Prunus avium L. is one of the most important temperate zone fruits in the world. Most of the cherry cultivars always have difficulties of fertilization and fruit set due to self-incompatibility, so they need suitable and compatible pollinizers for commercial fruit production. In this experiment, pollination compatibility of cherry cultivars of ‘Napoleon’, ‘Burlat’, ‘Zhan’, and ‘Lambert’ was studied as both pollen recipients and donors. To determine the compatibility or incompatibility of pollinizers, percent of fruit set was calculated. This research was carried out as a factorial experiment in a randomized complete block design. The final average fruit set in studied cultivars was different under self or cross-pollination. The results showed that ‘Napoleon’, ‘Zhan’ and ‘Lambert’ cultivars are the suitable pollinizers for ‘Burlat’. Also, ‘Burlat’ is a cultivar which produced many fruits under self-pollination. Therefore, ‘Burlat’ can be used as monoculture for orchard establishment. Results showed that cultivar ‘Napoleon’ was cross-incompatible with ‘Lambert’. ‘Zhan’, ‘Napoleon’ and ‘Lambert’ cultivars are founded self-incompatible and require cross-pollinations to obtain fruits.

Essential oils as reducing agents of cabbage peroxidase     

Seyyed Javad Mousavizadeh  Shahram Sedaghathoor  Hasan Khorami 《Scientia Horticulturae》2011

Based on the antioxidant properties of essential oils, the effect of thyme, coriander, and rosemary was evaluated on the reduction of peroxidase in white cabbage “Brassica oleraceae var.capitata f. alba” and red cabbage “B. oleraceae var. capitata f. rubra”. To do this, pure, 50, 75, 100 and 200 μl/100 ml concentrations of essential oils were applied in vivo and in vitro of cabbages. Antioxidant activity of the essential oils was compared with that of ascorbic acid. Results revealed that the highest percentage of antioxidant activity was achieved in vitro using a pure concentration of coriander (52.65%) and rosemary (54.64%), and in vivo applying thyme (60.07%) of white cabbage. Applying in vitro pure concentration of coriander (46.39%) and 50 μl/100 ml of rosemary (41.64%), and in vivo 75 μl/100 ml of thyme (42.64%) in red cabbage showed high antioxidant activity. A high reduction of peroxidase was obtained in vitro using of essential oils in red and white cabbages.  相似文献
