Abstract
Bu projeyle Türkiye'de yıl boyunca krizantem üretimi başlatıldı. Krizantem, 14,5 saatlik kritik gün uzunluğu gerektiren bir kısa gün bitkisidir. Türkiye, 36°-42°K enlemleri arasındadır. 15 Ağustos ile 1 Mayıs arasında gün uzunlukları 14,5 saatten kısadır. Bu nedenle, bu dönemde erken tomurcuklanmayı önlemek için 7-10 derecelik ışık yoğunlukları kullanmak gerekir. 1. Yöntem ile 15 Ağustos arasında gün uzunluğu 14,5 saatten uzun olduğundan, tomurcuk oluşumunun başlaması için gün başlangıcından itibaren 4 hafta karartma yapılması gerekir.

Abstract
All year around chrysanthemum production was initialed with this project in Turkey. Chrysanthemum is a short- day plant which requires critical day length of 14.5 hours. Turkey is between 36°-42°N. Latitudes and the day lengths is shorter than 14.5 hours between August 15 and May 1. It is, therefore, necessary to use 7-10 f/c light intensities to prevent premature budding in this stage. Between Way 1 and August 15 the day length is longer than 14.5 hours, therefore, making blackout 4 weeks from day in order to start bud initiation.
