Study on Cone Formation Stage of Caucasian Fir (Abies nordmanniana ssp. nordmanniana)

Determination of the good seed year is important to obtain high quality and quantity seeds from stands. Also, pollination and fertilization need to be done without problems. Tree quality, health and good seed bearing capacity is related to climatic factors during flowering and seeding stage and related to site conditions. Healthy, high quality and enough number of seeds are required in order to have a successful natural regeneration. Observing the morphological characteristics of trees in the stand or as single trees is the fastest, easiest and cheapest way to characterize their health status. In this study, a tree species, Caucasian fir, from the Karadeniz Technical University campus was observed. Phenological changes of the male and female flowers will be observed periodically and photos of these changes will be provided. During the early months observations will be weekly but on later periods observations will be bi-weekly. Caucasian fir’s pollination, fertilization, cone formation, cone growth and seed fall will be determined based on observations and the study results
