partitioning of photoassimilates between the sinks is one of the most important physiological processes related to the yield of crops which are affected by drought stress. therefore, the effect of drought stress in flowering and grain filling stages, on the percentage partitioning of photoassimilates among different organs was studied in 14 rapeseed cultivars in a split plot experiment based on...
Seasonal changes in carbon and nitrogen compound concentrations in a Quercus petraea chronosequence.
Forest productivity declines with tree age. This decline may be due to changes in metabolic functions, resource availability and/or changes in resource allocation (between growth, reproduction and storage) with tree age. Carbon and nitrogen remobilization/storage processes are key to tree growth and survival. However, studies of the effects of tree age on these processes are scarce and have not...
After cessation of hindlimb immobilization, which resulted in a 27-37% loss in soleus mass, the atrophied soleus muscle of young but not old rats regrows to its mass before treatment. We hypothesized that during remobilization the mRNA levels of growth potentiating factor(s) would be present in the soleus muscle of young (3- to 4-mo-old) but absent in old (30- to 31-mo-old) Fischer 344 x Brown ...
Wheat leaf senescence is a developmental process that involves expressional changes in thousands of genes ultimately impact grain protein content (GPC), yield (GY), and nitrogen use efficiency. The onset rate are strongly influenced by plant hormones environmental factors e.g. availability. At maturity, decrease uptake could enhance N remobilization from leaves stem to grain, eventually leading...
In order to study the effects of different levels of irrigation, nitrogen and plant population on yield, yield components and reserved dry matter remobilization of seed corn (SC. 704 hybrid) a research was conducted at the experimental field in Khuzestan Natural Resources and Agricultural Science University in summer, 2004. This research was made based on three split-plot field experiments, R...
