A new smut fungus, Urocystis phalaridis, is described on Phalaris sp. (Poaceae) from Iran.

Three new species of parasitic wasps (Braconidae: Microgastrinae) from southern India are described and illustrated. Glyptapanteles clanisae sp. nov., a remarkable gregarious endoparasitoid, was bred from the caterpillar of Clanis phalaris Cramer (Lepidoptera: Sphingidae) on the host plant Pongamia pinnata (L.) (Leguminosae) along with a hyperparasitoid, Eurytoma sp. (Eurytomidae). Glyptapantel...

Sites with indicators of hydrologic disturbance had lower species rich...

citrus blast is one of the important diseases of citrus in north of iran. the disease causes considerable damage during and immediately after the cold seasons. the causal agents have epiphytic survival on diverse weeds during spring and summer. during 2009-2010, samples were collected from several candidate weed plants including: poa annua, phalaris canariensis, sorghum halepense, cynodon dacty...

Paper has been made from grasses and other non-wood materials for over 1900 years. Wood is a relatively new papermaking fibre, only 100 years old. Today the commercial non-wood pulp production accounts for 6% of the global pulp production. The main source for the raw material is plants of the Gramineae family. Research on nonwood material has concentrated on grasses like Miscanthus, Phalaris, S...

Karyotype characteristics can provide valuable information on genome evolution and speciation, in particular in taxa with varying basic chromosome numbers and ploidy levels. Due to its worldwide distribution, remarkable variability in morphological traits and the fact that ploidy change plays a key role in its evolution, the canary grass genus Phalaris (Poaceae) is an excellent study system to ...

We assessed the biomass production, biomass allocation patterns, height growth, and root airspace of seventeen wetland plant taxa, including two potentially invasive species, grown under high nutrient conditions and subjected to four hydrologic regimes: constant drawdown, cyclic flooding and drawdown, cyclic flooding and drought, and constant flooding for the duration of the experiment ( 10 wee...

to investigate the factors affecting the population density of weeds and yield loss of them in wheat, a non systematic survey experiment was conducted in 45 fields in the township of bandar-gaz (sarmahaleh village) in 2012. sampling of wheat and weeds were taken in two stages (heading and harvest maturity) by randomized to the five points of each field using quadrate size 1m*1m. in this study a...

In a feeding trial with 24 sheep, we used the alkanes, long-chain alcohols (LCOH) or both of these plant wax markers, to estimate the diet composition of animals offered diets comprising alkane-labelled cottonseed meal (CSM) together with up to four forages. The diets used were: Diet 1 subterranean clover (Trifolium subterraneum); Diet 2 subterranean clover + phalaris (Phalaris aquatica); Diet ...
