Bu çalısma bazı Japon erigi çesitlerinin ( Obilnaja, Black Diamond, Fortune, Autumn Giant ve Queen Rose)
Aydın ekolojisindeki gelisme durumlarını saptamak amacıyla 2003-2005 yıllarında Adnan Menderes
Üniversitesi Ziraat Fakültesi Bahçe Bitkileri Bölümünde yürütülmüstür. Obilnaja çesidi ( 2004 yılında 15
Haziran, 2005 yılında 23 Haziran ) en erken hasat edilen çesit olmustur. En geç hasat edilen çesit 26 Temmuz
tarihi itibariyle Fortune çesididir. Ilk deneme yılındaki verim 7,085 kg/agaç (Black Diamond) ile 0,680kg/agaç
(Queen Rose ) arasında olurken, ikinci yıldaki verim 22,216 kg/agaç (Black Diamond) ile 12,612 kg/agaç (Queen
Rose ) arasında saptanmıstır. Meyvesi en iri çesit 2004 yılında 49,80 gr ile Queen Rose olurken,meyvesi en küçük
çesit 38,56 gr ile Obilnaja olmustur.2004 yılında en yüksek kuru madde miktarı % 17,5 ile Black Diamond
çesidinde, denemenin ikinci yılında ise % 18,2 ile Fortune çesidinde tesbit edilmistir. Denemeye alınan
çesitlerden gövde kesit alanına düsen ortalama verimler sırasıyla Black Diamond, (0,9964 kg/cm ), Obilnaja
(0,365 kg/cm ) Queen Rose (0,356 kg/cm )çesitlerinde saptanmıstır.
In both years, Obilnaja was harvested first ( 15 June in 2004, 23 June in 2005). Black Diamond and Queen Rose
reached fruit maturity on 12 July in 2004. On the other hand, in 2005 Black Diamond reached fruit maturity one
week earlier than 2004. However, Obilnaja was harvested on 12 July 2005, similar to 2004. The lastest fruit
maturity was observed in Fortune on July.. Based on pomological analyses, in first year while yield was second
year, yield was varied from 22,16 kg/tree to 12,612 kg/tree in the second year. In 2004, Queen Rose had the
biggest fruit with 49,80 g., but Obilnaja had the smallest fruit with 38,36 g. In 2005, similar to the first
experimental year, Queen Rose had the biggest fruit, with 37,02 g., while Obilnaja had the smallest fruit with
13,76 g. In the first year of the experiment fruit flesh firmness changed between 4,410 and 3,843 kg/cm for Black
Diamond and Queen Rose respectively. In the second year, It was found that fruit flesh firmness was 2,980 kg/cm
for Black Diamond.White Black Diamond cultivar had the highest dry matter, %17,5, in the first year, Fortune
cultivar had the highest dry matter, %18,2, in the second year. Obilnaja cultivar was the first rank with regard to
acid (2,85-2,81 ) based on pH value. The average mean of cultivar for per yield was 0,9964 kg/cm for Black
Diamond which was followed by Obilnaja with 0,365 kg/cm and Queen Rose with 0,356 kg/cm .
