Scape bending disorder is the most important factor affecting postharvest loss of gerbera cut flowers. One of the ultimate reasons for gerbera stem bending is lignin, with deformation structural functions and defensive mechanisms. This postharvest experiment was conducted to evaluate the role of phenylalanine ammonia lyase (PAL) and peroxidase (POD) enzymes activity in stem bending of two gerbe...

Aim of this study was to evaluate the effects of diazinon toxicity (LC50) on silver carp and roach fry for measuring resistnce of these fishes. Roach with an average weight of 7 ± 1 g and silver carp 30 ± 1 g were studied to measuring lethal concentration LC50 at 96 hours. Experiment was used with a completely randomized design in 9 treatments and 3 replications for both silver carp and roach. ...

In this experiment eight 1,600 mL dual-flow continuous culture fermenters were used to measure the fermentation pattern of cultivable and pasture forages in camel. Two adult camels were used as rumen inocula donors. Fermenters were fed with 120 g of DM/d in 3 equal portions at 08:00, 16:00, and 24:00 h. The trial contained two treatments of four replicate each in a completely randomized design....

Two experiments studied the effects of canola or sunflower seed supplementation on conjugated linoleic acid (CLA) concentration in milk fat of lactating cows. In each experiment, only eight cows in early lactation were available to assign to one of two treatments in a completely randomized design and were fed individually for 12 wk. Experiment 1 compared similar diets with or without the additi...

This experiment was conducted to investigate the effects of different levels of canola oil and diet mixing time length on performance, carcass traits and blood lipids in broilers. In this experiment 288 Ross-308 broilers were used from 11 up to 42 days as factorial arrangement (3×2) included three levels of canola oil (0, 3 and 6%) and two mixing time length (10 and 15 minute) in 6 treatments, ...

In this study, Penicillium digitatum, the causes of green mould disease of orange fruits, were isolated from infected fruit in Bam city. Antifungal activity of three different plant essential oils Eucalyptus camaldulensis, Zataria multiflora, Myrtus communis at 50, 100, 150 and 200 ppm concentration, have been evaluated. MIC (minimum inhibitory concentration) and growth inhibi...
