Bu çatışmada, "Robinson" mandarin çeşidinin kendilenmesi ve değişik çeşitlerle yabancı tozlanması sonucu meyve tutma oranlarının ve bazı meyve kalite özelliklerinin hangi yönde etkilendiği araştırılmıştır. Tozlayıcı olarak "Robinson", "Minneola", "Klemantin", "Fremont", "Orlando", "Kinnow" ve "Nova" çeşitleri kullanılmıştır. Ayrıca, söz konusu tozlayıcı çeşitlere ait çiçek tozlarının çimlenme ve canlılık testleri yapılmış, çiçek başına ortalama çiçek tozu üretim miktarları belirlenmiştir. "Kinnow" ile yabancı tozlamada %27-60 gibi oldukça yüksek bir meyve tutma oranına ulaşırken, "Orlando", "Klemantin", "Robinson", "Nova", ve "Fremont" ile tozlamada bu değer %2.75-4.18 arasında gerçekleşmiştir. Denemeler sonucunda en iri meyvelerin "Minneola", en küçük meyvelerin ise "Kinnow" ile tozlanan çiçeklerden elde edildiği belirlenmiştir. Öteki meyve kalite kriterleri yönünden, kombinasyonlara göre değişmek üzere, farklı sonuçlar elde edilmiştir.

Investigations into selfing and cross-pollination in relation to fruit set and fruit quality in the mandarin variety "Robinson"

Öz

This study investigated the effects of selfing and cross-pollination on fruit set and quality in the mandarin orange "Robinson." "Robinson," "Minneola," "Clementine," "Fremont," "Orlando," "Kinnow," and "Nova" served as pollen donor varieties. Furthermore, the viability and germination capacity, as well as pollen production per flower, of the pollen donor varieties were determined using in vitro tests. The highest fruit set (27.60%) was achieved in the "Kinnow" pollinated varieties, although the "Orlando," "Clementine," "Robinson," "Nova," and Fremont varieties achieved between 2.75 and 4.38% self-pollination. The results of the study showed that fruit set was positively influenced by cross-pollination with "Minneola," but negatively influenced by "Kinnow." The remaining fruit quality traits varied depending on the combinations.
