Pollination Vs. Fertilization

Pollination Pollination is the process by which pollen is transferred in plants, thereby enabling fertilization and sexual reproduction.pollenplants fertilizationsexual reproduction

Fetilization After the pistil is pollinated, the pollen grain germinates in a response to a sugary fluid secreted by the mature stigma (mainly sucrose). From each pollen grain, a pollen tube grows out that attempts to travel to the ovary by creating a path through the female tissue.pistilpollinatedpollen tube

Once fertilized, the ovary becomes the Fruits. The purpose of the ovary is to carry and nourish the seeds. Once Fertiized, the ovule becomes the seeds.

Self pollination Few plants actually self pollinate. The mechanism is seen most often in some legumes like peanuts and soybeans.

Cross-Pollination Cross-pollination, also called allogamy occurs when pollen is delivered to a flower from a different plant. Plants adapted to outcross or cross-pollinate often have taller stamens than carpels or use other mechanisms to better ensure the spread of pollen to other plants flowers.allogamy

Cross-pollination

Hybrids A hybrid is the combination of two or more different things, aimed at achieving a particular objective or goal.

“True to Seed” Seeds collected from a plant will be an exact copy of that plant! Very few plants are true to seed.

“True to Type” That means seed collected from plants from this season, when germinated and grown next season, will produce plants that are same type to the plants that the seeds were collected from. Most must be done through cuttings of the plant

Here’s How You Really Get Sowin’

Largest Seed in the World Coco de Mer A single seed may be 12 inches (30 cm) long, nearly three feet (0.9 m) in circumference and weigh 40 pounds (18 kg)

Smallest Seed in the World Microscopic view of the seed of a coral- root orcid (Corallorhiza maculata). The individual seed is only about 0.2 mm in diameter. In fact, there are unusual bacterial cells that are larger than this orchid seed.

Germination Rate Number of seeds that will make into a viable plant. You want to get a 75% germination rate out of most plants. But some won’t!

Stratification stratification is the process of pretreating seeds to simulate natural winter conditions that a seed must endure before germination. Many seed species undergo an embryonic dormancy phase, and generally will not sprout until this dormancy is broken.

Scarification Seed coat (external dormancy) results from a seed's hard seed coat that is impervious to water and gases. The seed will not germinate until the seed coat is altered physically.
