Vivipary

Similarly, some Crassulaceae, such as Bryophyllum, develop and drop plantlets from notches in their leaves, ready to grow.

[1] This phenomenon occurs most frequently on ears of corn, tomatoes, strawberries, peppers, pears, citrus fruits, and plants that grow in mangrove environments.

[citation needed] In some trees, like jackfruit, some citrus, and avocado, the seeds can be found already germinated while the fruit goes overripe; strictly speaking this condition cannot be described as vivipary[citation needed], but the moist and humid conditions provided by the fruit mimic a wet soil that encourages germination.

This is thought to be an adaptation to rapid photoperiod, or daylight changes, since Escobaria vivipara is one of the few cacti that naturally occurs above the frost line in Canada.

[5] Vivipary includes reproduction via embryos, such as shoots or bulbils, as opposed to germinating externally from a dropped, dormant seed, as is usual in plants;[6][7] A few plants are pseudoviviparous – instead of reproducing with seeds, there are monocots that can reproduce asexually by creating new plantlets in their spikelets.
