Bu çalışmada, verimin 1/4'üne kadar meyve seyreltmesinin etkileri ve iki yıllık ağaçların verimleri arasındaki ilişkiler araştırılmıştır. Meyve seyreltmesinin, sonraki iki hasadın meyve özellikleri ve verimi üzerinde bir etkisi olmadığı bulunmuştur. Verim ile askorbik asit içeriği, verim ve meyve indeksi arasında negatif korelasyonlar, ancak verim ile meyve kabuğunun kırmızı rengi (Hunter 'a') arasında pozitif korelasyon vardır. 1973'te rastgele seçilen ve ertesi yıl verimi kısmen artan, kısmen azalan ağaçların yıllık verimleri arasında negatif korelasyon (r = -0,48) vardır. Buna karşılık, 1974'te iyi ve verimli olarak kasıtlı olarak seçilen ve verimleri azalan ağaçlarda pozitif korelasyon (r = 0,82) vardır. Verim değişimleri arasındaki korelasyon katsayıları her iki durumda da negatiftir (r = -0,82, r = -0,55).

Influence of fruit thinning by hand on fruit quality and yield of ‘Satsuma’ trees, and the relationships between the yield of two subsequent years

Öz

This study investigated the effects of fruit thinning down to 1/4 of the yield and the relationships between the yields of two years of trees. It was found that fruit thinning has no influence on the fruit characteristics and yields of two subsequent harvests. There are negative correlations between yield and ascorbic acid content, yield and fruit index, but a positive correlation between yield and the red coloration of the fruit skin (Hunter 'a'). There is a negative correlation (r = -0.48) between annual yields of trees randomly selected in 1973, whose yields partly increased and partly decreased in the following year. In contrast, there is a positive correlation (r = 0.82) for trees deliberately selected in 1974 as good and productive, whose yields decreased. The correlation coefficients between the yield changes are negative in both cases (r = -0.82, r = -0.55).
