Quaking aspens reproduce via sexual and asexual reproduction. Sexual reproduction is rare because conditions have to be just right for the seeds to germinate and survive. Aspens are dioecious, meaning that the male and female organs are carried on different individuals, but there seems to be a majority of male plants. Quaking aspens first flower when they are 10-20 years old and reach a production peak around 50 years old. The flowers are in a catkins ( The flowers are pollinated by the wind, and the seeds are also dispersed by the wind, some up to several minds. The seeds can also be scattered by water in aquatic environments. A single quaking aspen can produce 1.6 million seeds every year, and larger crops are produced in 2-3 or 4-5 year intervals. The seeds can only survive with suitable temperatures (39-98 degrees Fahrenheit), nutrient-rich soil, and plenty of water. Seedlings produced by sexual reproduction provide diversity in an otherwise genetically identical or similar colony of trees. [http://www.rook.org/earl/bwca/nature/trees/populustrem.html] | |||
