Parasitism in flowering plants has evolved at least 11 times [1]. Only one family, Orobanchaceae, comprises all major nutritional types of parasites: facultative, hemiparasitic (partially photosynthetic), and holoparasitic (nonphotosynthetic) [2]. Additionally, the family includes Lindenbergia, a nonparasitic genus sister to all parasitic Orobanchaceae [3-6]. Parasitic Orobanchaceae include spe...

OBJECTIVE To investigate the antioxidant, antimicrobial, antiplasmodial, acute toxicity and haemolytic activities of methanolic extracts of three plants. Phytochemical analysis to determine the phenolic contents was also carried out. METHODS The 2,2-diphenyl-1-picryl-hydrazyl (DPPH) free radical scavenging, NCCLS broth microdilution and Plasmodium Lactate Dehydrogenase (pLDH) assays were used...

6 The ability to develop invasive haustoria is the key feature of parasitic angiosperms. 7 The haustorium attaches the parasite to the host, penetrates the host while keeping 8 its own tissues intact, develops a vascular continuity between the host and parasite 9 and ultimately provides the conduit through which host and parasite materials flow. 10 The ability to make haustoria distinguishes pa...

in this study salix aegyptica hydrolat based carbonated drinks were formulated. differents ratio of salix aegyptica hydrolat (egyption willow water) mixed with carbonated water, citric acid and sugar to adjust the final drink to 10-12 brix and desirable acidity. sensory properties of the products were evaluated at a ranking test by a trained panelists for choosing the best formulation. evaluati...

i (1) We investigated interactions between snowshoe hares (Lepus americanus) and their food plants in winter during a cyclic fluctuation in numbers at Kluane, Yukon, between 1977 and 1985. • (2) The winter diet of hares at Kluane was dominated by four species of shrubs and trees. Betula glandulosa, the most preferred species, was common on only four of nine study plots. Salix glauca was eaten m...

Differences in soil and habitat conditions, depending on the type of soil on which shrubby species of willow Salix L. are being grown for energy purposes, are reflected in weed infestation species diversity and the distinctiveness of these crops, and require an individual program of control and reduction of the abundance of competitive herbaceous vegetation. Our study aimed at determining soil ...

Twigs of Salix species are candidates for cryopreservation procedures because they become tolerant of freezing temperatures during mid-winter. We examined several variables in developing a two-step cryopreservation procedure for sections from these twigs. Samples of Salix triandra cooled to -30 or -35 degree C and then transferred to the vapor phase over liquid nitrogen gave the greatest percen...

• Germination and symbiotic development of the myco-heterotrophic plant Monotropa hypopitys were studied by sequential recovery of packets of seed buried in dune slacks in relation to distance from mature M. hypopitys and presence and absence of shoots of its autotrophic coassociate Salix repens . • Fungal associates of M. hypopitys growing under S. repens in the dune slacks, and under S. capre...

Alpine ecosystems are seriously threatened by climate change. One of the key mechanisms by which plants can adapt to changing environmental conditions is through evolutionary change. However, we still know little about the evolutionary potential in wild populations of long-lived alpine plants. Here, we investigated heritabilities of phenological traits, leaf size, and performance traits in natu...

Salix caprea is widely used in folk medicine for rheumatoid arthritis, malaria, various hemorrhages, gout, neuralgia and intestinal diseases as an antipyretic, analgesic, anti-inflammatory, antibacterial, hemostatic, sedative, and antihelminthic agent However, There are no critical reports available about anti diabetic potential of Salix caprea flowers. So anti diabetic effect of methanol extra...
