EFFECT OF LATITUDE TO DAYS OF GROWTH PERIOD FOR SOME WINTERNESS VARIETIES OF WHEAT IN REGIONS OF LOW ELEVATION ON THE INLAND OF CHINA |

| Abstract: | Dongfanghong 3, xindong 2 and Taishan 4 belong in a type of win-terness varieties of wheat. The ecological experiments of wheat sowingstages in autumn were arranged on Beijing, Shijiazhuang, Jinan, Yanc-heng and Hefei at 10/8 (month/day) for about during 1982-1985. Theselocalities are distributed in regions of low height above sea level on theinland of China. Their latitudes are 39°8', N, 38°4'N, 36°1'N, 33°5'Nand 31°1'N, respectively. The experiment results showed that daysof growth period from sowing to maturation for winterness varieties ofwheat were reduced or prolonged 2-3 days in pace with latitude wasmoved 1 degree to the south or to the north. |
