Studies on tambalacoque seed germination by Hill (1941) and King (1946) found that the seeds germinated without abrading. Temple's hypothesis that the tree required the dodo was contested. Others have suggested that the decline of the tree was exaggerated or that other extinct animals, such as giant tortoises , fruit bats , or the broad-billed ...
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. However, the seeds also can ...
Germination of seedlings raised from seeds of eucalyptus after three days of sowing. In agriculture and gardening, the germination rate describes how many seeds of a particular plant species, variety or seedlot are likely to germinate over a given period. It is a measure of germination time course and is usually expressed as a percentage, e.g ...
The second oldest viable seed recorded is a 1,300-year-old sacred lotus (Nelumbo nucifera) recovered from a dry lake bed in northeastern China in 1995. [ 7 ] [ 8 ] A previously unknown species of Commiphora , possibly the source of the biblical medicinal extract tsori , was successfully germinated from a single seed in 2010 and carbon-dated to ...
Species that characteristically produce suckers include elm (Ulmus) [4]: 299 and many members of the rose family such as Rosa, [4]: 285–296 Kerria [4]: 206 and Rubus. [ 4 ] : 258 Bulbous plants such as onion ( Allium cepa ), hyacinths , narcissi and tulips reproduce vegetatively by dividing their underground bulbs into more bulbs.
Plant embryonic development, also plant embryogenesis, is a process that occurs after the fertilization of an ovule to produce a fully developed plant embryo.This is a pertinent stage in the plant life cycle that is followed by dormancy and germination. [1]
ChalkZone is an American animated television series created by Bill Burnett and Larry Huber for Nickelodeon. [1] The series follows Rudy Tabootie, an elementary school student who discovers a box of magic chalk that allows him to draw portals into the ChalkZone, an alternate dimension where everything ever drawn with chalk and later erased comes to life.

Wild-type rice plants have increased germination rates while rmd-1 mutants have decreased germination rates. This was seen when both were germinated in a liquid germination medium. After the germination rates were tested, there was a comparison of the lengths and widths of the pollen tubes between the two plants.
