Tohum Ağırlığının Buğday ve Fasulyenin Gelişimi ve Mineral Beslenmesine Etkileri

Bu çalışmada, buğday ve fasulye bitkilerinin gelişimi, mineral beslenmesi ve besin elementi alımları üzerine farklı tohum ağırlıklarının etkilerini incelemek amaçlanmıştır. Bu nedenle ağırlıkları 3.35, 4.05 ve 4.98 g/100 tohum olan buğday tohumlarıyla, ağrılıkları 30.02, 45.18, 54.01 ve 58.6 g/ 100 tohum olan fasulye tohumları iki kg toprak alan saksılara ekilerek 2 ay süreyle sera koşullarında gelişmeye bırakılmışlardır. Deneme süresi sonunda bitkiler hasat edilmiş ve besin maddesi tayinleri için analiz edilmişlerdir. Analiz sonuçlarına göre, bitki kuru ağırlıklarının her iki bitkide de tohum ağırlığıyla arttığı görülmüştür. Buğdayda Fe, Zn ve Mn konsantrasyonlarıyla topraktan alınan K, Ca, Mg, Fe, Zn ve Mn miktarları tohum ağırlıklarının artmasıyla artmıştır. Benzer şekilde fasulye bitkisinin N, Ca ve Mg konsantrasyonuyla topraktan kaldırılan K, Ca, Mg, Fe, Cu, Zn ve Mn miktarları artan tohum ağırlıklarıyla artmıştır. Her iki bitki için de, genelde tohum ağırlıklarıyla tohumun besin elementi içerikleri arasında bir ilişki görülmezken, tohum ağırlıklarıyla bitki kuru ağırlığı, besin elementi içeriği ve topraktan alınan besin elementi miktarları arasında bazı korelasyonlar belirlenmiştir.

Effects of Seed Weights on Plant Growth and Mineral Nutrition of Wheat and Bean Plants

This study was aimed to investigate the effects of different seed weights on plant growth, mineral nutrition and nutrient uptake of wheat and been plants. Also relations among seed weights and examined parameters were examined. For this purposes, 3 groups of wheat grains having 3.35, 4.05 and 4.98 g 100 seeds-1 and 4 groups of been grains having 30.02, 45.18, 54.01 and 58.6 g 100 seeds-1 were selected. Experiment was set up under greenhouse condition and left for growing during 2 months. After the experimental period, plants were harvested and analyzed for mineral analysis. According to the results it was seen that dry weights of both plants increased with the seed weights. For wheat plants, increasing of seed weights led to increase of plant Fe, Zn and Mn concentrations. Also K, Ca, Mg, Fe, Zn and Mn uptake of plant from the soil increased with increase of 100 seed weights. Similarly, N, Ca, Mg and concentrations of bean and nutrient uptake (K, Ca, Mg, Fe, Cu, Zn and Mn) from the pot increased with the seeds weights. For both plants, while there were not any correlations among seeds weights and seed nutrient concentrations generally, there were some significant correlations among the seeds weights and dry weights, leaf nutrient concentrations and nutrient uptake.
