Gingko die before turning to be yellow

Every year, gingko turn to be yellow in this season. Streets look like it’s covered with yellow carpet.

However, in Yokohama,gingko is dying before turning to be yellow.

Even only in Yokohama,most of the gingko have their leaves wither and die quietly.

From the research on twitter, in Kamakura, Chiba, gingko is dying in the same way.

Back in September,I posted about withering plants.

I suspected it might be because of brine damage but typhoons come every year.

There is no outstanding change of environment for plants this year.

Pine, other acicular tree, and bamboo are withering as well.

We hope to know if the similar phenomena was observed in Chernobyl too.

  1. Maybe something to do with the watertable or the ability of the tree to absorb water as here in England i have several in pots and wheras the smaller plants in 3″ pots were quite moist at the roots throughout the growing season and maintained a green leaf before turning yellow another grafted specimen in a large wooden trough got a bit dry at the roots during the summer and the first leaves to emerge became crisp at the edges and eventualy half the leaf became a dead brown before the remainder of each leaf turned yellow.I pruned the ends of some shoots after these first leaves emerged and where it made a second flush of leaves they were green and did not turn brown like the previous spring flush.

    Is there a mechanism whereby radioactive pollutants prevent the sufficient uptake of water in mature trees?

    Clearly the images show something is amiss and saline grounwater may be worth investigating but so are other possibilities.

    You would not want to be making beverages of leaves if the tree has been dumping Caesium,Strontium,maybe even other ‘elements’ such as Francium into it’s leaves

  2. Maybe you can email the person who runs this website “The Ginkgo Pages” http://kwanten.home.xs4all.nl/

    She does have some interesting information on these trees…
    “Due to its natural resistance to diseases, insects, air pollution, fire and even radioactive radiation it is also used as a street tree in cities and urban areas. It is also planted in parks and along boulevards because of its unique form and yellow leaf colour in fall. For instance in Japan many are planted in parks and along avenues, esp. in Tokyo.”
    and
    “Hiroshima:A-bombed Ginkgo
    At the end of World War II on August 6th 1945 an atomic bomb was dropped on Hiroshima by the Americans. The plants and trees in the area around the epicentre were examined in September 1945.
    The Ginkgo situated near a temple about 1.1 km away from the blast center appeared to bud after the blast without any major deformations (the temple itself was destroyed). The temple-site in Housenbou was smaller after the war and they considered transplanting or cutting down the Ginkgo to rebuild the temple. In 1994 it was decided to leave it there and adjust the temple to it, so now the main building has stairs in front divided into left-and right hand sides, protecting the Ginkgo inside this U-shape.
    Engraved on it “No more Hiroshima” and people’s prayers for peace.

    Six atomic bombed Ginkgo trees are still alive.”

  3. Yes, gingkoes in Hiroshima survived the blast; but the atomic nucler bomb released more heat, but far less radioactivity than the nuclear accidentof Fukushima (some experts say may be 30 times Hiroshima).
    Gingkoes are gymnosperms like the pines who died from radiations in Chernobyl (see “red forest” in Chernobyl).
    And there is cesium and strontium in soil and water; gingkoes can fix these radionuclides instead of potassium and calcium.

About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
