From The Fig Tree Turning Green Desk:
On August 23rd, 2021, Arava Institute staff harvested three bunches of dates from our world-famous ancient date palms. This is the second year of harvesting fruit from this previously extinct tree, brought back to life by Dr. Elaine Solowey.
This year’s harvest from Hannah produced almost 700 dates (after 111 during last year’s first harvest), which were pollinated by Methuselah and two other ancient date palms named Adam and Jonah. The dates’ flavor is similar to medjool, semi-dry with honey tones.
These unique dates are currently being kept cool in storage. Later this fall, the Arava Institute plans to offer a limited number of dates for sale at the Kibbutz Ketura guesthouse.
Hannah was sprouted from a 2,000 year-old seed, and pollinated by another Ancient Judean date tree. Dr. Elaine Solowey, director of the Center for Sustainable Agriculture of the Arava Institute, and Dr. Sarah Sallon, director of the Louis L. Borick Natural Medicine Research Center of Hadassah Hospital, harvested these ancient dates in the culmination of an ambitious, decades-long experiment to raise the biblical-era Phoenix dactylifera – date palm – from the dead.
During Yigal Yadin’s excavations of Masada in the mid 1960’s, ancient date seeds were discovered beneath rubble at the Northern Palace approach. After being kept in storage for over 40 years, a project initiated by Dr. Sallon, aimed to germinate ancient seeds found on archaeological sites in an effort to reintroduce extinct plants previously grown in the region. As part of this endeavor, Dr. Solowey succeeded in germinating one of these ancient date seeds in 2005, initially thought to be botanically impossible. Dubbed Methuselah it was the oldest seed ever grown attracting wide international attention.
After the successful germination of the first seed, Dr. Solowey and Dr. Sallon took to replicating the experiment. 32 additional intact seeds were chosen, out of which 6 sprouted. The seeds were germinated by warming and hydrating them slowly and gradually. They were then dosed with Gibberellic acid, a growth-promoting plant hormone, and enzymatic fertilizer.
In early 2019, three of the six trees named by Dr. Solowey Adam, Jonah and Hannah were moved out of their greenhouse home to be planted outdoors at the Arava Institute’s Daniel Fischel & Sylvia Neil Research & Visitors’ Park.
The first tree, Methuselah, was discovered to be male. Luckily two of the subsequent trees were revealed by DNA testing as females, and one of them, Hannah, has borne one bunch with 111 dates, which were harvested in early September. Some of the fruit were tasted, and some were sent for further research.
The experiment seeks to rediscover the origins of the historic date palm population and confirm the date seeds’ long-term durability, while shedding light on ancient cultivation techniques that nurtured this unique fruit and exploring its potential relevance for modern date agronomy.
It seems that when YHVH promised to bring back Israel, He also meant the trees.
