Comparative study of cold resistance characteristics in seven Indocalamus spp .

Abstract: Diurnal changes of a chlorophyll fluorescence with low temperature stress at night were studied using the chlorophyll fluorescence technique to determine cold resistance in seven Indocalamus spp .Results indicated that diurnal changes of the actual photochemistry quantum yield for PS Ⅱ was approximately W-shaped .Also , parameters , such as the photochemistry efficiency of PS Ⅱ (Fv / Fm), latent activeness of PS Ⅱ (Fv /Fo ), and Yield of I .guangdongensis , were lower than other Indocalamus spp .I .pumilus had the largest initial fluorescence (F o)and fluorescence (Fm)with Fv / Fm and Fv / F o of I .barbatus being higher than several other Indocalamus spp .This indicated that I .guangdongensis more readily suffered from low temperature stress and therefore had weak cold resistance .However , the cold resistance of I .pumilus and I .barbatus was comparatively stronger .Thus , it is feasible to test cold resistance of different Indocalamus spp .with the chlorophyll fluorescence analysis technique .[ Ch , 4 fig .3 tab .15 ref .]
