The Biological Function of Pistils in Cannabis Reproduction
Pistils play an integral role in cannabis reproduction. They are essential in the processes of pollination and fertilization. When a pollen grain lands on the pistil’s stigma, it initiates pollination.
The stigma’s sticky surface is tailored to catch pollen. Once secured, the pollen travels down the style, reaching the ovary. This journey is crucial for fertilizing the ovules within the ovary.
Fertilization leads to seed development. After successful pollination, seeds start forming within the ovary. This is a vital stage for sustaining the cannabis species and ensuring genetic diversity.
Pistils also influence cannabis genetics. During reproduction, genetic material combines from both parent plants. This process allows breeders to develop new strains with unique traits.
In breeding, pistils are central to selecting and refining desirable genetics. Growers monitor pistil traits to ensure optimal plant characteristics. These might include cannabinoid content, resilience, or flavor profiles.
