| This experiment in changbai mountains, wild and cultivated and the dragon rhodiola for materials, mainly studies the seeds of rhodiola morphological properties, characteristics and germination of amino acid content analysis, the results showed that:(1) rhodiola pistil skin color when young for centrifugal by shallow green, red when ripe, seed maturation into deep red after become red brown.(2) rhodiola centrifugal skin for nearly triangular section, centrifugal thick wall is the outer skin skin cells, the arrangement is neat, wall is composed of cells to thick wall, 8-10 layers parenchyma cells, and has six vascular bundles; Everyone has a number of centrifugal pigskin, ranging from the ovule ovules longitudinal neatly arranged 2 inclined to radicle, in turn, the embryo.(3) rhodiola seed morphology, similar to a banana skin is light brown, dark brown, provide a bit luster, the surface has multiple strips, yea, than for longitudinal strips, some is a tall, some neat is irregular, two seeds with thicker edges.(4) rhodiola seed size disparity between the large seed is average length, for 1.650-1.855 mm, width is 0.433-0.488 mm, medium for the seeds of the average length and width 1.438 mm 138.5m-0435-for 0.447 mm, small seeds average length for 1.120-1.390 mm, width is 0.386-0.435 mm.(5) rhodiola seed soaked with water temperature increase at low temperature than in this experiment germination, the highest germination when 8 degrees.(6) inside short time of storage time rhodiola seed germination, but no significant effect of storage temperature has influence on germination and save 20-the highest seed germination rate, In the next 20°c ShiShengMiao seed preservation of survival in 20-28 degrees conditions.(7) rhodiola seeds, the most abundant amino acids, amino acid is followed by arginine, aspartic acid leucine, Sue, lysine, cysteine, at least, Human body essential amino acids rhodiola seeds and essential amino acid content, but its always about the different proportion of amino acids.
