Note from Les Hannibal, 4/6/1999

Crinum moorei pollen: There is nothing wrong with it when you breed Amarcrinum in 70 degree F weather. It's plenty potent. It is the higher temperatures that are a problem.

CybeRose note: It is important to remember that pollen tubes are living plants, though very tiny, that have their preferred conditions for growth. Plants that are normally pollinated at night by moths or bats can be expected to have pollen tubes that grow best at lower temperatures — appropriate to the nights of their native homes. To the contrary, plants that are normally pollinated during hot summer days will usually have pollen tubes that favor heat. To raise hybrids between species of such different adaptations, we must make allow for the differences. See Takatsu et al. Temperature and gladiolus pollination (2001)
