STUDIES IN THE STORAGE OF CHESTNUTS TREATED WITH GAMMA RADIATION. II
Two varieties of chestnuts were irradiated with relatively high doses of gamma rays, purporting the extension of storage life of the nuts through the inhibition of rooting and sprouting. The materials were treated with the doses of 1.5, 3, and 6 x 10>s4/sup / 6 weeks after harvest and then stored in moist sawdust at 20 deg C. An almost complete inhibiting effect was obtained with all of the doses used regardless of varieties. The contents of ascorbic acid and of reducing sugar were not influenced directly by any dose of irradiation, but the content of non-reducing sugar was affected to some extent. A sharp increase of respiration was found both in the whole nuts and in the cotyledon part of the nuts immediately after irradiation. In the embryonic axis part of the irradiated nuts, the respiration did not show any change for a considerable period after irradiation; it became fairly lower than the control from the time when some control nuts initiated rooting, and the discoloration of this part took place about the same time. There was a rapid increase of rot incidence when the irradiated nuts have been stored for 4 months at 20 deg C. (auth)
