Common reed (Phragmites australis (Cav.) Trin. ex Steud.) is distributed widely throughout the world with various ecotypes. This research compares the functional traits and biomass allocation patterns of two contrasting reed ecotypes. Twelve pairs of aquatic and terrestrial reed samples were collected in northern China. Significant differences in functional traits between the two reed ecotypes ...

In order to investigate the effect of drought and salinity stress on caper plant (Capparis spinosa), a factorial experiment including two factors consisting of drought and salinity levels based on randomized complete block design (RCBD) with five blocks were carried out at College of Agriculture, Shiraz University, Shiraz, Iran. After pretreatment, seeds were germinated in petri dishes and then...

drought is the main constraint limiting chickpea productivity which makes a considerable difference between the potential and actual yield. in order to evaluate the effect of drought stress on different morpho-physiological characteristics of chickpea, four distinct genotypes were studied in three sampling times (pre-stress, stress and recovery) with three replications. as the results implicate...

Active gibberellin (GA(1)) is an important mediator of thermoperiodic growth in pea. Plants grown under lower day than night temperature (negative DIF) elongate less and have reduced levels of GA(1) compared with plants grown at higher day than night temperature (positive DIF). By comparing the wild type (WT) and the elongated DELLA mutant la cry(s), this study has examined the effect of impair...

Suboptimal levels of phosphorus (P) strongly inhibited leaf expansion in young cotton (Gossypium hirsutum L.) plants during the daytime, but had little effect at night. The effect of P was primarily on cell expansion. Compared to plants grown on high P, plants grown on low P had lower leaf water potentials and transpiration rates, and greater diurnal fluctuations in leaf water potential. Hydrau...

in order to evaluate the effects of nitrogen fertilizer on yield, yield components and dry matter remobilization of different rice genotypes, a field experiment was carried out at the farm of ramin agricultural and natural resources university (ahwaz/iran) during 2007. experiment was arranged in a split plot based on randomized complete block design with three replications. four nitrogen fertil...

A field experiment was conducted to assess the optimum inter- and intra-row spacing on growth, yield and yield component of Roselle (Hibiscus sabdariffa L.) in 2014/15 cropping season at Wondo Genet Agricultural Research Center experimental site (at Wondo Genet station). Two inter-row spacing (60 and 90 cm) and three intra-row spacing (30, 60 and 90 cm) were evaluated using two varieties, WG-Hi...

Arbuscular mycorrhizal fungi (AMF) are able to increase root enzymatic activity of acid and alkaline phosphatases. However, the role of AMF on phosphatase activity has not been reported in papaya (Carica papaya L.), which is frequently established at places with soil phosphorus (P) deficiencies. The goals of this research were to determine the effect of Glomus claroideum (Gc), and plant growth ...
