Observations of nonuniform photosynthesis across leaves cast doubt on internal CO(2) partial pressures (p(i)) calculated on the assumption of uniformity and can lead to incorrect conclusions about the stomatal control of photosynthesis. The problem can be avoided by measuring p(i) directly because the assumptions of uniformity are not necessary. We therefore developed a method that allowed p(i)...

in order to evaluate the effect of using zinc granulated phosphorous biofertilizer on yield and yield components of white bean (phaseolus vulgaris l.), a field experiment based on a randomized complete block design with three replications was performed. experimental treatment were included of using phosphate and triple super phosphorous chemical fertilizer at five levels (without using of chemi...

Activities of the sucrose-cleaving enzymes, acid and neutral invertase and sucrose synthase, were measured in pods and seeds of developing snap bean (Phaseolus vulguris L.) fruits, and compared with t4C-import, elongation and dry weight accumulation. During the first 10d postanthesis, pods elongated rapidly with pod dry weight increase lagging behind by several days. The temporal patterns of ac...

The learning difficulties of Down Syndrome students are often related to limitation of their short term memory. They have constraints in separating the information received by the brain. This leads to difficulties in reading process. Therefore, they fail to focus when learning. Scaffolding is a systematic assistance used to ease the burden of the short term memory of the Down Syndrome students....
