What equipment is needed for cross-pollination of pea flowers?

Sharp tweezers, a bottle of ethanol for sterilization, and labels.

When is the right time to select flowers for cross-pollination?

Select flowers at the bud stage before they fully open.

How do you prepare a flower for receiving pollen?

Remove the petals to expose the anthers and style.

How is pollen applied to the recipient flower?

Use the anthers of a male flower as a paintbrush to apply pollen to the stigma of the recipient flower.

Do you need to bag the flowers after cross-pollination?

No, it's not necessary since they won't be visited by pollinators.

Resumen

TLDRThis video tutorial explains how to effectively cross-pollinate pea flowers. It outlines the necessary equipment and the proper steps for selecting and preparing flowers for pollination. The process includes sterilizing tweezers, selecting a bud-stage flower, carefully removing its petals to expose the stigma, and applying viable pollen from another flower using the anthers. Finally, the flowers are labeled for reference. The guide emphasizes the importance of timing for selecting flowers and how to manually transfer pollen without needing to bag the flowers post-process.

Cronología

00:00:00 - 00:05:57
The demonstration begins with an introduction to the tools needed for crossing peas: sharp tweezers, a bottle of ethanol for sterilization, and labels. The speaker emphasizes the importance of selecting a flower at the right bud stage, as fully opened flowers are already pollinated and unusable. Once a suitable bud is found, the tweezers are used to carefully remove the petals to expose the anthers and the style, revealing the heart of the flower. This process is shown in detail to ensure successful pollination. The speaker then uses pollen from another flower to apply onto the style, which is visible and ready for cross-pollination. Instructions are repeated clearly to ensure understanding, including the identification of the female and male flowers and the precise method to apply pollen. Finally, the tagged flower is labeled to document the cross, concluding the demonstration of creating a crossed pea flower.
