The flowers of Cannabis sativa plants are most often either male or female, but, only plants displaying female pistils can be or turn hermaphrodite. Males can never become hermaphrodites. [3] It is a short-day flowering plant, with staminate (male) plants usually taller and less robust than pistillate (female or male) plants.
Cannabis is predominantly dioecious, [16] [18] having imperfect flowers, with staminate "male" and pistillate "female" flowers occurring on separate plants. [19] " At a very early period the Chinese recognized the Cannabis plant as dioecious", [ 20 ] and the (c. 3rd century BCE) Erya dictionary defined xi 枲 "male Cannabis " and fu 莩 (or ju ...
Leaves are often more or less palmately lobed or palmately compound and always bear stipules. Cystoliths are always present and some members of this family possess laticifers. Cannabaceae are often dioecious (distinct male and female plants). The flowers are actinomorphic (radially symmetrical) and not showy, as these plants are pollinated by ...
Cannabis sativa, one of three forms of cannabis. [5] Castanea sativa, sweet chestnut. Coriandrum sativum, coriander, also known as cilantro, an annual herb. Crocus sativus, the saffron crocus. Cucumis sativus, the cucumber. Daucus carota subsp. sativus, the carrot, a plant species. Eruca sativa, the rocket or arugula, a leaf vegetable.
[19] [20] Cannabis x intersita Sojak, a strain identified in 1960, is a cross between C. sativa and C. ruderalis. [3] Attempts to produce a Cannabis strain with a shorter growing season are another application of cultivating C. ruderalis. [8] C. ruderalis when crossed with sativa and indica strains will carry the recessive autoflowering trait ...
A flowering cannabis plant. When cannabis is cultivated for its psychoactive or medicinal properties, male plants will often be separated from females. This prevents fertilization of the female plants, either to facilitate sin semilla flowering or to provide more control over which male is chosen. Pollen produced by the male is caught and ...
Seedless cannabis (sin semilla) Seeded cannabis (con semilla)Cannabis sinsemilla (Spanish pronunciation: [sinseˈmiʝa]) also known as sensimilla, sinse or sensi (can be translated into English as seedless cannabis) is the female Cannabis plant that has not been pollinated and therefore does not develop seeds, increasing the concentration of cannabinoids and terpenes.
Environmental stresses sometimes create pollen bearing male flowers on female plants—known as hermaphroditism, "herming", or "hermies". A method used by organic growers and promulgated by the cannabis breeder Soma, is called 'Rodelization', or letting un-pollinated female plants live several weeks longer than the normal harvest time.
