WEAVER1 has shown that autumnal application of gibberellin prolongs dormancy of Vitis vinifera shoots in the following spring. We2 recently reported that application of gibberellic acid in late summer and autumn delayed leaf-fall of several woody species; further observations on these plants this spring have shown that in many of them dormancy was prolonged. Thus this unexpected response to gibberellins may not be uncommon. 
Gibberellic acid-induced prolongation of the dormancy in tubers or rhizomes of several species of East Asian Dioscorea
TLDR
Effects of the application of gibberellic acid on sprouting of tubers or rhizomes were tested in seven species of the genus Dioscorea that are native to the temperate regions of East Asia and some responses differed between species and between sections of the species. Expand
Expansion of trait of gibberellin-induced dormancy in the Tertiary relict species of the genus Dioscorea (Dioscoreaceae)
TLDR
It is hypothesized that before disjunction in the Tertiary period GA-induced dormancy probably prevailed in rhizomes of all members of the genus Dioscorea. Expand
Gibberellin-induced dormancy in bulbils of Dioscorea
SummaryThe sprouting of bulbils of some plants in genus Dioscorea was inhibited by gibberellin (GA) treatment and was promoted by treatment with growth retardants. The results suggest that endogenousExpand
Dormancy in peach (Prunus persica L.) flower buds
TLDR
In isolated peach buds fertile verticils are not sufficiently developed during the resting time to allow sprouting, so vegetative buds were almost completely developed by midsummer/early automn and remained in a resting state until the end of winter. Expand
Effects of bud scales and gibberellins on dormancy of in vitro cultured Japanese pear leaf buds
TLDR
The delaying effect of scales on expansion of summer buds was effectively removed by application of GA 4+7 to the medium, and the presence of bud scales delayed expansion ofSummer dormant buds, while it had little effect on winter dormant buds. Expand
Dormancy in peach (Prunus persica L.) flower buds
Morphological studies were carried out with peach flower buds collected monthly in 1989 and 1990, from two months before leaf fall (7 March) until two to three weeks before bloom (7/8 August).Expand
Identification of Endogenous Gibberellins in Dormant Bulbils of Chinese Yam, Dioscorea opposita.
TLDR
Internal GAs identified by Kovats retention indices and full mass spectra from capillary gas chromatography-mass spectrometry analysis of purified extract from dormant bulbils of Dioscorea opposita Thunb suggest the occurrence of two biosynthetic pathways in D. opposita bulbils. Expand
The Physiology of Chilling Temperature Requirements for Dormancy Release and Bud-break in Temperate Fruit Trees Grown at Mild Winter Tropical Climate
It is studied that inadequate winter chilling may interfere with the normal processes of plant growth, reproductive development and subsequent yield. As much of the evidences behind these studies areExpand
Beneficial effects of cold-moist stratification on seed germination behaviors of Abies pindrow and Picea smithiana
TLDR
Overall results showed that soaking seeds in GA3, moist-chilling and temperature on seed germination of Abies pindrow and Picea smithiana produced an effective germination in both the species studied. Expand
Gibberellin-induced inhibition and promotion of sprouting in aerial tubers of Begonia evansiana Andr. in relation to photoperiodic treatment and tuber stage
Gibberellic-acid (GA3) treatment, when applied within a period ranging from the start of short-day (SD) treatment until about 10 SD, GA3 strongly inhibited formation of aerial tubers in response toExpand

Effects of Gibberellic Acid on Development of Autumn Colour and Leaf-fall of Deciduous Woody Plants
TLDR
It is found that treatment of some intact deciduous woody plants with gibberellic acid markedly influences development of autumn foliage colour and leaf-fall. Expand
Prolonging Dormancy in Vitis vinifera with Gibberellin
TLDR
Since gibberellin has been reported to break the dormancy of buds in peach and potato, and of epicotyls in the tree peony4, it was tested for this purpose on grapes. Expand
