Response to gravity by Zea mays seedlings. I. Time course of the response.
Gravistimulation induces an asymmetric distribution of free indole-3-acetic acid (IAA) in the cortex-epidermis of the Zea mays L. cv 'Stowells Evergreen' mesocotyl within 15 minutes, the shortest time tested. IAA was measured by an isotope dilution method as the pentaflurobenzyl ester. The per cent IAA in the lower half of the mescotyl cortex was 56 to 57% at 15, 30, and 90 minutes after stim...
متن کاملEvaluation of oxidative stress tolerance in maize (Zea mays L.) seedlings in response to drought.
Seedlings of selected six genotypes of maize (Zea mays L.) differing in their drought sensitivity (LM5 and Parkash drought-tolerant and PMH2, JH3459, Paras and LM14 as drought-sensitive) were exposed to 72 h drought stress at two leaf stage. Alterations in their antioxidant pools combined with activities of enzymes involved in defense against oxidative stress were investigated in leaves. Activi...
متن کاملGrowth Response of Seedlings of Zea Mays (L.) to Aqueous Extract of Lycopodium Clavatum (L.)
Natural selection is a phenomenon, which allows nature to select at any point in time the structure and number of organism living in a particular habitat [1]. This competitive tendency has been shown and reported by several authors Bonner [2], Grummer et al. [3], Evenari (1961), Whittaker [4], Putman and Duke [5], and Fischer et al. [6]. Allelopathic behaviour can best be described as direct or...

متن کاملEffects of aluminum toxicity on maize (Zea mays L.) seedlings
Aluminum toxicity is one of the most deleterious factors for plant growth in acidic soils because over 50% of the world’s potentially arable lands are acidic. In recent years, considerable research has been conducted to understand the mechanisms of Al toxicity and tolerance in plants. This paper reviews the effects of different concentration of Al on plant shoot, root physiological parameters s...
