Abstract: Hydrogen sulphide (H2S) is emerging as an important gaseous molecule involved in various plant developmental processes and plant stress responses. In this study, exogenous H2S donor (sodium hydrosulfide, NaHS) treated wheat plants were used to investigate the role of H2S in response to iron-deficiency. The results showed that H2S significantly alleviated leaf chlorosis under iron-deficient conditions, and thus improved photosynthesis. Moreover, H2S increased the lateral root (LR) number, density and length of wheat seedlings grown in iron-sufficient and deficient culture solution, and promoted phytosiderophores (PSs) secretion from roots simultaneously, which eventually led to an increase in iron uptake. Taken together, these results indicate that H2S improved iron uptake by regulating root development and PSs secretion, and consequently increased chlorophyll biosynthesis and photosynthesis in plants under iron-deficiency.

Abstract: The Maneh-Semelghan county of North Khorasan province because of climate diversity and topography has a very diverse and valuable vegetation reserves that constitutes a high percentage of medicinal plants. Due to people familiar with medicinal plants, many of these plants are known by local names and people are in widespread use in traditional medicine. During a survey that was conducted for 5 years in the years 2010 till 2014, 123 species of medicinal plants belonging to 32 plant families, from different parts of the county were collected and identified. Profile identified species include the scientific name of the species, family, life form, Chorotype and applied parts of collected species were recorded in forms. Based on the results of this study, the family of Asteraceae with 20 species of medicinal plants accounted for the largest number of species. Then the family of Lamiaceae with 18 species of medicinal plants had the most species. Rosaceae and Apiaceae families with 12 and 13 species respectively were next in line.

Abstract: An experiment was conducted at Sher-e-Bangla Agricultural University, Bangladesh to evaluate the efficacy of different fungicides against major foliar diseases of rice, namely brown spot (Bipolarisoryzae), blast (Pyriculariagrisea), narrow brown leaf spot (Cercosporaoryzae) and sheath rot (Sarocladiumoryzae). Nine fungicides such as Knowin 50 WP 0.2%, Score 250 EC 0.1%, Control 15 EC 0.1%, Proud 25 EC 0.1%, Tilt 250 EC 0.2%, Folicure 250 EW 0.1%, Sunvit 50 WP 0.7%, Cupravit 50 WP 0.7% and Bordeaux Mixture (CuSO4 2.27g: CuO 2.27g: H2O 100ml) were sprayed at maximum tillering stage to control the diseases. All fungicides were effective in reducing the incidence of aforesaid diseases at flowering, milking, dough and maturity stages. The effect of Tilt 250 EC 0.2% (Propiconazole) and Proud 25 EC 0.1% (Propiconazole) were better than the other fungicides in controlling those diseases, resulted higher yield. In maturity stage, the highest disease severity of brown spot and sheath rot were found in the control (untreated) while the lowest severity was observed in Tilt 250 EC 0.2%. Proud 25 EC 0.1% also showed the lowest severity of blast and narrow brown spot at maturity stage. The highest grain yield (4.75t ha-1) was recorded at treatment, Tilt 250 EC 0.2%. Therefore, Tilt 250 EC 0.2% and Proud 25 EC 0.1% can be recommended to control the foliar diseases of rice which help to increase the grain yield of that crop.

Abstract: Frafra potato (Solenostemon rotundifolius) is a herbaceous specie of the family of Lamiaceae. It is cultivated in the tropical regions of Asia and Africa, mainly by the small holder farmers, as a subsistence tuber crop. It is one of the neglected species with potential for commercialization. In Burkina Faso, Ouagadougou is known to be an important city of consumption of frafra potato. Previous research activities have revealed that profits made from marketing of frafra potato is decreasing compared to that of other tuber crops (yams, sweet potato). The objective of this study was to identify the marketing potentialities and constraints for frafra potato. Ten traders of frafra potato’s tubers of three main markets in Ouagadougou were interviewed in 2015. They recognized the increasing demand for frafra potato tubers and its high economical potential. The frafra potato variety with black skin color were identified to be the preferred variety. However, the rapid tuber deterioration and the lack of efficient methods of storage, the small size of tuber and the short period of tubers availability on the markets were identified to be the main constraints of frafra potato marketing. These constraints should be addressed by future research programs.

Abstract: Based on the investigation of weed in warm season turf of 46 Golf courses in southern China during 1998-2000 and 2013-2015 respectively. 159 kinds of weed were determined. Most of weed population or community contained 20 kinds of element weed including Digitaria sanguinalis, Paspalum conjugatum, Axonpus compressus, Panicum repens, Poa annua; Cyperus rotundus, Kyllinga brevifolia; Hydrocotyle sibthorpioides, Oxalis corniculata, Kummerowia striata, Alternanthera philoxeroides, Desmodium triflorum, Mimosa pudica, Centella asiatica, Securinega suffiruticosa, Viola japonica, Hedyotis corymbosa, Euphorbia humifusa, Lobelia chinensis and Alysicarpus vaginalis in 2000. While it changed to new 20 kinds of element weed including Digitaria ischaemum, Digitaria sanguinalis, Poa annua, Brachiaria villosa, Axonpus compressus, Cynodon dactylon, Paspalum distichum, Eragrostis pilosa, Panicum repens, Dactyloctenium aegyptium; Kyllinga brevifolia, Cyperus rotundus; Euphorbia humifusa, Hedyotis corymbosa, Desmodium triflorum, Hydrocotyle sibthorpioides, Centella asiatica, Alysicarpus vaginalis, Kummerowia striata and Trifolium repens in 2015. The investigation showed that grasses were increasing rapidly, broadleaf weeds were decreasing comparing with the weeds 15 years ago in the same golf courses. The paper showed 24 pieces of picture related those population or community. Author also analyzed the possible factors to influence the evolution of weed population. It may due to hand weeding, competition, climate changing, improper maintain and improper herbicide application.
