为了研究猕猴和叶猴掌面平均花纹强度(API)的种属间差异,运用SPSS 11.0 for Win-dows统计软件,对太行山猕猴(55只)、藏猴(19只)、山魈(52只)、日本猕猴(74只)、食蟹猕猴(112只)、黑叶猴(13只)、菲氏叶猴(7只)的左侧掌面上6个主要花纹区(...为了研究猕猴和叶猴掌面平均花纹强度(API)的种属间差异,运用SPSS 11.0 for Win-dows统计软件,对太行山猕猴(55只)、藏猴(19只)、山魈(52只)、日本猕猴(74只)、食蟹猕猴(112只)、黑叶猴(13只)、菲氏叶猴(7只)的左侧掌面上6个主要花纹区(Hp,Th,指间Ⅰ-Ⅳ区)的平均花纹强度值进行统计分析.结果表明,同科不同种属间具有共性,也具有一定的差异性;灵长类掌面的花纹强度不仅是由遗传因素所决定的,同时还与他们的生活方式和生活环境有关.展开更多
A comparative study on the photosynthetic parameters among intergeneric progenies derived from \%Oryza sativa\% L.×\%Sorghum vulgare\% L., its maternal parent Gui 630 and commercial 3\|line hybrid rice Shanyou 63...A comparative study on the photosynthetic parameters among intergeneric progenies derived from \%Oryza sativa\% L.×\%Sorghum vulgare\% L., its maternal parent Gui 630 and commercial 3\|line hybrid rice Shanyou 63 in pot experiment in greenhouse was conducted. The morphological and photosynthetic characters of canopy leaves and chlorophyll fluorescence kinetic parameters including \%F\%\-v/\%F\%\-m, \%F\%\-v/\%F\%\-0, photochemical quenching coefficient and non\|photochemical coefficient of canopy leaves of 3 varieties were measured. The results showed the progeny, Yuanyou 1, derived from an intergeneric cross of rice and sorghum possesses better canopy spatial architecture with thicker, heavier and bigger canopy leaf than its maternal parent Gui 630. Higher photosynthetic rate due to higher chlorophyll content, higher primary energy transformation efficiency, potential of PSII and non\|photochemical quenching coefficient (\%q\%\-E) were also measured in Yuanyou 1. These explain partly why the intergeneric progeny has higher biomass production, and better tolerance to adverse conditions and higher field yields even under stress conditions.展开更多
