Bacaba produces more fruits than any other palm in central Amazonia, averaging around 2500 per bunch. Bunches usually weigh about 3–4 kg, but can weigh up to 10 kg. The fruit is a drupe weighing up to 3.0 grams. Propagation is by seeds that germinate in 60–120 days, with slow growth.
The oldest viable seed that has grown into a full plant was a roughly 2,000-year-old Judean date palm seed, recovered during excavations at Herod the Great's palace on Masada. It had been preserved in a cool, dry place, not by freezing.
It is slow growing, but will eventually reach heights of 6 to 18 metres. Under natural conditions, it grows as a solitary tree. Germination of the seeds is erratic. The closely related Belmore sentry palm (Howea belmoreana), also endemic on Lord Howe Island, is a smaller species to 7 metres tall, found mainly as an understorey plant in moist ...
The Judean date palm at Ketura, Israel, nicknamed Methuselah. The Judean date palm is a date palm (Phoenix dactylifera) grown in Judea.It is not clear whether there was ever a single distinct Judean cultivar, but dates grown in the region have had distinctive reputations for thousands of years, and the date palm was anciently regarded as a symbol of the region and its fertility.
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 ...
Nīkau make an excellent potted plant, and are quite hardy. They tend to be slow-growing. They grow readily from seed if the fruit is soaked in water for a few days and then gently scrubbed to remove the flesh. The seed will then germinate readily if placed in sealed plastic bags in partial shade, after which they can be planted in deep pots.
It is a measure of germination time course and is usually expressed as a percentage, e.g., an 85% germination rate indicates that about 85 out of 100 seeds will probably germinate under proper conditions over the germination period given. Seed germination rate is determined by the seed genetic composition, morphological features and ...
Socratea exorrhiza, the walking palm or cashapona, is a palm native to rainforests in tropical Central and South America. It can grow to 25 metres in height, with a stem diameter of up to 16 cm, [1] but is more typically 15–20 m tall and 12 cm in diameter. [2] It has unusual stilt roots, the function of which has been debated.
