This paper gives a systematic study of Eremurus altaicus in terms of flowering characteristics, pollinating features, style movement pattern, stigma receptivity and mating system. The result showed that it was protandrous and that the stigma had no receptivity until the end of pollen dispersal. Its style showed a regular movement pattern during the flowering phase. The style was upright, very close to anthers at first; then it quickly curved down 90° from the base just before the dehiscing of anthers, but went back to the former upright state after pollen dispersal of all 6 anthers. From the blossoming to the end of pollen dispersal, the stigma was smooth and dry, and had no receptivity to pollens until the style went back to the upright state with papillae, and mucus appeared. The curving down movement of the style significantly widened the relative distance between the stigma and the dehiscing anthers. Therefore, protandry and style movement are double safeguard mechanisms for avoiding selfing and promoting outcrossing in Eremurus altaicus, which has important significance in its reproduction and evolution potential.Keywords

Our previous study found that stomata in the leaves of Glycyrrhiza uralensis (licorice) could secrete salt crystals. In theory, secretion of salt should affect the normal functioning of stomata, thereby affecting the growth and development of G. uralensis; however, its population grows well. We suspect that there may be a trade-off between stomatal salt secretion and gas exchange from the leaves at different positions. Therefore, we compared stomatal salt secretion capacity, chlorophyll content, anatomical structure, net photosynthetic rate and stomatal conductance from the leaves at different positions of licorice. The stomata of lower leaves exhibited strongest salt secretion capacity, whereas the stomata of upper leaves did not secrete any salt. Additionally, the upper and middle leaves had significantly higher chlorophyll content than the lower leaves. The arrangement of mesophyll cells in the upper leaves was densest, and that in the lower leaves was least dense. The net photosynthetic rate and stomatal conductance in the upper leaves were highest, and those in the lower leaves were lowest. We conclude that the stomata of upper leaves are mainly used for gas exchange. In contrast, stomata of lower leaves, showing weak photosynthesis, are responsible for secreting excessive salt to maintain the inner ion balance and ensure normal metabolism in G. uralensis.Keywords
