Flower of tea; or, pekoe flower

Anthocyanins from red flower tea (Benibana-cha), Camellia sinensis.

Three anthocyanins were isolated from the leaves of red flower tea (Benibana-cha), Camellia sinensis, and their structures were determined by means of chemical and spectroscopic analyses. Two are the anthocyanins, delphinidin and cyanidin 3-O-beta-D-galactosides, respectively. Whereas the third, delphinidin 3-0-beta-D-(6-(E)-p-coumaryl)galactopyranoside. The anthocyanins were also contained in ...

Postharvest Assessment of Lignifying Enzymes Activity, Flower Stem Lignification and Bending Disorder of Gerbera Cut Flower

Scape bending disorder is the most important factor affecting postharvest loss of gerbera cut flowers. One of the ultimate reasons for gerbera stem bending is lignin, with deformation structural functions and defensive mechanisms. This postharvest experiment was conducted to evaluate the role of phenylalanine ammonia lyase (PAL) and peroxidase (POD) enzymes activity in stem bending of two gerbe...

Flower development

Plants that bear flowers are called Angiosperms. With around 300,000 species, they represent the largest and most successful group in the green kingdom. Flowers contain one or more female organs, or carpels, in their center. Carpels enclose the ovules, and later the seeds. Stamens, the male pollenbearing organs, surround the carpels. Sexual organs are in turn surrounded by vegetative organs (th...
