background & aim: in sustainable agriculture, organic fertilizers are considered as important alternatives for chemical ones and are of great importance in organic producing of medicinal plants. this study was conducted to study the effects of organic fertilizers on cassia angustifolia vahl in dry and subtropical climate.  experimental: this study was carried out in jiroft region, kerman (i...

The application of Pb inhibited the development of mycelia of the saprobe fungi Fusarium concolor and Trichoderma koningii and the hyphal length of the arbuscular mycorrhizal fungi (AM) Glomus mosseae and G. deserticola in vitro. The application to soil of 1500mg kg−1 of Pb decreases the dry weight, total N, P, Mg and Fe concentration and chlorophyll content of the shoot of E. globulus no inocu...

Naturally-occurring variation in K(+) concentrations between plant genotypes is potentially exploitable in a number of ways, including altering the relationship between K(+) accumulation and growth, enhancing salinity resistance, or improving forage quality. However, achieving these requires greater insight into the genetic basis of the variation in tissue K(+) concentrations. To this end, K(+)...

The application of PGPB to agriculture is increasing as it offers an alternative to the use of chemical fertilizers, pesticides and other supplements. Maize (Zea mays L.) is one of the world’s principal cereal crops, grown for grain, silage and biofuel. Nitrogen fertilizer constitutes one of the major costs in maize production, and PGPB poses a potential alternative for achieving more sustainab...

the use of in vitro potato shoot cultures for protoplast isolation is desirable for consistent protoplast qualities. ethylene build-up in the culture vessels causes problems for leaf growth (e.g. decreasing leaf surface, dry weight and chlorophyll) in shoot culture. fifty to one hundred µm silver thiosulfate (sts) produced a larger leaf area as a source of plant material for protoplast isolatio...

Peppermint (Mentha piperita L.) is one of the most important plants producing essential oil. An experiment was carried out using a randomized complete block design with 3 replications to study the effect of salinity stress on growth parameters, essential oil percent of peppermint. 4 levels of salinity solution containing 0, 50, 100 and 200 mmol NaCl was applied in irrigation plantings ...

environmental stress, particularly drought stress can play an important role in reducing plant growth especially during the germination stage in arid and semi-arid regions in iran. for cultivation of medicinal plants in arid and semi-arid areas, the assessment of their tolerance is very important. in this research, in order to evaluate the effects of salicylic acid pretreatment on enhancement o...

Strong seedling vigor is desirable trait in dry direct-seeded rice (DSR) for enhancing crop establishment and the ability to compete against weeds. A set of 253 BC3F4 lines derived from cross between Swarna and Moroberekan was phenotyped for early vigor (EV) and 8 related traits viz., early uniform emergence (EUE), shoot length (SHL), stem length (SL), shoot fresh weight (SFW), total fresh weig...
