Çalışmanın amacı: Bu çalışma, nemli bir orman plantasyonunda G. kola'nın mevsimsel iklim değişimini ve çiçeklenme yoğunluğunu değerlendirmek amacıyla tasarlanmıştır.
Çalışma alanı: Çalışma, Nijerya Ormancılık Araştırma Enstitüsü'nün Onne, Rivers Eyaleti, Nijerya'daki Bataklık Ormanı Araştırma İstasyonu'nda bulunan Garcinia kola'nın tek türlü plantasyonunda gerçekleştirilmiştir. Plantasyon, 5x5 m aralıklarla dikilmiş 103 ağaçtan oluşmaktadır.
Materyal ve yöntem: İklim verileri meteoblue.com'dan elde edilmiştir. Çiçeklenme yoğunluğu, her bir ağaçtaki toplam çiçek üretiminin tahmin edilmesiyle belirlenmiştir: Her bir infloresans başına çiçek tomurcuğu sayısı görsel olarak sayılmış ve ardından her bir dal başına infloresans sayısı, dal başına dal sayısı ve ağaç başına dal sayısı ekstrapole edilerek her bir ağaç için ortalama çiçeklenme yoğunluğu hesaplanmıştır. Toplamda 9 ağaç ve her bir ağaçtan 25 infloresans örneklenmiştir. Veriler kovaryans ve varyans analizleri kullanılarak analiz edilmiştir.
Temel sonuçlar: Yağış, rüzgar hızı ve çiçeklenme yoğunluğu mevsimler arasında önemli ölçüde (p ≤ 0.05) değişiklik göstermiştir; mevsimsel yağış değişiminin çiçeklenme yoğunluğu üzerindeki etkisi ağaç cinsiyetine göre farklılık göstermiştir.
Araştırma vurguları: Yağış, plantasyonda çiçeklenmenin belirleyici unsurudur; çiftçilere yüksek meyve ve tohum verimi elde etmek için düşük ila orta yağışlı mevsimleri hedeflemelerini öneriyoruz.

Seasonal Climatic Variation and Flowering Intensity of Garcinia kola (Heckel) in a Humid Forest Plantation

Öz

Aim of study: The study designed to assess seasonal climatic variation and flowering intensity in G. kola in a humid forest plantation.
Area of study: The study was conducted in the mono-plantation of Garcinia kola in the Swamp Forest Research station of the Forestry Research Institute of Nigeria, Onne, Rivers state, Nigeria. The plantation consists of 103 trees at 5×5m spacing.
Material and methods: Climatic data were sourced from meteoblue.com. Flowering intensity was determined by the estimation of the total flower production per tree: total number of flower buds per inflorescence was determined by visual counting and then extrapolated for the total number of inflorescences per twig, total number of twigs per branch and total number of branches per tree to determine the average flowering intensity per tree. A total of 9 trees and twenty-five inflorescences per tree, were sampled. Data was analysed using covariance and analysis of variance.
Main results: Rainfall, wind speed, and flowering intensity varied significantly (p ≤ 0.05) between seasons; seasonal rainfall variation influence on flowering intensity varied with tree gender.
Research highlights: Rainfall is the flowering cue of the plantation; we recommend that farmers target low to moderate rainfall seasons for high fruit and seed yields.
