Wind Pollination

Wind pollination is the transfer of pollen from a flower’s anther to a compatible stigma by air currents, a reproductive strategy that allows plants to reproduce without animal pollinators. Wind-pollinated plants typically produce abundant, lightweight pollen, release it from exposed anthers, and present large or feathery stigmas that intercept airborne grains; flowering structures often reduce barriers to air movement. This process is common in grasses, many trees, and some crop plants, including maize and wheat. Understanding wind pollination helps explain plant distribution, flowering ecology, crop breeding, and seasonal airborne pollen patterns that can affect respiratory health.

Pollination and Flower Structure

0 Views •

2020

Flowers are the reproductive, seed-producing structures of angiosperms. Typically, flowers consist of sepals, petals, stamens, and carpels. Sepals and petals are the vegetative flower organs. Stamens and carpels are the reproductive organs. Flowers must be pollinated to produce seeds. In angiosperms, pollination is the transfer of pollen from the anther of the stamen (the male structure) to the stigma of the carpel (the female structure). Flowers may be self-pollinated or cross-pollinated.

2016

To reveal the pollinator effectiveness of a given plant species, multiple methods of field experiments have been developed. This study demonstrates the basic methods of field experiments for pollination ecology using the case study of Lycoris sanguinea var. sanguinea and the novel pollination mechanism, breaking-bud pollination.

Three-Winding Transformers

Three identical single-phase transformers can be configured to form a three-phase transformer connection, which involves high-voltage and low-voltage windings. The high-voltage windings are denoted by capital letters A-B-C, while the low-voltage windings are labeled with lowercase letters a-b-c, representing their respective phases. This notation helps distinguish between the high and low voltage sides of the transformer. In the per-unit equivalent circuit of a grounded Y-Y three-phase...

Source: Jose Roberto Moreto and Xiaofeng Liu, Department of Aerospace Engineering, San Diego State University, San Diego, CA Wind tunnel tests are useful in the design of vehicles and structures that are subjected to airflow during their use. Wind tunnel data are generated by applying a controlled air flow to a model of the object being studied. The test model usually has a similar geometry but is a smaller scale compared to the full-sized object. To ensure accurate and useful data is collected...
