| Abstract:
This study was carried out to determine the causal relations between fruit weight and certain fruit characteristics by using the path analysis. 162 native apricot trees were used in this study. The fruit weight (FW) was considered as a dependent variable and the effects of fruit length (FL), fruit suture (FS), fruit cheek (FC), dry matter (DM) and seed weight (SW) on changes in the dependent variable were researched. The stepwise analysis was carried out for this purpose. According to the results the best model was FW = -63.66 + 0.81 FL + 0.69FS + 0.93FC + 0.18DM. The independent factors in the model explained 0.85 percent of variation of FW. The SW had no effect on the explained variation in FW (P>0.05). The path analysis was used to determine the causal relationship between FW and other variables. The highest correlation coefficient observed between FC and FW was 0.88, and the highest path coefficient observed between FW and FS was 0.45. | |
