Determination of fruit growth and fruit peel and aril colors in different pomegranate genotypes

Abstract

This study examines the growth of "Kışnarı" type with "Hicaznar" and "Kirli Hanım" pomegranate varieties in fruit length and width as well as the fruit peel and aril colors. It was found that the relationship between these type and varieties in terms of growth in fruit length and width were positive and significant and that the "Hicaznar" variety grew more robustly than the other variety and type. In addition, it was determined that width and length of the varieties and types of the fruit increased in direct proportion from the full flowering stage to the harvest period; and the fruit width growth was higher than the fruit height development. The peel L* value was determined in the range between 47.15 and 94.88 and varies by year, variety and type. The Kışnarı variety had the highest a* value (45.00) in terms of peel color while the highest b* value (41.88) was registered in the Kirli Hanım variety. The fruit peel chroma (C*) values varied between 36.99 and 63.51. It was found that the peel Hue (H ⁰ ) values of the Kirli Hanım (44.88) and Kışnarı (41.59) varieties were significantly higher than those of the Hicaznar (35.14) variety. According to aril L* values, the highest brightness was ascribed to the Kirli Hanım (73.68) while the lowest to the Hicaznar (39.80). According to a two-year average, the a* values of the aril color of the type and variety varied between 39.73 and 47.66. The aril of Hicaznar (18.25) variety had the lowest b* value aril while the Kirli Hanım (22.02) had the highest. The aril color C* values of the type and varieties varied between 43.73 and 53.99. The two-year average aril color H ⁰ value of the type and varieties varied between 24.48 (Kışnarı) and 25.95 (Kirli Hanım).
