摘要:

为探究功能性彩色稻物质生产与产量的关系,分析功能性彩色稻品质特点,进一步提高彩色稻产量并为推广应用提供参考依据。本试验以8个功能性彩色稻为对象,从生育期、叶绿素相对含量,净光合速率,干物质积累与转运,产量及其产量结构,稻米的蛋白质和主要矿物质元素含量等方面进行分析。功能性彩色稻生育期相对较长,而产量显著低于常规稻,结实率和千粒重较低是其产量低的主要原因;彩色稻叶绿素相对含量(SPAD值)高于常规稻;净光合速率与常规稻相比总体偏低,但差异不显著;功能性彩色稻前期干物质积累与常规稻差异不显著,灌浆期后干物质积累和转运量显著减少;彩色稻糙米蛋白质含量和微量元素Fe、Cu、Mn、Se、Zn含量显著高于对照;彩色稻精米的蛋白质含量高于常规稻,矿质元素含量与常规稻差异不显著。彩色稻后期干物质积累少,茎叶干物质转运不畅是其产量低的主要因素,彩色稻米蛋白质含量显著高于常规稻,而矿物质元素主要存于彩色稻种皮中。

Abstract:

The objectives are to explore the relationship between the material production and yield of functional colored rice, analyze its quality characteristics, and provide reference for further improving the yield and application of colored rice. This experiment took 8 functional colored rice varieties as the research objects, and conducted the analysis from the aspects of growth period, relative chlorophyll content, net photosynthesis rate, dry matter accumulation and transportation, yield and yield structure, and content of protein and main mineral elements. The results showed that the growth period of functional colored rice was relatively long, and the yield was significantly lower than that of the conventional rice. Low seed setting rate and thousand-grain weight were the main reasons for the low yield. The relative chlorophyll content (SPAD value) of colored rice was higher compared with that of the control, while was slightly lower in the net photosynthetic rate, but the difference was not significant. The dry matter accumulation of functional colored rice was not significantly different from that of conventional rice in the early stage, while the dry matter accumulation and transportation were significantly reduced after the filling stage. The content of protein and trace element Fe, Cu, Mn, Se and Zn of colored brown rice were significantly higher than those of the control. The protein content of colored milled rice was higher than that of the conventional rice, while the contents of mineral elements were not significantly different. The dry matter accumulation of colored rice was less in the later stage, and the poor transport of dry matter in stems and leaves was the main factor of the low yield. The protein content of colored rice was significantly higher than that of the conventional rice, while the mineral elements were mainly found in colored rice seed husk.

Key words: functional colored rice, material production, yield, mineral content
