Abstract
Bu çalışmanın amacı, Samsun ekolojik koşullarında sonbahar döneminde yetiştirilen alabaş (Brassica oleracea var. gongylodes L.) çeşitlerinin farklı tohum ekim zamanlarına bağlı olarak büyümesindeki değişimlerin kantitatif olarak incelenmesidir. Bu amaçla, 2005–2006 yıllarında arasında iki yıl süreyle sonbahar döneminde, 15’er gün aralıklarla beş farklı tohum ekim zamanı (15 Temmuz, 1 Ağustos, 15 Ağustos, 1 Eylül, 15 Eylül) ve iki alabaş çeşidi (Korist F1, Kolibri F1) denenmiştir. Bitkilerde dikimden itibaren 20 ve 40 gün sonra olmak üzere kantitatif analizler yapılmıştır. Bu analizlerde, oransal yaprak ağırlığı (OYA), oransal gövde ağırlığı (OGA), oransal kök ağırlığı (OKA), yaprak alanı (YA), oransal yaprak alanı (YAO), özgül yaprak alanı (ÖYA), yaprak kalınlığı (YK), net asimilasyon oranı (NAO) ve nispi büyüme hızı (NBH) parametreleri incelenmiştir. Araştırmada, çeşit ve ekim dönemlerine bağlı olarak kantitatif analizlerde sırasıyla OKA 0.04-0.29 g/g, OGA 0.14-0.54 g/g, OYA 0.39-0.78 g/g, YA 94.075-723.2 cm2, YAO 23.1-324.2 cm2/g, ÖYA 47.6-530.6 cm2/g, YK 0.002-0.021, NAO 0.0002-0.0339 g/cm2/gün ve NBH’nın ise 0.04-3.08 g/g/gün arasında değiştiği saptanmıştır. Bitki büyüme parametreleri arasında istatistiksel olarak önemli seviyede pozitif ve negatif korelasyonların olduğu da bulunmuştur. Tohum ekim zamanları arasında en yüksek NAO ve NBH’nın 15 Temmuz döneminde daha yüksek olduğu belirlenmiştir. QUANTITATIVE EFFECTS OF DIFFERENT SOWING TIMES ON THE GROWTH OF KOHLRABI (Brassica oleracea var. gongylodes) GROWN IN AUTUMN PERIOD IN SAMSUN ECOLOGICAL CONDITIONSthis study was carried out to investigate the effect of different seed sowing dates on the growth of kohlrabi cultivars grown under Samsun ecological conditions during the autumn growing periods in 2005 and 2006. Five sowing times (15th July, 1st August, 15th August, 1st September, 15th September) and two cultivars (Korist F1, Kolibri F1,) were tried for the autumn season. Quantitative analyses of the plants were done at 20 and 40 days after planting. The plant growth parameters investigated were; leaf weight ratio (LWR), stem weight ratio (SWR), root weight ratio (RWR), leaf area (LA), leaf area ratio (LAR), specific leaf area (SLA), leaf thickness (LT), net assimilation rate (NAR) and relative growth rate (RGR). RWR, SWR, LWR, LA, LAR, SLA, LT, NAR and RGR ranged between 0.04-0.29 g/g, 0.14-0.54 g/g, 0.39-0.78 g/g, 94.075-723.2 cm2, 23.1-324.2 cm2/g, 47.6-530.6 cm2/g, 0.002-0.021, 0.0002-0.0339 g/cm2/day, 0.04-3.08 g/g/day for all quantitative analyses, respectively. Significant positive and negative correlations were also found among the plant growth parameters. The highest NAR and RGR values were determined in the plants which were sown on July 15 for autumn growing periods.
