The present study investigated the effects of supplemental foliar nitrogen (N), phosphorous (P) and potassium (K) spray, alone or in various combinations, on physiological processes and nutrients uptake in wheat under water deficit conditions. The study comprised of two phases; during the first phase, ten local wheat (Triticum aestivum L.) genotypes were evaluated for their response to PEG-6000...
Potato late blight, caused by the oomycete phytopathogen Phytophthora infestans, is a devastating disease found in potato-growing regions worldwide. Long-term management strategies to control late blight include the incorporation of host resistance to predominant strains. However, due to rapid genetic changes within pathogen populations, rapid and recurring identification and integration of nov...
We examined the adjustment of leaf angle (L theta) and foliar chlorophyll and xanthophyll chemistry in Eucalyptus nitens (Deane and Maiden) Maiden seedlings maintained in various nitrogen (N)-supply treatments over a 6-month period. Adjustment of L theta toward the vertical was greatest under conditions of foliar N deficiency and became incrementally more horizontal with increasing foliar N con...
Scaling relationships among photosynthetic rate, foliar nutrient concentration, and leaf mass per unit area (LMA) have been observed for a broad range of plants. Leaf traits of the carnivorous pitcher plant Darlingtonia californica, endemic to southern Oregon and northern California, USA, differ substantially from the predictions of these general scaling relationships; net photosynthetic rates ...
the presented study aimed at investigating the effect of foliar application of amino acids and nano particles and chelated iron on photosynthetic pigments and yield of potato. to this end a factorial experiment was carried out in the form of randomized complete block design with three replications in 2013, in the research field of natural resources institute in damavand, iran. the first factor ...
a randomized complete block design with three replications was performed in rice research institute of iran, rasht in 2008, to find the effect of supplement foliar application of nitrogen and potassium on ’daylam‘ hybrid rice grain yield, its components and grain protein percentage. foliar application of 20 kg nitrogen (5 percent n) and 15 kg potassium (3 percent k2o) in different pre-anthesis ...
Host plant resistance is an important component to the management of potato late blight, Phytophthora infestans (Mont.) de Bary. Assessment of potato lines (Solarium tuberosum L.) with various levels of resistance to P. infestans (US8, A2 genotype) were evaluated in field trials, greenhouse controlled environment chambers and inoculated tuber reactions. Five lines (AWN86514-2, B0692-4, B0718-3,...
Net photosynthesis (Pn) of loblolly pine (Pinus taeda L.) foliage was monitored monthly in 14 yr old stands under near-ambient conditions over an entire year in upper and lower crowns and in both nonfertilized stands and stands receiving nutrient amendments for six consecutive years. Air temperature, humidity, vapor pressure deficit (VPD), photosynthetic photon flux density (PPFD), and plant wa...
A large proportion of rainfall in dryland ecosystems is intercepted by plant foliage and is generally assumed to evaporate to the atmosphere or drip onto the soil surface without being absorbed. We demonstrate foliar absorption of intercepted rainfall in a widely distributed, continental dryland, woody-plant genus: Juniperus. We observed substantial improvement in plant water status, exceeding ...
The objectives of this study were to determine whether foliar application of a chlorophyll precursor, 5-aminolevulinic acid (ALA), could mitigate salinity stress damages in perennial grass species by regulating photosynthetic activities, ion content, antioxidant metabolism, or metabolite accumulation. A salinity-sensitive perennial grass species, creeping bentgrass (Agrostis stolonifera), was i...
