Farklı yulaf (Avena sativa L.) genotiplerinin destek sulamalı ve sulamasız koşullarda bazı kalite özelliklerinin değerlendirilmesi

Yulaf nişasta, protein, diyet lif, yağ asitleri ve β-glukan gibi besin maddeleri açısından zengin olduğundan hem insanlar hem de hayvanlar için önemli bir temel besin kaynağı olarak kullanılmaktadır. Bu çalışma, 22 yulaf genotipinin bazı kalite özelliklerinin, yağışa dayalı ve destek sulamalı koşullarda incelenmesi amacıyla 2016-2017 yetiştirme sezonunda Yozgat’ın Yerköy ilçesinde yürütülmüştür. Denemeler üç tekrarlamalı olarak tesadüf blokları deneme desenine göre kurulmuştur. Araştırmada genotiplerin nişasta, protein, β-glukan, yağ ve yağ asitleri oranları ile asit deterjanda çözünmeyen lif (ADF) ve nötr deterjanda çözünmeyen lif (NDF) değerleri incelenmiştir. Yağışa dayalı koşullarda genotiplerin nişasta oranı %37.1-47.6, protein oranı % 12.7-15.2, β-glukan oranı % 3.53-4.58, yağ içeriğinin %4.64-7.89, linoleik asit içeriğinin % 28.8-37.2, oleik asit içeriğinin % 37.1-47.1, palmitik asit içeriğinin % 21.7-23.5, stearik asit içeriğinin % 1.74-2.05, ADF değerinin %11.9-16.9 ve NDF değerinin %30.1-37.1 arasında değiştiği belirlenmiştir. Destek sulamalı koşullarda ise genotiplerin nişasta oranı % 39.4-49.0, protein oranı %12.3-14.6, β-glukan oranı % 3.44-4.06, yağ içeriği % 4.87-8.27, linoleik asit içeriği % 29.0-37.1, oleik asit içeriği % 36.3-46.5, palmitik asit içeriği % 22.7-24.8, stearik asit içeriği % 1.86-2.05, ADF değeri % 12.0-16.3 ve NDF değeri % 30.3-37.5 arasında değişmiştir. Yağışa dayalı koşullarda G3, G6, G8, G9 ve G15 numaralı genotipler, destek sulamalı koşullarda G3, G8, G9, G11, G13 ve G15 numaralı genotipler nişasta, protein ve β-glukan içeriği bakımından ortalamanın üstünde değerlere sahip olurken, ADF ve NDF içeriği bakımından ortalamanın altında değerlere sahip olmuşlardır.

Evaluation of Some Quality Traits of Different Oat (Avena sativa L.) Genotypes under Supplemented Irrigation and Without Irrigation

Oat is use as an important source of essential nutrients for both humans and animals because of it is rich in nutrition composition like starch, protein, dietary fiber, fatty acid and β-glucan etc. This study was conducted to determine some quality traits of 22 oat genotypes in Turkey in rainfall and supplemented irrigation conditions during 2016-2017 growing season at Yerköy/Yozgat. Experiments were carried out in randomized complete block design with three replications. In the trials, starch, protein, β-glucan, fat, fatty acid ratios, acid detergent fiber (ADF) and neutral detergent fiber (NDF) values were investigated. In experiment without irrigation, among the genotypes, starch ratio varied from 37.1 to 47.6%, protein ratio from 12.7 to 15.2%, β-glucan content from 3.53 to 4.58%, fat ratio from 4.64 to 7.89%, linoleic acid content from 28.8 to 37.2%, olaic acid content from 37.1 to 47.1%, palmitic acid content from 21.7 to 23.5%, stearic acid content from 1.74 to 2.05%, ADF content from 11.9 to 16.9% and NDF content from 30.1 to 37.1%,. in the trial irrigated with supplemented irrigation, among the genotypes, starch ratio varied from 39.4 to 49.0%, protein ratio 12.3 to 14.6%, β-glucan content from 3.44 to 4.06%, fat ratio from 4.87 to 8.27%, linoleic acid content from 29.0 to 37.1%, oleic acid content from 36.3 to 46.5%, palmitic acid content from 22.7 to 24.8%, stearic acid content from 1.86 to 2.05%, ADF content from 12.0 to 16.3% and NDF content from 30.3 to 37.5%,. Genotypes G3, G6, G8, G9 and G15 under rainfall conditions, genotypes G3, G8, G9, G11, G13 and G15 under supplemented irrigation had higher than average values in terms of starch, protein and β-glucan values while they had below average values in terms of ADF and NDF.
