salicylic acid (sa) is considered to be plant signal molecule that plays a key role in plant growth, development, and defense responses. the physiological mechanism of exogenous sa to affect the senescence of cut lisianthus flowers during vase life was investigated. fresh cut lisianthus flowers were treated with distilled water (control), 0.5, 1 and 2 mm sa and then held at 25◦c up to 12 days. ...

the aim of this study was to compare the effects of using different levels of royal jelly in semen extender on viatal characteristics of goat sperm after freezing. semen was collected from four adult bucks twice a week and samples pooled together. sperm samples (six repeats) containing royal jelly in four levels (0.5, 1, 1.5 and 2%) had been frozen. after semen samples freezing – were thawed an...

Membrane processes are used for drinking water production and medical applications to remove and/or produce viruses using organic membranes. It appears that backwashing is not sufficient all the stopped by membrane. The use of “one-shot” membranes or chlorinated solution filtration can be considered with an additional cost accelerated aging respectively. inactivation bacteria, spores has been d...
