Southern hemisphere plants show more delays than advances in flowering phenology [PDF]
Journal of Ecology, 2023 Shifts in flowering phenology have been studied in detail in the northern hemisphere and are a key plant response to climate change. However, there are relatively fewer data on species' phenological shifts in the southern hemisphere.

Phenology of Pilosocereus leucocephalus (Cactaceae, tribe Cereeae): a columnar cactus with asynchronous pulsed flowering [PDF]
Plant Ecology, 2010 Pilosocereus leucocephalus produces flowers in discrete pulses, suggesting this cactus might exhibit pulsed flowering?a rare flowering pattern among angiosperms. In this study, we (1) describe the phenology of P.

Synchronous pulsed flowering: analysis of the flowering phenology in Juncus (Juncaceae). [PDF]
Annals of Botany, 2007 The timing of flowering within and among individuals is of fundamental biological importance because of its influence on total seed production and, ultimately, fitness. Traditional descriptive parameters of flowering phenology focus on onset and duration of flowering and on synchrony among individuals.

Skewness in bee and flower phenological distributions
Ecology, 2022Abstract Phenological distributions are characterized by their central tendency, breadth, and shape, and all three determine the extent to which interacting species overlap in time. Pollination mutualisms rely on temporal co‐occurrence of pollinators and their floral resources, and although much work has been done to characterize the ...

Phenology of Sorghum Flowering
Crop Science, 1994Understanding the phenology of flowering, the time when sorghum, Sorghum bicolor (L.) Moench, is vulnerable to oviposition by the sorghum midge, Contarinia sorghicola (Coquillett), would improve the capability of managing this key sorghum insect pest and aid in developing control recommendations.

PHENOLOGY OF FLOWERING AND NUT PRODUCTION IN MACADAMIA
Acta Horticulturae, 2002Macadamia is an Australian native tree that produces a highly valued, edible kernel. Quantitative information on the phenology of flowering and nut-drop in this species will assist orchard design and management of production orchards and breeding programmes.

Flowering phenology, flower sterility and pollen germination in olive cultivars
Acta Horticulturae, 2019Olive (Olea europaea L.) orchard productivity largely depends on the choice of planted cultivars and their reproductive traits. Simultaneous flowering periods enable cross-pollination and high fruit set in different cultivars. Olive tree is producing both perfect (hermaphrodite) and staminate (male) flowers.

Heteroblasty and the Evolution of Flowering Phenologies
International Journal of Plant Sciences, 1999Flowering phenologies have rarely been examined from a developmental perspective. The production of a flower or inflorescence, however, is an integral part of the ontogeny and architecture of an organism. As a result, basic features of plant developmental morphology have the potential to define options for variation in phenology and to determine, in ...
