Salicylic acid (SA) plays an important role in plant response to abiotic stresses. This study investigated the potential role of SA in alleviating the adverse effects of chilling stress on photosynthesis and growth in watermelon (Citrullus lanatus). Chilling stress induced the simultaneous accumulation of free and conjugated SA in watermelon plants, and the chilling-induced SA production was at...

Low temperature is a major factor limiting the productivity and geographical distribution of many plant species. In this study, we investigated the effect of chilling stress (10 C) on seedling growth in two sweet sorghum (Sorghum bicolor (L.) Moench) inbred lines (M-81E and Roma). Results showed that the chilling resistance of M-81E was higher than that of Roma. The Fv/Fm in leaves of M-81E dec...

The regulatory mechanisms underlying bud breaking (scale leaf elongation) and flowering in the lateral flower buds of Japanese pear (Pyrus pyrifolia Nakai 'Kosui') are unknown. To more fully characterize these processes, we treated pear trees with different amounts of chilling initiated at different times. Chilling for ∼900 h at 6 °C always induced bud breaking (scale elongation in ≥70% lateral...

This study was carried out in the biotechnology laboratory of Agricultural Faculty of Ondokuz May s University. The objective of this study was to establish the effects of chilling period and chilling temperature on germination in linseed (Linum usitatissimum L.). Seeds were subjected to six different heat temperatures (0, 2, 4, 6, 8 and 10 C) for 24, 48, 72, 96, and 120 hours. Germination test...

Understanding germination requirements of native species is an important component of restoration in south Puget Lowland prairies (Washington, USA). We conducted an experiment to determine the effects of pre-germination treatment and germination temperature conditions on the proportional germination of three species of Lupinus. For one species, Lupinus lepidus, germination was highest following...

Salicylic acid (SA) is a naturally produced compound and has been implicated to play important roles in defense of plants against diverse biotic and abiotic stresses. To understand how SA functions in the tolerance of cucumber (Cucumis sativus) to chilling stress, endogenous SA levels in two different cultivars with opposite chilling responsiveness were quantified. Membrane integrity, including...
