Sun Lianfa; Qi shiyu; Xiao Zhimin and Liu Wei (Crop Breeding Institute,Heilongjiang Academy of Agricultural Sciences)  
The test was carried out in greenhouse to investigate the effect of light length and pattern on growth process of spring wheat. The results showed that the breaking of dark period promoted the growth processes of different photosensitive spring wheats,displaying obvious long- light effect; the long- light effect was more clear in photosensitive materials than in photoinsensitive ones;and the light - time needded to finish photostage was different among light patterns:mote in long- light and less in dark - period breaking.
