Several recent studies have indicated that an enriched atmosphere of carbon dioxide (CO2) could exacerbate the intensity of plant invasions within natural ecosystems, but little is known of how rising CO2 impacts the belowground characteristics of these invaded systems. In this study, we examined the effects of elevated CO2 and nitrogen (N) inputs on plant and soil microbial community character...

By the use of an immunofluorescence technique, the main source of the antigens released by the pollen grains of Phalaris tuberosa L. (Gramineae) on leaching has been shown to be the intine. The main concentration is in the thickened zone underlying the germination pore. The intine is also the site of various hydrolytic enzymes. The fate of the intine-held antigens has been followed in compatibl...

Switchgrass (Panicum virgatum L.) and reed canarygrass (Phalaris arundinacea L.) were pretreated under ambient temperature and pressure with sulfuric acid and calcium hydroxide in separate experiments. Chemical loadings from 0 to 100g (kg DM)(-1) and durations of anaerobic storage from 0 to 180days were investigated by way of a central composite design at two moisture contents (40% or 60% w.b.)...

Herbicide resistance in little seed canary grass (Phalaris minor Retz.) wheat is the major sustainability issue, which puts rice-wheat (R-W) system north-western Indo-Gangetic Plains (IGP) under serious threat. To assess level, a questionnaires based survey with systematic approach was conducted during rabi 2017-18 five districts (Yamuna Nagar, Kaithal, Karnal, Fatehabad and Rohtak) of Haryana....

Isoproturon, 3-p-cumenyl-1 dimethylurea was the only herbicide controlling Phalaris minor, a major weed growing in wheat fields till the early 1980s. Since it has acquired resistance against isoproturon, like other substituted urea herbicides, where the identified target site for isoproturon is in the photosynthetic apparatus at D1 protein of Photosystem-II (PS-II). Nucleotide sequence of susce...
