Effect of acetaldehyde, arsenite, ethanol, and heat shock on protein synthesis and chilling sensitivity of cucumber radicles.
Exposure to a chilling temperature of 2.5 degrees C for 96 h inhibited the subsequent growth of cucumber seedling radicles at 25 degrees C by 92%. Exposing seedling with 5 +/- 1 mm long radicles to acetaldehyde vapour (275 micro l l(-1)) or to an aqueous ethanol solution (0.6 M) for 2 h, or to 45 degrees C for 10 min before chilling, increased chilling tolerance so that the chilling treatment r...
متن کاملHeat shocks increase the chilling tolerance of rice (Oryza sativa) seedling radicles.
The growth of rice (Oryza sativa L., cv. M202) seedling radicles, initially 10 +/- 1 mm long, was linear for the 96 h it took them to grow to 150 mm at 25 degrees C. Exposure to 5 degrees C for 24 h reduced the rate of growth by about 50%, and longer exposures caused a progressive reduction in growth. Initial radicle length significantly affected chilling sensitivity: with 2 days at 5 degrees C...
متن کاملInvolvement of polyamines in the chilling tolerance of cucumber cultivars.
The possible involvement of polyamines (PAs) in the chilling tolerance of cucumber (Cucumis sativus L. cv Jinchun No. 3 and cv Suyo) was investigated. Plants with the first expanded leaves were exposed to 3 degrees C or 15 degrees C in the dark for 24 h (chilling), and then transferred to 28 degrees C/22 degrees C under a 12-h photoperiod for another 24 h (rewarming). Chilling-tolerant cv Jinch...
متن کاملAlleviating effect of exogenous nitric oxide in cucumber seedling against chilling stress
Nitric oxide (NO) is a bioactive and a multifunctional gaseous molecule signal playing a central role and mediating variety of physiological processes in plants. In this study, the protective effect against chilling stress of exogenously applied sodium nitroprusside (SNP, a NO donor) in Cucumis sativus L. cv ZND407 and cv ZND461 was investigated. The SNP was sprayed over cucumber seedlings usin...
متن کاملStimulation of Solute Loss from Radicles of Gossypium hirsutum L. by Chilling, Anaerobiosis, and Low pH.
The loss of organic substances from cotton (Gossypium hirsutum L.) radicles is enhanced by chilling, low pH, or anaerobic conditions. Solute loss returns to a low level when the stimulus is removed, indicating no permanent injury to membranes. Loss of solute induced by chilling or anaerobiosis is reversed or prevented by calcium or magnesium. These cations did not reduce the solute loss resulti...
