Abstract

Experiment was carried out to investigate relationships between water loss and some root parameters of corn (Zea mays L.) grown in different growing media under greenhouse conditions. Four different mixtures including at different ratios soil, perlite and peat were used. Water losses from the pots were measured during growing period. After harvesting the plants, root weight, root lenght, root diameter and root area were determined. Water loss was decreased with adding of the perlite and peat to the soil, furthermore, root weight and root lenght were decreased. A positive correlation between water loss and root weight was found at significant level (P<0.01).

Farklı Yetiştirme Ortamlarında Yetiştirilen Mısır Bitkisinin (Zea mays L.) Su Kaybı ile Kök Parametreleri Arasındaki İlişkiler

Abstract

Araştırma, su kaybının farklı yetiştirme ortamlarında ve sera koşullarında mısır bitkisinin (Zea mays L.) bazı kök parametreleri ile ilişkisini ortaya koymak için yapılmıştır. Araştırımada toprak, perlit ve peat içeren dört farklı karışım kullanılmıştır. Bitkilerin gelişimleri süresince su kayıpları ölçülmüştür. Deneme sonunda, bitki kökleri ayrılarak yıkandıktan sonra kök ağırlığı, kök uzunluğu, kök çapı ve kök alanı gibi kök parametreleri belirlenmiştir. Perlit ve peat ilavesi bitkinin su kaybını, kök uzunluğu ve kök ağırlığını azaltımıştır. Bitkirnin su kaybı ile kök ağırlığı arasında (r=0.846) % 1 düzeyinde önemli pozitif bir ilişki bulunmuştur.
