油橄榄中试园主栽品种佛奥及其授粉品种选配的研究

1980—1987年在湖北省武昌、宜昌、巴东和陕西省城固等地的8个县(市)进行了油橄榄丰产栽培中间试验,总面积约133.3ha。结果表明,佛奥品种在各主要中试点生长发育良好,生态适应性强,花型优越(完全花百分率高达80—95％),具有一定的自交结果能力(自交座果率1.96—2.40％),果实品质好(果肉率79.0—79.2％),含油率高(干果44.08％,干果肉71.5—73.9％),早实丰产,适合作为主栽品种。城固32、莱星同佛奥品种花期一致,授粉可配性高(正、反交座果率分别为7.13—9.35％、10.64—11.25％),作为授粉品种和佛奥搭配种植可增加油撖榄园的产量。

STUDY ON CULTIVAR FRANTOIO AND ITS POLLINATORS OF OLIVE IN INTERMEDIARY EXPERIMENT ORCHARD

Intermediary experiment of Olive cultivation has been carried out in Hubei and Shanxi Province from the year 1980-1987. The experiment orchards distributed in Wuchang, Yichang, Badong, Chenggu etc. eight counties (towns) with an area of 133.3 ha. in total lying between 33°10' -30°36' N latitude and 115°05'-107°00' E longtitude. This paper deals with the growth, bloom, fruitage, productivity, yield inconsistency of cultivar Frantoio and crossability with its pollinators Chenggu 32 and Leccion. According to the study, Frantoio which grew well in different locations is thought to be with a wide-range eco-adaptability. This cultivar has higher percentage of perfect flowers (80-95%) and normally sufficient fruit set obtained in self-pollination (1.96-2.40%). With good care, Frantoio starts bearing early and its productivity is fairly high. Its fruits has an approximately 79.0-79.2% flesh yield, while its oil content is higher than that of the others tested. Chenggu 32 and Leccion bloom coordinatelly with Frantoio and have a satisfactory fruit set (7.13-9.35%) in controlling pollination with Frantoio as pollinators, as they are planted together with Frantoio can promote grove's productivity.
