The leaf angle distribution (or LAD) of a plant canopy refers to the mathematical description of the angular orientation of the leaves in the vegetation. Specifically, if each leaf is conceptually represented by a small flat plate, its orientation can be described with the zenith and the azimuth angles of the surface normal to that plate.
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.
A leaf area index (LAI) expresses the leaf area per unit ground or trunk surface area of a plant and is commonly used as an indicator of the growth rate of a plant. LAI is a complex variable that relates not only to the size of the canopy, but also to its density, and the angle at which leaves are oriented in relation to one another and to ...
The following terms are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflets). [1] The edge of the leaf may be regular or irregular, and may be smooth or have hair, bristles, or ...
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 ...
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.
