Determination of some plants properties of local melon genotypes growing in upper Coruh Valley

Abstract

This study was carried out to determine some quality parameters, yield and yield components of local melon grown in Upper Coruh Valley. Also, the study was held at field one of Ataturk University, Ispir Hamza Polat Vocational School. For that purpose, eighty six melon genotypes having different characteristic were determined in the region on 2006. Selected genotypes and 3 standard melon varieties (Ananas, Galia, Falez) being control group was grown in field condition on 2007. in the research, some development properties and yield of fruit, plant and seed was evaluated. Forty one parameters including 3 of seedling, 4 of plant, 9 of leaf, 22 of fruit, 3 of seed for melons was investigated such as fruit weight, fruit diameter, length of fruit, fruit cavity, fruit cavity width, fruit cavity length, fruit flesh thickness, skin thickness, skin color, fruit flesh color. Such as fruit weight, fruit diameter, length of fruit, fruit cavity, fruit cavity width, fruit cavity length, fruit flesh thickness, skin thickness, skin color, fruit flesh color. Cotyledon leaf width was 14.26-29.04 mm; cotyledone leaf length was 16,86-45,33 mm and hypocotyl length was 10,53-36,12 mm. in the genotypes examined, branch length changed from 117,17 to 287,33 cm, number of branches varied from 9,50 to 40,50, stem diameter varied from 11,76 to 24,19 mm. pH was 5,50-7,20, acidity 0.06-0.15 g /100ml; ascorbic acid values were 2.1-39.3 mg / 100ml. the results obtained for TTS, pH and acidity were similar to both standard varieties and previous studies. Variation in ascorbic acid was found to be wider in genotypes examined.
