Anthesis (/ænˈθiːsɪs/) is spelled with the letter "a" followed by the letters "n," "t," "h," "e," "s," and "i," and two silent letters "s" in the middle. Its IPA phonetic transcription denotes the pronunciation of the word, which starts with the vowel sound /æ/ followed by the nasal consonant /n/. The /θ/ sound is pronounced as "th" in "thought," and /iː/ represents the long "e" sound. Anthesis refers to the blooming period of a flower, which marks its sexual reproduction.
Anthesis is a biological term that refers to the process of flowering in plants. It is the specific period in the life cycle of a flower when it reaches full maturity and opens up, revealing its reproductive structures. During this phase, the plant's male and female reproductive organs, known as stamen and pistil respectively, are exposed and ready for pollination.
Anthesis is a crucial stage for the plant's reproductive success as it enables the transfer of pollen from the stamen to the pistil. This exchange facilitates fertilization and subsequent seed production, which further aids in the plant's propagation and continuation of the species.
The timing and duration of anthesis varies greatly among different plant species. It is influenced by various factors including environmental conditions such as temperature, light, and humidity levels. Some plants exhibit brief anthesis periods that only last a few hours, while others may have elongated periods lasting several days.
The phenomenon of anthesis is of considerable interest to botanists, ecologists, and horticulturists as it plays a vital role in the study of plant reproductive biology, pollination mechanisms, and floral evolution. Understanding the intricacies of anthesis can aid in crop production, hybridization, and selective breeding, ultimately contributing to the enhancement of agricultural practices and the preservation of floral diversity.
In bot., the opening or bursting of the flower.

The word "anthesis" is derived from the Greek word "anthēsis" (ἄνθησις), which means "flowering" or "blossoming". It is composed of the prefix "anth-" (ἄνθ-) meaning "flower", and the suffix "-esis" (-ησις) indicating "process" or "action". Thus, "anthesis" refers to the period when a flower reaches its full bloom and opens up.
