The effects of different doses of boron on the growth parameters of some maize genotypes

Abstract

Maize is one of the important cereals in Turkey. High boron concentration effects to lose yield of maize plants. This study was conducted to determine effects of different doses of boron on growth parameters of maize genotypes in Central Anatolian Region between 2013 and 2015. OSSK 602 and DKC 5783 were used as materials. Field trials were carried out split plot design with four replications. Plant height, root length, leaf area, the number of leaves per plant, leaf fresh and dry weight, stem fresh and dry weight, root fresh and dry weight, chlorophyll A, chlorophyll B, total chlorophyll, total keratenoid, prolin, net photosynthesis, transpiration rate, water use efficiency and stoma number were investigated. As results, as boron doses increases, plant character decreased. However, level of prolin increased according to boron doses. Boron toxicity affected negatively on some phonologic, morphologic and physiological characters. © by PSP.
