Can the seeds be too old?
Not if they are to be used to plant but (Phoenix dactylifera).
According to the media ScienceAlert, we succeeded in researchers to grow six but with ancient daddelfrø, which was found in a desert near Jerusalem. It writes Science.dk, where you can see more photos of the budding but.
the Seeds are some of the oldest ever to germinate, and they are just a few among several hundred finds in a cave and in a prehistoric palace, which was built by Herod The Great.
in Order to get the seeds to germinate was the steeping and added hormones, which gives the seeds an extra boost on the road.
In all, planted the researchers, led by Sarah Sallon of Hadassah university Hospital in Jerusalem, 32 seeds, 6 germinated.
the Study throws light on daddelpalmens origin, which suggests that its cultivation began with the local or eastern variants of the variety, which only later became mixed with the flavors from the west, writes the researchers in the study according to ScienceAlert, writing Science.dk.
With the seedlings, it was possible for the researchers to perform analyses, they could not do on the daddelfrøene alone.
And by using the carbon-14 dating (scientific method for dating of archaeological and geological samples), it was possible for the researchers to determine that daddelfrøene is approximately 2,000 years old.
in Addition throws the analyses a light on how the palm trees have been grown and sold.
- As it is described by classical writers as Theofrastos, Herodotus, Galen, Strabon, Pliny the elder and Josephus were palm plantations valuable and produced dates in different variations, including the quality, size, nutritional content, sweetness and shelf life, which made it possible to export them throughout the Roman empire, write the researchers in the study.
the Researchers explains that it is described in the texts, how some of dadlerne was up to 11 centimeters long, and their analysis estimates that the seed was 30 per cent higher then than they are today.
It can also mean that the fruits were larger then than they are today.
As many planteentusiaster may know, the quality of seeds deteriorated with time.
Therefore, the researchers hope the new findings to learn how 6 of the 32 seeds, almost miraculously sprouted after nearly 2,000 years.
