Correction of zinc definciency by follar application in tomato plants grown hydroponically

Moneymaker domates çeşidi, çinko noksanlığım gidermek amacıyla yapraktan verilecek en uygun çinko dozunu araşurmak için su kültüründe ve kontrollü ısıtmalı odalarda yetiştirilmiştir. Çinko besin çözeltisine 0.01 veya 0.1 mg/1 olarak katılmış ve yapraktan ise 0.01 veya 0.1% çinko sülfat olarak püskürtülmüştür. 0.01mg/l Zn'de yetişen bitkiler, 0.1 mg/1 yetişen bitkilerden daha az kuru madde ve klorofil üretmişlerdir. 0.01% çinko sülfat püskürtülmesi çinko noksanlığını gidermiş ve aynı zamanda kuru madde ve klorofili de artırmıştır. Ancak, 0.1% çinko sülfat'ın yapraktan püskürtülmesi, 0.1 mg/1 Zn yetişen bitkilerde olumsuz etkide bulunmuştur. P konsantrasyonu, 0.01mg/1 Zn yetişen bitkilerde toksik seviyede bulunmuştur, ancak yaprak gübrelemesiyle bu toksik etki ortadan kalkmıştır, yapraktaki Fe konsantrasyonu, 0.01 mg/1 Zn ile artmıştır ve çinkonun yapraktan uygulanmasıyla azalmıştır.

Su kültüründe yetişen domates bitkisinde yaprak gübrelemesiyle çinko noksanlığının giderilmesi

Tomato cultivar, Moneymaker, was grown hydroponically in Controlled Temperature (C.T.) room in order to investigate optimum dose which can correct zinc deficiency as foliar application without adverse effects. Zinc was added nutrient solution at the concentration of 0.01 or 0.1 mg/1 and applied as foliar application at 0.01% or 0.1% zinc sulphate. Plants grown at 0.01 mg/1 zinc produced less dry matter and chlorophyll than those at 0.1 mg/1. Foliar application of zinc sulphate at 0.01% correct zinc deficiency and increased dry matter and chlorophyll concentration. However, 0.1% zinc sulphate as foliar application caused to detrimental effect to the plants grown at 0.1 mg/ zinc in nutrient solution. Concentration of P was toxic level in the leaves of plant at 0.01 mg/1 Zn supply and foliar application correct this toxicity. Fe concentration in the leaves was slightly increased by 0.01mg/l Zn and suppressed by foliar application of zinc.
