Angiosperm Flower Patterns and Flower Programs
In order to illustrate in a simple way the structure of a flower, the composition, arrangement and interrelationship of its parts, the parts of a flower can be
Determination of the content of plant flavonoid compounds
Usually, we call a group of substances with C6-C3 C6 carbon structure as flavonoid compounds, including flavones, flavonols, flavanones, chai- cones, anthocyani
Fluorescent labeling and observation of plant organelles
Plant cells contain abundant organelles, including vesicles, plastids, mitochondria, Golgi apparatus, ribosomes, endoplasmic reticulum, microtubules and microfi
Detection of pollen viability and stigma pollinability
The pollination process begins with anther dehiscence and dispersal of mature pollen. Pollen grains carrying male gametes or their precursors are exposed to dry
Directional growth of plant pollen tubes to ovules
Since the sperm cells of angiosperms are unable to move, the completion of sexual reproduction in angiosperms requires the use of pollen tubes to deliver the sp
TUNEL assay for programmed cell death in plants
Programmed cell death (PCD) is a genetically regulated process that actively removes excess, injured cells during plant growth and development or in response to
Observations on pollen germination and pollen tube growth in vitro
After landing on the stigma, pollen, the male gametophyte of plants, grows pollen tubes through germination and transports sperm cells to the embryo sac to comp
Plant chromosome karyotyping
Various organisms in nature have relative stability in the form, structure and number of their chromosomes. The complete set of chromosomes contained in the gam
