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.
Can produce multiple harvests outdoors in one season [19] Can be grown in areas of high light pollution without preventing flowering or causing hermaphroditism; Most autoflowering seeds available in the market are feminised. Only a few brands offer regular autoflowering seeds.
It is uncommon for pathogens to be transmitted from the plant to its seeds (in sexual reproduction or in apomixis), though there are occasions when it occurs. [2] [page needed] Seeds generated by apomixis are a means of asexual reproduction, involving the formation and dispersal of seeds that do not originate from the fertilization of the embryos.
Apomixis (self-cloning), where seeds are produced asexually and the new plant is genetically identical to its parent; The mode of reproduction of a crop determines its genetic composition, which, in turn, is the deciding factor to develop suitable breeding and selection methods. Knowledge of mode of reproduction is also essential for its ...
Woody growth form Lamiaceae are more pollen-limited and thus produce fewer seeds and seeds of lower quality, thus favoring the female herbaceous growth form. [12] Gynodioecy is rare because some sexual systems are more evolutionarily liable to change in certain lineages in comparison with others.
About 15% produce gametes but are principally self-fertilizing with significant out-crossing lacking. Only about 8% of higher plant species reproduce exclusively by non-sexual means. These include plants that reproduce vegetatively by runners or bulbils, or which produce seeds without embryo fertilization . The selective advantage of ...
Reproducing through seeds is the most widespread method of reproduction in both monocots and dicots. However, internal seed structure is vastly different between these groups. The cotyledon is the embryonic leaf within a seed; monocots have one whereas dicots have two. The evolution of having one or two cotyledons may have arisen 200-150 Mya ...
It has been reported that plant hormones provided by the ovary seed (such as auxins and gibberellins) promote fruit set and growth to produce seedless fruits. Initially, without seeds in the fruit, vegetative propagation was essential. However, now – as with seedless watermelon – seedless peppers can be grown from seeds. [citation needed]
