为了解不同种皮色地方稻种的总黄酮含量与其种子萌发品质的相关性,测定了17份云南地方稻种谷粒、糙米和谷壳的总黄酮含量,以及谷粒和糙米的发芽势、发芽率、发芽指数和活力指数4项萌发指标。结果表明,红皮和紫皮谷粒及糙米的总黄酮含量显著、极显著高于白皮,而谷壳的总黄酮含量则无明显差异。红皮谷粒的4项萌发指标均高于紫皮和白皮,但仅红皮与白皮谷粒之间的发芽势差异达到极显著水平;红皮糙米的4项萌发指标极显著地高于紫米和白米,且除发芽指数外,紫米的其他3项萌发指标显著或极显著地高于白米,表明有色种皮谷粒、糙米的总黄酮含量较高,其萌发指标也相应较高。相关分析表明,谷粒的总黄酮含量与4项萌发指标之间没有明显的相关性,但糙米的总黄酮含量则与4项萌发指标呈显著正相关;谷壳的黄酮含量与种子萌发无关,而糙米的黄酮含量则显著地影响种子的萌发特性。 In order to understand the correlation between the total flavonoid content and the seed germination quality of different seed coat color local rice varieties, the total flavonoid content of 17 Yunnan local rice varieties, brown rice and chaff, as well as the germination potential of grain and brown rice, Germination rate, germination index and vitality index 4 germination indicators. The results showed that the contents of total flavonoids in red and purple skin and brown rice were significantly higher than those in white skin, while the content of total flavonoids in chaff did not change significantly. The four germination indexes of red-grained grains were higher than purple ones and white ones, but only the differences of germination potential between red-skin and white ones were extremely significant. The four germination indexes of red-brown rice were extremely high In purple and white rice, except for germination index, the other three germination indexes of purple rice were significantly or extremely significantly higher than that of white rice, indicating that the content of total flavonoids in colored seed-coated cereals and brown rice was higher and their germination indexes were also correspondingly high. Correlation analysis showed that there was no significant correlation between the total flavonoid content of the grains and the four germination indexes, but the total flavonoids content of the brown rice showed a significant positive correlation with the four germination indexes. The flavone content of the chaff did not correlate with the seed germination, The brown rice flavonoids significantly affect the seed germination characteristics.
