Effective Pollination Period in Almond Cultivars

Effective pollination period for ‘Manzanillo’ and ‘Picual’ olive trees

The effective pollination periods (EPP) for ‘Manzanillo’ and ‘Picual’ olive trees have been determined in two consecutive years in irrigated orchards in California and Spain. The duration of the EPP was variable between year and cultivar. Fruit set declined gradually in response to sequential cross-pollination. Consistent differences with respect to the maximum levels of initial fruit set occur...

Ecology and Economics of Using Native Managed Bees for Almond Pollination.

Native managed bees can improve crop pollination, but a general framework for evaluating the associated economic costs and benefits has not been developed. We conducted a cost-benefit analysis to assess how managing blue orchard bees (Osmia lignaria Say [Hymenoptera: Megachildae]) alongside honey bees (Apis mellifera Linnaeus [Hymenoptera: Apidae]) can affect profits for almond growers in Calif...

evaluation of stigma receptivity period in several peach cultivars through controlled pollination under field and laboratory condition

in order to study stigma receptivity in peach cultivars : (‘makhmali’, ‘anjiri-ye-tabestane’, ‘anjiri-ye maleki’, ‘haj-kazemi’ and ’zoodras’) controlled pollination was done in both field and laboratory conditions. before pollination trials the in vitro germination of the pollen was tested in petridish. branches with adequate number of flowers were chosen for controlled pollination. self pollin...
