Larger floral displays increase pollinator visitation as well as among-flower self-pollination (geitonogamy) in self-compatible species. Dichogamy (temporal separation of gender expression) can limit geitonogamy and increase outcrossing but this depends on pollinator behavior within inflorescences. Declining nectar volume from lower to upper flowers is a hypothesized adaptation to increase outc...

Flowering plants have developed many ways to arrange their flowers. A flower-bearing branch or system of branches is called an inflorescence. The number of flowers that an inflorescence contains ranges from a single flower to endless flower-clusters. Over the past centuries, botanists have classified inflorescences based on their morphology, which has led to an unfortunate maze of complex botan...

the close to impossible correct controlling of the temperature and light intensity is the main limiting factors of growing plants in the plastic covered greenhouses. quality and vase life of cut flowers are mostly influenced by greenhouse temperature. alstroemeria needs cold temperature for growth and flowering. in the current study, the such changes in vase life and flower quality as stem leng...

A breeding program has been developed since 1994 (done by Dr A. Trigui), by controlled pollinations of the Tunisian olive oil variety Chemlali Sfax in order to improve the qualities of this variety (higher oil percentage and a better chemical composition). These controlled pollinations have produced a population of new genotypes presented a wide genetic diversity which was very interesting for ...

Curcuma heyneana or temu giring is mainly popular for medicinal and beauty purposes; however due to its attractive inflorescence, it potential ornamental plant. This study aims describe morphological characteristics examine gamma irradiation effect on plant growth of C. heyneana. The method applied was acute irradiation, with 6 doses 0 Gy (control), 10 Gy, 20 30 40 50 Gy; 3 replications, 15 rhi...

• Flower formation in grapevines follows 3 steps: 1) formation of uncommitted primordia, also called anlagen, within the latent buds; 2) differentiation of uncommitted primordia into inflorescence primordia; and 3) differentiation of inflorescence primordia into individual flowers . Steps 1 and 2 happen during the previous season, whereas Step 3 does not happen until budbreak of the current sea...

Abstract The variability of metric traits has been studied in 20 Kazakhstan populations three Nitraria species ( N. schoberi L., sibirica Pall., and komarovii Iljin & Lava ex Bobrov). According to the results, differs from small leaves, fruits, seeds, as well structural features inflorescences flowers. is characterized by a greater number flowers per inflorescence (25–66 on average) than (1...

We experimentally reduced the number of flowers of two species of Heliconia (H. caribaea and H. bihai) by 50% on territories defended by male Purple-throated Caribs (Eulampis jugularis). Following reductions, males decreased the amount of time they spent feeding on their territories and lost a significant amount of weight, but increased their time feeding and regained weight to premanipulation ...
