Abstract

The purpose of this study was to investigate plant POPULATION ECOLOGY of RIBES KHORASANICUM, an ENDEMIC SPECIES to NORTH OF KHORASAN, in Hezar-Masjed mountains. The soil analyses, anatomical studies, life form, phenology, regeneration strategies, distribution in Khorasan Province and responses to environmental conditions of the plant were considered. Some plant characteristics such as cover percentage, abundance, height, number of flowers and buds, dry matter percentage of each organ and age of individuals were recorded in two patches of its distribution. The results showed that R. khorasanicum is a woody deciduous shrub with phanerophyte life form (Micro-phanerophyte with 2-8 meter tall) which contains rhizome and mainly regenerates by vegetative method. It grows in natural and non saline soils with a pH ranging from 7.3 to 7.5 dominated by lomy ones with good drainage and a high amount of N and K and low amount of P. The plant is scattered on north aspects of Hezar- Masjed mountains up to the altitude of 2400 m.a.s.1. The leaves get sunburn and fall by the high temperature and sunlight intensity. Percentage of dry weight of organs is high in aerial stems and low in the roots. Phenological studies of the species revealed that vegetative growth, appearance of leaves and flowers as well as unripe and ripe fruits were in early to late of April, early of May (for 20 days), and early of June to late of July, respectively. The dormancy of plant is in the autumn and winter. On the whole, plant POPULATION ECOLOGY of R. khorasanicum showed that it is a valuable plant in some aspects such as medicinal properties, utility of fruits, palatability to grazers, soil protection and ornamental habits. According to WCMC, the species was assigned to Vulnerable (VU) category.
