Net photosynthesis rate (Pn), stomatal conductance (gs) and transpiration rate (E) of anise hyssop were measured during the four cloudless days, in reference to diurnal fluctuations of leaf temperature (Tleaf), leaf vapor pressure deficit (VPD leaf) and photosynthetic photon flux density (PPFD) in well watered (WW), stressed (S) and recovered (R) plants. An analysis of measured data showed tha...

mungbean (vigna radiata (l.) wilczek) or green gram as a dryland grain legume is exposed to varied timings and severity of drought stress, resulting in variability in photoassimilate production. in order to evaluate some physiological responses in one mungbean cultivar to timing and severity of drought stress, a 3-replicate rcbd (randomized complete block design) field experiment was carried ou...

the objectives of this study were to evaluate the effects of nitrogen fertigation frequency on lint yield, lint properties, chlorophyll content (spad readings), and the photosynthesis rate (pr) of cotton. this study was carried out in the southeastern anatolia region of turkey in 2011 and 2012 with drip-irrigated cotton. the maximum lint yield (1,856 kg ha-1) was obtained with one lateral for e...

net photosynthesis rate (pn), stomatal conductance (gs) and transpiration rate (e) of anise hyssop were measured during the four cloudless days, in reference to diurnal fluctuations of leaf temperature (tleaf), leaf vapor pressure deficit (vpd leaf) and photosynthetic photon flux density (ppfd) in well watered (ww), stressed (s) and recovered (r) plants. an analysis of measured data showed that...

in order to investigate the effects of drought stress and nitrogen fertilizer on photosynthesis rate and some physiological characteristics in two barley cultivars, a pot experiment was conducted using a randomized complete block design as a factorial experiment with three factors including water stress, nitrogen fertilizer and barley cultivars in three replications. irrigation treatments condu...

it is suggested that cultivars of wheat (triticum aestivum l.) with regulated growth and development would be able to produce higher yields under water-limited conditions, which is crucial in future food production. water use efficiency (wue) is worthy of exploration in this regard. in this study, the effects of nitrogen fertilizer levels (0, 40 and 80 kg nha-1) and a plant growth retardant (ch...

since 1895 cardamom has been cultivated in the cardamom hills of western ghats, india, which form a part of global biodiversity hot spots. these tropical forests in the last couple of decades have been subjected for severe periodical shade lopping and selective felling for maximizing cardamom production. photosynthesis, transpiration, leaf temperature and leaf relative humidity was studied in r...

abstract a greenhouse experiment was conducted to study the effects of soil copper (cu) and salinity application on photosynthesis parameters, enzyme activity and anatomical structure of two pistachio cultivars. a factorial greenhouse experiment was carried out as completely randomized design with three replications. treatments consisted of four cu levels (0, 2.5, 5, and 7.5 mg kg-1soil as cuso...
