of Pisum sativum L. and with the alga Chlorella pyrenoidosa Chik. suggests that the phenomenon is gener...

BACKGROUND AND AIMS The heterocarpic species Atriplex tatarica produces two types of seeds. In this study, how basic population genetic parameters correlate with seed germinability under various experimental conditions was tested. METHODS Population genetic diversity was ascertained in eight populations of A. tatarica by assessing patterns of variation at nine allozyme loci. Germinability of ...

Atriplex lentiformis plants collected from coastal and desert habitats exhibit marked differences in capacity to adjust photosynthetic response to changes in growth temperature. Plants from desert habitats grown at 43 C day/30 C night temperatures had higher CO(2) uptake rates at high temperatures but reduced rates at low temperatures as compared to plants grown at 23 C day/18 C night temperatu...

Soil properties and the ability to sustain agricultural production are seriously impaired by salinity. The cultivation of halophytes is seen as a solution cope with problem. In this framework, greenhouse pot experiment was set up assess salinity response in perennial C4 species Atriplex halimus, following three cultivars annual C3 hortensis: green, red, scarlet. four genotypes were grown for 35...

India is one of the richest floristic regions of the world and has been a source of plants and their products since antiquity and man uses them in different ways according to his needs, particularly as food or as medicine. Tecoma undulata is a popular medicinal plant has long been used in ayurvedic system of medicine. The plant has been found to exhibit diverse pharmacological activities. The p...

—Wind-pollinated dioecious plants often exhibit spatial segregation of the sexes. This partial niche separation has most often been explored using abiotic niche axes. However, if the sexes are truly separated in space, then they are apt to encounter different plant species that may heavily affect growth and reproduction. Also, to the extent that their niches differ, the sexes may respond differ...

The importance of tuco-tucos (Ctenomys eremophilus) and cavies (Microcavia australis) as herbivores in the Monte Desert was assessed on a creosotebush community dominated by Larrea cuneifolia. Herbivory by tuco-tucos or cavies affected 35% of the total plants. The most highly damaged plant species was Atriplex lampa, followed by Larrea cuneifolia and Lycium sp. The level of damage caused by Cte...
