The selection methods applied in soybean breeding are those used in improving autogamous plant species.
The stamens and pistil of d. versipelis mature before the flowers open, which shows that dysosma versipelis may be autogamous. d. versipelis produce few fruits. ovaries of d. versipelis seldom develop in nature, but will develop after being pollinated with pollen of another plant
The cross-pollinating representatives are totally different.
They were maintained by normal self-pollination.
Changes in concentrations of boron ( b ) and magnesium ( mg ) in the ovary ( fruitlet ), rind and pulp of fruit were investigated throughout fruit development of parthenocarpic kamei satsuma mandarin ( citrus unshiu marc. ) and self - pollinated egan 1 tangerine ( c. reticulata blanco ). the results showed as follows : 1 ) b concentrations in the ovary of kamei were at high levels before flowering and at full bloom, and decreased after flowering, whereas that of egan 1 was relatively low at full bloom, thereafter significantly increased. no significant differences were observed in mg changes in the ovary ( fruitlet ) between the two cultivars, which presented decreasing trends after flowering. 2 ) minor changes of b concentrations in the rind of the two cultivars were detected, remarkable changes were found for b in the pulp, which came to the peak values during the stage of fruit enlargement. mg concentrations were relatively high in the rind and pulp of the two cultivars during early fruit development, and presented obviously declining trends during the middle and late stage of fruit development
以單性結實的龜井溫州蜜柑和自花授粉結實的鄂柑1號橘為試材，對整個果實發育期的子房（幼果） 、果皮和果肉的硼鎂含量變化進行了測定.結果表明: 1 ）龜井花前至花期子房硼含量就已較高，花後下降;而鄂柑1號花期子房硼含量相對較低，花後有一顯著上升;兩品種子房（幼果）鎂含量變化無明顯差異，花后均趨下降. 2 ）兩品種果皮硼含量變幅較小，而果肉硼含量變幅相對較大，且均在果實膨大期出現明顯的上升高峰;兩品種果皮和果肉鎂含量在果實發育前期均相對較高，在果實發育的中後期則趨明顯下降
