Abstract

Pollination is a key factor in the production of highbush blueberry (Vaccinium corymbosum L.) to achieve a quantitatively and qualitatively satisfactory yield. Lower yields and small fruit without commercial value are correlated with poor pollination. This study was performed to investigate the flowering phenophase and pollen performance in vitro and in vivo of five cultivars (‘Duke’, ‘Reka’, ‘Bluecrop’, ‘Nui’ and ‘Ozarkblue’) that are commercially important in Serbia. Each cultivar was used as polleniser, while ‘Reka’, ‘Bluecrop’ and ‘Ozarkblue’ were also used as pollinated cultivars. Including the self- and open-pollination variants, a total of 18 combinations were investigated during the 3‑year study period. The studied blueberry cultivars flowered during the last third of April and the first half of May and, with the exception of ‘Ozarkblue’, had a satisfactory overlap in the flowering phenophase. There were genotype, year, and genotype × year interaction effects on pollen performance in vitro of the investigated blueberry cultivars. The pollination variant influenced pollen performance in vivo: The open-pollination variant was the most favourable in all tested cultivars, followed by the cross-pollination variant, with the exception of cultivar ‘Nui’ used as a polleniser, which showed worse results compared to the self-pollination variant. In addition, the pollinated cultivar impacted the pollen performance of pollenisers, while the impact of air temperature during the flowering phenophase can only be considered in the context of the responses for each male–female combination.

授粉变异和温度对一些高丛蓝莓(Vaccinium coyimbosum L.)栽培品种繁殖行为的影响
授粉是高丛蓝莓(Vaccinium corymbosum L.)产量和质量均令人满意的关键因素。产量低、果实小且无商业价值与授粉不良有关。本研究旨在调查在塞尔维亚具有重要商业价值的五个栽培品种('Duke'、'Reka'、'Bluecrop'、'Nui'和'Ozarkblue')的体外和体内开花表相和花粉性能。每个品种都被用作授粉品种,而'Reka'、'Bluecrop'和'Ozarkblue'也被用作授粉品种。包括自花授粉和开放授粉变体在内,在为期 3 年的研究期间共调查了 18 种组合。所研究的蓝莓栽培品种在 4 月下旬和 5 月上中旬开花,除 "Ozarkblue "外,其他栽培品种的花期都有令人满意的重叠。基因型、年份和基因型×年份交互作用对所调查的蓝莓栽培品种的体外花粉表现有影响。授粉变异影响花粉在体内的表现:在所有测试的栽培品种中,开放授粉变异是最有利的,其次是异花授粉变异,但用作授粉器的栽培品种 "Nui "除外,它的结果比自花授粉变异差。此外,授粉栽培品种对授粉器的花粉性能也有影响,而开花期气温的影响只能从每种雌雄组合的反应来考虑。

期刊介绍: Erwerbs-Obstbau ist als internationales Fachorgan die führende Zeitschrift für Wissenschaftler, Berater und Praktiker im Erwerbsobstbau. Neben den wirtschaftlich führenden Obstarten widmet sich die Zeitschrift auch den Wildobstarten bzw. neuen Obstarten und deren zukünftige Bedeutung für die Ernährung des Menschen. Originalarbeiten mit zahlreichen Abbildungen, Übersichten und Tabellen stellen anwendungsbezogen den neuesten Kenntnisstand dar und schlagen eine Brücke zwischen Wissenschaft und Praxis. Die nach einem Begutachtungsprozeß zur Publikation angenommenen Originalarbeiten erscheinen in deutscher und englischer Sprache mit deutschem und englischem Titel. Review-Artikel, Buchbesprechungen und aktuelle Fachinformationen runden das Angebot ab.
