The use of brackish waters is an alternative for the cultivation fruit-bearing plants in semi-arid regions; nonetheless, sweetsop trees (Annona squamosa L.) are sensitive to these types waters. However, phosphate fertilization can be a technique used mitigate harmful effects salinity. Thus, our objective was evaluate application phosphorus salinity irrigation water. experiment conducted randomi...

in order to evaluate of morphological, physiological and biochemical traits, related to drought tolerance, an experiment was carried out in field condition. in this study two commercial cultivars (mcc361, mcc358), three kabuli and three deci type of tolerant genotypes (mcc392, mcc537, mcc696, mcc873, mcc870, mcc10,) and three kabuli and three deci type of susceptible genotypes (mcc759, mcc588, ...

In the present study, we compared the effect of leaf age at one development stage on the photosynthetic behavior of a T-DNA-tagged allele of the ppt1 mutant. Chlorophyll fluorescence (Fv/Fm, where Fm is the maximum fluorescence yield and Fv is variable fluorescence) and fluorescence decay kinetics of the ppt1 mutant were different in leaves of different ages. The steady state levels of thylakoi...

in order to investigate the physiological and morphological traits of seven autumn sugar beet (beta vulgaris l.) cultivars (jolge, palma, giada, monotunno, sbsi1, suprema and pp8), under  freezing stress, a study was carried out as a factorial experiment (7×10) based on randomized complete block design with three replications in college of agriculture of ferdowsi university of mashhad. the plan...

In recent years, temperate bamboo species have been introduced in Europe not only as an ornamental plant, but also as a new biomass crop. To measure adaptation stress of bamboo to the climate of Western Europe, chlorophyll fluorescence was measured on a diurnal and seasonal basis in Ballyboughal, Co. Dublin, Ireland. Measurements were attained on the leaves of each node of Phyllostachys humilis...

Photoinhibition was examined in four co-occurring Mediterranean evergreen tree species during two consecutive winters. In response to low temperatures and saturating light, Juniperus phoenicea L., Pinus halepensis Mill., Quercus coccifera L. and Q. ilex ssp. ballota (Desf.) Samp. exhibited marked chronic photoinhibition, indicated by low predawn maximal photochemical efficiency of photosystem I...

The evaluation of photosynthetic characteristics plants is important for the success rate germplasm introduction. To select grape varieties with higher adaptability and trait performance, this experiment aimed at evaluating comparing indices, chlorophyll fluorescence parameters, pigment content, leaf five Chinese hybrid varieties. results showed that under high light intensity stress, growth ‘R...

We wounded Pocillopora verrucosa to simulate injury caused by fish corallivores, and then evaluated impacts of this damage on coral performance under different temperatures (26.6 and 29.6°C) and flow speeds (6 and 21 cm s–1) in microcosms. Colony growth (weight), photosynthetic efficiency (maximum dark-adapted quantum yield of PSII, Fv/Fm [where PSII is Photosystem II, Fv variable fluorescence ...

The C3 plants are frequently suffering from exposure to high temperature stress which limits the growth and yield of these plants. This study seeks to clarify the physiological mechanisms of heat tolerance in relation to oxidative stress in C3 species. Fifteen C3 species were exposed to prolonged moderately high temperature stress 36/30°C for 40 days in a growth chamber. Chlorophyll fluorescenc...
