Özet:

 In recent years, excessive nitrogen N fertilizer application has adversely affected the ecosystem. Additionally, inefficient fertilizer use can diminish soil fertility and result in the loss of organic matter. Limiting access to N fertilizer leads to increased prices, which consequently results in reduced crop productivity. Developingbreeding nitrogen-efficient plants is another strategy to enhance N uptake and efficiency in crops. The aim of this study was to assess the genotypic differences of 27 double haploid DH melon genotypes under low nitrogen 0.3 mM conditions based on biomass parameters in hydroponic growth conditions. Significant differences were determined among the genotypes in all the parameters investigated. At low nitrogen levels, the highest stem fresh weight was recorded in genotypes C19 48.53 gplant and D10 42.57 gplant, while the highest leaf fresh weight was observed in genotypes C8 51.57 gplant and C19 51.37 gplant. In plants subjected to low N, the highest stem dry weight was found in genotypes E13 and C19, whereas the lowest was recorded in genotypesB9 and C5 with 2.10 gplant. Under low nitrogen conditions, genotypes I7 and CA7 exhibited the highest root fresh and dry weights, respectively. The average shootroot ratio of melon genotypes under low nitrogen conditions was 1.40, with the highest ratio in genotype B5 2.69 and the lowest in genotype I7 0.76. Melon genotypes had an average root length of 4000.92 cm under low nitrogen conditions, with genotype I7 having the longest root with 8194.43 cm and genotype B5 having the shortest root with 1795.34 cm. Under low nitrogen stress, genotypes displayed significant variation in plant growth. In terms of shoot fresh weight, there was a two-fold difference between susceptible and tolerant genotypes, while for root fresh weight, the difference was four-fold. This indicates that tolerance to nitrogen is attributed to changes in the root system rather than the shoot system.
