Özet
Bu arastırmanın amacı sera tipi domatesin genç ve yaslı yapraklarında doğrusal ölçümlerle basit bir yaprak alanı tahmin modeli olusturmaktır. Bitki gelisiminin baslangıç asamasından baslayarak olgun safhaya kadar yaprak alanı tahmin modeli olusturmak ve doğrusal ölçümler yapmak amacıyla toplam 150 yaprak toplandı. Bu amaçla, ilk olarak domates yaprağı ana bilesenlerinin ortalama yaprakçık uzunluğu (OYU) ve yaprak ana bilesenlerinin ucundaki en uzun üç yaprakçığın yaprakçık uzunluğu (YYU) arasındaki iliski (OYU(cm) -0.361,02*YYU -0,02*YYU 2, r20.98, Esitlik 1) belirlendi. ?kinci olarak, çoklu regresyon analizi kullanılarak ortalama yaprakçık uzunluğu (OYU), ana yaprağın uç kısmındaki en uzun üç yaprakçığın uzunluğu (YYU), uç kısımdaki en uzun üç yaprakçığın genisliğine (YYG) karsılık gelen gerçek yaprak alanı dijital planimetre PLACOM ile belirlenerek bir esitlik elde edildi. Yaprak alanı tahmin modeli, LA(cm2)31,6-18.41*OYU 2.40* OYU 20.45*YYU2* YYG, r20.99 (Esitlik 2) olarak bulunmustur. Bağımsız değiskenlerin tüm alt verilerinin standart hataları p0.001 düzeyinde önemli bulunmustur. Son olarak, esitlik 1 ile esitlik 2 birlestirildiğinde nihai yaprak alanı tahmini için LA31.6-18.41*(-0.361.02*YYU-0.02*YYU2)2.40*(-0.361.02*YYU-0.02YYU2)20.45*YYU2*YYG (Esitlik 3) esitliği elde edilmistir.
The aim of this study was to produce a simple leaf area estimation model by linear measurements for young and old leaves of greenhouse type tomato. Starting from early plant growth period to mature plant stage, a total of 150 leaves were collected to carry out linear measurements and produce a leaf area estimation model for tomato. Therefore, firstly a relationship between mean leaflet length (MLL) of a main compound tomato leaf and the length of the longest leaflet (LLL) of the top three leaflets of the main compound leaf (MLL(cm)-0.361,02*LLL&#8211;0,02*LLL2, r20.98, Equation 1). Secondly, an equation was obtained by plotting actual leaf area measured by PLACOM Digital Planimeter against mean leaflet length (MLL), longest leaflet length of the top three leaflets of the main leaf (LLL) and longest leaflet width (LLW) of the top three leaflets by using multi-regression analysis. The leaf area estimation model was found as LA (cm2) 31,6&#8211; 18.41*MLL2.40*MLL20.45*LLL2*LLW, r20.99 (Equation 2). Standard errors of all subsets of the independent variables were found to be significant at p<0.001). Lastly, Equation 1 was combined with Equation 2 and final equation for leaf area estimation was obtained to be LA31.6&#8211;18.41*(-0.361.02*LLL&#8211;0.02*LLL2)2.40*(-0.361.02*LLL&#8211;0.02*LLL2) 2 0.45*LLL2*LLW (Equation 3)
