Imbibition of water through the membrane of the seed shell is the first step in the germination process for cannabis. Dry cannabis seeds are floating, a convenient way to verify a successful imbibition is to put them in water until they sink, which takes about six hours when submerged in an infuser, and about 12 hours when they are floating on ...
Autoflowering cannabis or day neutral cannabis varieties automatically switch from vegetative growth to the flowering stage based on age, as opposed to the ratio of light to dark hours required with photoperiod dependent/short-day strains. Many autoflowering varieties are ready to harvest in less than 10 weeks from seed.
The anoxygenic phototrophic iron oxidation was the first anaerobic metabolism to be described within the iron anaerobic oxidation metabolism. The photoferrotrophic bacteria use Fe 2+ as electron donor and the energy from light to assimilate CO 2 into biomass through the Calvin Benson-Bassam cycle (or rTCA cycle) in a neutrophilic environment (pH 5.5-7.2), producing Fe 3+ oxides as a waste ...
The spores of rust fungi may be dispersed by wind, water or insect vectors. [13] When a spore encounters a susceptible plant, it can germinate and infect plant tissues. A rust spores typically germinates on a plant surface, growing a short hypha called a germ tube. This germ tube may locate a stoma by a touch responsive process known as ...
Cannabis. Cannabis has served as an entheogen —a chemical substance used in religious or spiritual contexts [1] —in the Indian subcontinent since the Vedic period dating back to approximately 1500 BCE, but perhaps as far back as 2000 BCE. It was introduced to the New World by the Spaniards in 1530-1545.
Cannabis (/ ˈkænəbɪs /), commonly known as marijuana (/ ˌmærəˈwɑːnə /), [ 2 ]weed, and pot, among other names, [ 3 ] is a non-chemically uniform drug from the cannabis plant. Native to Central or South Asia, the cannabis plant has been used as a drug for both recreational and entheogenic purposes and in various traditional medicines ...
Scarification in botany involves weakening, opening, or otherwise altering the coat of a seed to encourage germination. Scarification is often done mechanically, thermally, and chemically. The seeds of many plant species are often impervious to water and gases, thus preventing or delaying germination. Any process designed to make the testa ...
Cannabis indica is an annual plant species in the family Cannabaceae [1] indigenous to the Hindu Kush mountains of Southern Asia. [2] The plant produces large amounts of tetrahydrocannabinol (THC) [ 3 ] [ better source needed ] and tetrahydrocannabivarin (THCV), with total cannabinoid levels being as high as 53.7% [ scientific citation needed ] .
