Abstract: By measuring the germination rate, germination energy, growth and seedling growth process of Lupinus micranthus seeds under different temperature and matrix conditions, the effects of temperature and matrix on the germination of L. micranthus seeds were analyzed. The results showed that, temperature had a significant effect on seed germination and seedling growth, and was the most important environmental factor for L. Micranthus seed germination and seedling growth. 15 ℃ was the most conducive to obtain a higher germination rate and 25 ℃ was the most conducive to obtain high growth. The matrix had a very significant effect on the maximum growth of L. micranthus, and had a significant effect on the initial stage and germination energy, but had no significant effect on the germination rate, end stage, germination days and average daily growth. The most comprehensive advantage of the matrix was perlite, vermiculite was the most conducive to the growth of seedlings. Temperature and matrix had obvious interaction effects on germination rate, germination period index, germination energy and maximum growth, the optimal treatment of temperature and matrix was “15 ℃+local yellow heart soil” and “15 ℃+peat”.

Key words: Lupinus micranthus seed, germination characteristics, temperature, matrix
