Children of Chernobyl
We have received many letters from people who read the report and then sent generous donations and requested further information. On behalf of the children — and everyone involved in CCOC’s lifesaving work — you have our eternal gratitude for the great mitzvah you have done in bringing the Chernobyl situation to the attention of your readers. The end result is that the lives of more Jewish children will be saved. Thank you.
Abi Raichik In a recent issue, you state: “Researchers teach that . . . leaves look green in the spring and summer . . . Chlorophyll keeps leaves green, which hides their real colors until autumn” (Odds & Ends, Sept. 1999). Which researchers? Can you quote one or name an exact reference? Actually, the opposite is true. Trees are green in the summer because there is little or no pigment present besides chlorophyll. In trees that have a lot of pigment all season, such as Crimson King maple, the chlorophyll is almost completely hidden. In the fall, the warm sunny days and cold nights stimulate the production and storage of sugar. Leaf pigment in trees that “turn” is a byproduct of sugar production. Moreover, you write that leaves fall off in autumn because they lack a supply of chlorophyll and that they “weaken.” Actually, leaf fall in deciduous trees is not directly related to the production of chlorophyll and has nothing to do with weakness. Prompted by changing day length, the tree sets up a layer of cork cells along a line at the base of the leaf stem. This line is called the abscission layer. When the cork layer is complete, the leaf falls off. If you look at newly fallen leaves, they will look strong and healthy, unless disease or weather has damaged them. I hope you will print a correction.
