The responses of tomato cultivars grown hydroponically to low and high zinc supply in nutrient solution

Düşük ve yüksek dozdaki çinkonun, bitki gelişmesi, klorofil içeriği ve bazı makro ve mikro besin elementlerine olan etkisi incelenmek amacıyla, Blizzard ve Liberto domates çeşitleri kontrollü ısıtmalı odalarda yetiştirilmiştir. Çinko konsantrasyonları 0.01, 0.5 ve 5 mg/1 dir. Bitki gelişmesi ve klorofil üretimi açısından en iyi sonuç 0.5 mg/1 Zn uygulanmasından alınmıştır. 0.01 mg/1 Zn' te gelişen bitkiler toksik seviyede P bulunmuştur ve 5 mg/1 Zn uygulamasında ise Fe noksanlığı görülmüştür. Çeşitler arasında, düşük ve yüksek dozdaki çinkoya karşı farklılık bulunmuştur. Çeşitler arasındaki farLlıkla, bitkideki besin elementleri arasında tutarlı bir bağlantı yoktur.

Su kültüründe yetişen domates çeşitlerinin besin çözeltisindeki düşük ve yüksek dozdaki çinkoya yanıtı

Two tomato cvs, Blizzard and Lfberto, were grown in Controlled Temperature (C.T.) room in order to investigate the effects of both low and high zinc supplies on plant growth, the chlorophyll content and some macro and micro elements in plant. Concentrations of Zn were 0.01, 0.5 and 5 mg/1. In terms of plant growth and chlorophyll content, the best results were obtained from 0.5 mg/1 Zn treatment. The plants grown at 0.01 mg/1 produced P toxicity and those at 5 mg/1 showed Fe deficiency. There were differences in responses of cultivars to low and high zinc supplies. However, there seemed to be no consistent link between cultivars and nutrient concentration within the plant.
