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.

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 ...

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.

Flowering phenology as a functional trait in a tallgrass prairie
New Phytologist, 2011• The timing of flowering is a critical component of the ecology of plants and has the potential to structure plant communities. Yet, we know little about how the timing of flowering relates to other functional traits, species abundance, and average environmental conditions. • Here, we assessed first flowering dates (FFDs) in a North American tallgrass

Phenology of Entomophilous Flowers
Ecology, 1924The statements made here are based upon observations, from i884 to 19I3, of 470 indigenous and 54 introduced entomophilous flowers. Twentythree more native and seven introduced species, with an average of five days, are excluded as fragmentary. The time of each flower includes early dates for early seasons and late dates for late seasons, and is ...

A phenological mid-domain effect in flowering diversity
Oecologia, 2004In this paper, we test the mid-domain hypothesis as an explanation for observed patterns of flowering diversity in two sub-alpine communities of insect-pollinated plants. Observed species richness patterns showed an early-season increase in richness, a mid-season peak, and a late-season decrease. We show that a "mid-domain" null model can qualitatively

Flowering phenology and compensation for herbivory in Ipomopsis aggregata
Oecologia, 2003The mechanisms and circumstances that affect a plant's ability to tolerate herbivory are subjects of ongoing interest and investigation. Phenological differences, and the timing of flowering with respect to pollinators and pre-dispersal seed predators, may provide one mechanism underlying variable responses of plants to herbivore damage.

Phenological Variation in Flowering and Fruiting of Asclepias
American Midland Naturalist, 1987Phenological studies of flowering and fruiting in experimental plots and in field sites demonstrated variation within and between populations of Asclepias incarnata, A. verticillata and A. syriaca. Flowering of A. incarnata and A. verticillata occurred in July and August, and overlapped at least 30 days. In contrast, A.
