In the preceding communication' it was shown that phenylmercuric acetate sprayed upon detached leaves brings about closure of the stomata and thereby diminishes the diffusion of water from the leaves and of CO2 into the leaves. In 9 out of 11 experiments, induced closure of stomata reduced transpiration relatively more than CO2 assimilation as predicted from diffusion theory. This work led to e...
Chlormequat (cycocel or CCC), the plant growth retardant, was evaluated for its ability to control plant height in Brassica oleracea cultivar ‘Kamome White’ and ‘Nagoya Red’. Different concentrations of CCC (0, 500, 1000 and 1500 mg/L) were sprayed and drenched on plants 40 days after transplanting. Data were recorded the 60 and 90 days after transplanting. The 1500 mg/L of CCC resulted in abou...
this study investigated the potential role of age in inductive and deductive grammar learning among iranian foreign language learners. the experimental population consisted of our randomly selected samples including two groups of children (with age of exposure to english within 8-13), and two groups of adults (with age of exposure to english within 11-13). thus, the comparison was between ch...
what miller wants is a theatre of heightened consciousness. he speaks of two passions in a man, the passion to "feel" and the passion "know". he belives that we can have more of the latter. he says: drama is akin to the other inventions of man in that it ought to help us know more and not merely to spend our feelings. the writing of the crucible shows us that he is trying to give more heightene...
in order to investigate the effect of plant growth promoting rhizobacteria (pgpr) along with zinc (zn) and manganese (mn), foliar spraying on the morphological parameters of basil (ocimum basilicum l.) an experiment was conducted in factorial based on a randomized complete block design with three replications in 2011. treatments were the pgpr inoculation with azotobacter and azospirillum (azb+a...
the author intend to by studying the historical causes of the appearance of the novation in the west and explanation of its legal nature from past to present of french law, proves on the one hand that the novation does not extracted from the french civil code and in the shiite jurisprudence with quite similar terms even before the enactment of iranian civil code, was considered by the shiite su...
to determine effects of phenyl-phethalamate acid on yield and yield components of tomato, cucumber, eggplant and cabbage, this experiment was investigated in a randomized complete block design with three replications in the spring and summer of 2010. treatments included the time and number of foliar spraying with phenyl-phethalamate acid (1000 ppm). control plants were not sprayed. the first st...
In March 1990 a study was carried out in the village of Kicheba, United Republic of Tanzania, in which the pyrethroid insecticide lambda-cyhalothrin was sprayed on all the internal surfaces of houses and other shelters at a coverage of about 25 mg of active ingredient per m2. Every day for 6 days, 12 spraymen and 3 squad-leaders were interviewed about symptoms of overexposure to the insecticide...
The composting process emits various volatile chemicals, including hydrocarbons, nitrogen compounds, sulfur and oxygenated compounds. These gases must be removed to avoid atmospheric pollution. Spraying extracted materials from plants, such as tea tree oil, onto the surface of a windrow is novel odor-reduction technique for treatment gaseous emissions facilities. In this study, plant material-b...
In this research, the presence of metalaxyl residues was studied in field-grown cucumber. Two different formulations of metalaxyl were used in the experiments. In the first experiment, cucumber plants were sprayed once and repeatedly by Ridomil-MZ 72 WP at 2.5 g/litre. In the second experiment, single and double applications of metalaxyl granule 5G were carried out at 5 g/m2. Leaves and fruit...
