Bazı ağır metallerin at dişi mısır (Zea mays L.)’da çimlenme ve erken fide gelişimi üzerine etkileri

Abstract

This study was carried out to determine the effects of different heavy metals and its doses on germination and early seedling stage of maize (Zea mays L.) at the Akdeniz Univesity, Agricultural Faculty, Department of Field Crops in 2017. Heavy metals such as lead (Pb), nickel (Ni), chromium (Cr), cadmium (Cd) and mercury (Hg) and its doses such as 0 (control), 100, 200, 400 and 800 mg L -1 were used as experimental factors. This research was laid out on the factorial arrangements design in randomized parcels with 4 replications. Germination percentage (%), germination index, mean germination time (day), radicle length (mm), plumula length (mm), radicle fresh weight (mg plant -1 ), plumula fresh weight (mg plant -1 ), radicle dry weight (mg plant -1 ) and plumula dry weight (mg plant -1 ) properties were investigated in germination and early seedling stage of maize. As results of this study, Toxicity effects of heavy metals used in this research were listed as mercury> cadmium> lead> chromium> nickel. Also, in 400 and 800 mg L -1 doses of mercury and cadmium heavy metals were found to be more toxic than the same doses of others. 100 and 200 mg L -1 doses of heavy metals used in this work caused the stimulant effects on germination and early seedling stage of maize.

Screening For Salt Tolerance of 12 Turkish Triticale Cultivars during Germination and Early Seedling Stage

“…Biomass weight (BW) of triticale cultivars decreased as the salt dose increased (Figure 10). It has been reported by various studies that growth was restricted and biomass weight decreased in plants under various abiotic stress conditions (Ertekin et al, 2020;Ertekin and Bilgen, 2021;Aygün et al, 2022).…”
