ABSTRACT The research was conducted in the 2017 and 2019 seasons in two different orchards (Bouka and Sarabion), province of Latakia, Syria, in order to identify the optimal pollinizer for ‘Dermlali’ olive cultivar. Fruit set with/without emasculation of flowers after self-, open-, and cross-pollination was studied. ‘Khoderi,’ ‘Picholine Languedoc,’, and ‘Frantoio’ were used as pollinizers in Bouka, while ‘Picholine Languedoc’ and ‘Khoderi’ were used in Sarabion. Pistil abortion and the average number of flowers per inflorescence were also studied. Results showed that ‘Dermlali’ was characterized by a low number of flowers per inflorescence (12.6–11.4 in Bouka and 11.1–9.4 flower/inflorescence in Sarabion in 2017 and 2019, respectively), and low pistil abortion percentage (10.3–19.6% as an average of the 2017 and 2019 seasons in Bouka, and Sarabion, respectively). ‘Dermlali’ was highly self-incompatible in Bouka (ISI = 0–0.06), but partially self-incompatible in Sarabion (ISI = 0.42–0.50). In both study orchards, the highest final fruit set of ‘Dermlali’ was observed after cross-pollination with ‘Picholine Languedoc.’ Significantly lower final fruit sets of ‘Dermlali’ were observed after cross-pollination with ‘Frantoio’ in both orchards. Based on the recent-discovered diallelic self-incompatibility system in olive and compatibility relationships of ‘Dermlali’ (♀) with ‘Picholine Languedoc’ and ‘Frantoio,’ the S-genotype of ‘Dermlali’ would be S1S1. Overall results suggest that planting ‘Picholine Languedoc’ as pollinizer in ‘Dermlali’ olive orchards could significantly improve fruit set and yield.

确定叙利亚海岸条件下“Dermali”橄榄品种的最佳授粉者

摘要 该研究于 2017 年和 2019 年在叙利亚拉塔基亚省的两个不同果园（Bouka 和 Sarabion）进行，目的是确定 'Dermali' 橄榄品种的最佳授粉媒介。研究了自花授粉、开放授粉和异花授粉后有/没有花去雄的坐果情况。'Khoderi'、'Picholine Languedoc' 和'Frantoio' 在布卡被用作授粉媒介，而'Picholine Languedoc' 和'Khoderi' 被用于Sarabion。还研究了雌蕊败育和每个花序的平均花数。结果表明，'Dermlali' 的特点是每个花序的花数较少（2017 年和 2019 年，Bouka 为 12.6-11.4，Sarabion 为 11.1-9.4 个花/花序），并且雌蕊败育率低（10.3-19.6% 为布卡 2017 和 2019 赛季的平均值，和萨拉比恩，分别）。'Dermali' 在布卡（ISI = 0-0.06）中高度自不相容，但在 Sarabion 中部分自不相容（ISI = 0.42-0.50）。在两个研究果园中，在与 'Picholine Languedoc' 异花授粉后，观察到最高的 'Dermali' 最终坐果。在两个果园中与 'Frantoio' 异花授粉后，观察到 'Dermali' 的最终坐果显着降低。基于最近发现的橄榄双等位基因自交不亲和系统以及'Dermali' (♀) 与'Picholine Languedoc' 和'Frantoio' 的相容性关系，'Dermali' 的S 基因型将是S1S1。总体结果表明，在 'Dermali' 橄榄园种植 'Picholine Languedoc' 作为授粉剂可以显着提高坐果率和产量。但在 Sarabion 中部分自不相容（ISI = 0.42-0.50）。在两个研究果园中，在与 'Picholine Languedoc' 异花授粉后，观察到最高的 'Dermali' 最终坐果。在两个果园中与 'Frantoio' 异花授粉后，观察到 'Dermali' 的最终坐果显着降低。基于最近发现的橄榄双等位基因自交不亲和系统以及'Dermali' (♀) 与'Picholine Languedoc' 和'Frantoio' 的相容性关系，'Dermali' 的S 基因型将是S1S1。总体结果表明，在 'Dermali' 橄榄园种植 'Picholine Languedoc' 作为授粉剂可以显着提高坐果率和产量。但在 Sarabion 中部分自不相容（ISI = 0.42-0.50）。在两个研究果园中，在与 'Picholine Languedoc' 异花授粉后，观察到最高的 'Dermali' 最终坐果。在两个果园中与 'Frantoio' 异花授粉后，观察到 'Dermali' 的最终坐果显着降低。基于最近发现的橄榄双等位基因自交不亲和系统以及'Dermali' (♀) 与'Picholine Languedoc' 和'Frantoio' 的相容性关系，'Dermali' 的S 基因型将是S1S1。总体结果表明，在 'Dermali' 橄榄园种植 'Picholine Languedoc' 作为授粉剂可以显着提高坐果率和产量。在与 'Picholine Languedoc' 异花授粉后，观察到最高的 'Dermali' 最终坐果。在两个果园中与 'Frantoio' 异花授粉后，观察到 'Dermali' 的最终坐果显着降低。基于最近发现的橄榄双等位基因自交不亲和系统以及'Dermali' (♀) 与'Picholine Languedoc' 和'Frantoio' 的相容性关系，'Dermali' 的S 基因型将是S1S1。总体结果表明，在 'Dermali' 橄榄园种植 'Picholine Languedoc' 作为授粉剂可以显着提高坐果率和产量。在与 'Picholine Languedoc' 异花授粉后，观察到最高的 'Dermali' 最终坐果。在两个果园中与 'Frantoio' 异花授粉后，观察到 'Dermali' 的最终坐果显着降低。基于最近发现的橄榄双等位基因自交不亲和系统以及'Dermali' (♀) 与'Picholine Languedoc' 和'Frantoio' 的相容性关系，'Dermali' 的S 基因型将是S1S1。总体结果表明，在 'Dermali' 橄榄园种植 'Picholine Languedoc' 作为授粉剂可以显着提高坐果率和产量。基于最近发现的橄榄双等位基因自交不亲和系统以及'Dermali' (♀) 与'Picholine Languedoc' 和'Frantoio' 的相容性关系，'Dermali' 的S 基因型将是S1S1。总体结果表明，在 'Dermali' 橄榄园种植 'Picholine Languedoc' 作为授粉剂可以显着提高坐果率和产量。根据最近发现的橄榄双等位基因自交不亲和系统以及'Dermali' (♀) 与'Picholine Languedoc' 和'Frantoio' 的相容性关系，'Dermali' 的S 基因型将是S1S1。总体结果表明，在 'Dermali' 橄榄园种植 'Picholine Languedoc' 作为授粉剂可以显着提高坐果率和产量。
