We studied the response of Elaeagnus rhamnoides (Sea Buckthorn) to drought stress in a nursery. Photosynthesis and chlorophyll content under drought were change rather modest. Growth and physiological differences in response to drought were compared between four Sea Buckthorn seedlings treatments inhabited in the Qazvin provenance origin seeds in Mashhad city of Iran. The experimental design in...

Aims—To determine the eYcacy of probing in the initial treatment of epiphora and the symptom free period in adults with blocked nasolacrimal ducts. Methods—The results of probing in 85 eyes with epiphora due to nasolacrimal duct obstruction were studied retrospectively after a mean follow up of 7.4 months (SD 11.6) by a questionnaire and interview survey of patients. Results—35% of the eyes had...

A balanced two-factor ANOVA yields a highly significant effect of watering treatment (F = 10.55, df = 1, 24, P = 0.003) and nonsignificant effects of source (F = 0.47, df = 2, 24, P = 0.628) and the watering treatment x source interaction (F = 0.05, df = 2, 24, P = 0.955). There is one low outlier, and one of the treatment groups (Heeia fresh) had substantially less variation than the others, b...

The effect of simulated rainfall frequency on the pathogenicity of Pratylenchus zeae and P. brachyurus was studied in four greenhouse experiments. Corn and grain sorghum were watered at different intervals during predetermined cycles to create a gradient of water-stressed plants. Each experiment included nematode and uninoculated treatments. Growth reaction of plants to different frequencies of...

While the responses of photosynthesis to water stress have been widely studied, acclimation to sustained water stress and recovery after re-watering is poorly understood. In particular, the factors limiting photosynthesis under these conditions, and their possible interactions with other environmental conditions, are unknown. To assess these issues, changes of photosynthetic CO(2) assimilation ...

in order to study the role of photosynthetic tissues on grain filling and remobilization of stem reserves under terminal drought, a pot experiment as semi-field was conducted as two-factor factorial in complete randomized design with three replicates at research farm of agriculture college of vali – e – asr university of rafsanjan during january to june 2012 . first factor was source strength r...
