Determination of plant alkaloid content
Alkaloids are natural nitrogen-containing organic compounds, but do not include amino acids, proteins, nucleic acids, chlorophyll, choline, methylamine and othe
Observations on the basic structure and posterior contents of plant cells
Cells are the basic units that make up living organisms. Compared with animal cells, plant cells have their own special cell components, such as cell wall and p
In vivo observation of the microfilament skeleton of plant cells
In a broad sense, the cytoskeleton is a type of organelle that contains three different components: microtubules, microfilaments, and intermediate fibers. So fa
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
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
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
Fluorescent labeling and observation of plant organelles
Plant cells contain abundant organelles, including vesicles, plastids, mitochondria, Golgi apparatus, ribosomes, endoplasmic reticulum, microtubules and microfi
Artificially induced conifer trauma Formation of resin canals
Conifers are a group of gymnosperms with slender, needle-like leaves, mostly evergreen, and generally soft, some resin-containing material, consisting mainly of
