title: [Characteristics of fructification and seed ripening of Panax stipuleanatus].
abstract: Characteristics of fructification and seed ripening of Panax stipuleanatus were studied in this paper with a view to better understand the species' biological characteristics and promote cultivation. Dynamic of fructification and types of fruits were observed in a period of 80 days. The seeds' biological characteristics were evaluated by observing embryo's vitality and changes in form in a period of 225 d. The findings and conclusions were as follows: A plant produces an average of (38.7 +/- 6.5) seeds; Seeds become fully mature 80 days after setting fruit, and fruits grow more rapidly in 0-40 days with an increase of 1 500.83% in fresh weight. Three types of fruits were found, that is mono-seed type, bi-seeds type and triple-seeds type, and the proportion is 9.53%, 58.66%, 1.81%, respectively. The seeds are (5.16-6. 52) mm in length and (3.12-4.95) mm in width. The weight of 1000 seeds is (0.648 +/- 0.014) g with a moisture content of (55.23 +/- 0.49)%. The after-ripening of embryo in Panax stipuleanatus is morphological form, embryos develop 75 days after the seeds' detaching from mother plant and become mature in 165-180 days with the ending of the process of after-ripening. The vitality of embryo reaches 70% , and the length of embryo is (3.217 +/- 0.406) mm and the width (0.872 +/- 0.165) mm. The seeds will germinate in 195 d.
