摘    要:利用14 C同位素示踪技术研究了冬小麦越冬期间的光合特性及其对冬小麦生长发育的影响。结果表明 ,越冬期间的冬小麦能够吸收、同化14 CO2 ,并进行转运 ;其同化产物的 60 %用于越冬期的呼吸消耗 ,约 40 %用于返青后的生长发育 ,其中少量的光合产物参与了穗部产量的形成。

关 键 词:冬小麦    越冬期    光合作用    14C同位素示踪

PHOTOSYNTHESIS AND ITS EFFECTS ON GROWTH OF WINTER WHEAT DURING WINTER
Abstract:The photosynthetic characteristic and its effects on growth of winter wheat in winter were studied by using 14 C tracer. The results indicated that plant of winter wheat was able to absorb and assimilate 14 CO\-2,meanwhile to transport its assimilated product from leaves to stems and roots. Nearly 60% of assimilated product was respired out in winter, and about 40% of it was contributed to the growth and breathing of plants after winter, of which a few was applied to the yield formation of spikes.
Keywords:winter wheat  winter  photosynthesis  " target="_blank">14C-tracerzz')" href="#">        14C-tracer
