Abstract:
Flower structure and flowering phenology were investigated by position observation,bagging test of Xanthoceras sorbifolia Bunge in the Yinchuan of Ningxia.The florescence,daily development,premature drop were observed.The results indicated that flowering time of Xanthoceras sorbifolia Bunge was between the last part of April to the earlier part of May,anthesis of individual lasted 5-7 days.Flowering time,however,was shortened to 1-2 days in high temperature and prolonged to 1-2 days in low temperature.Monoecism plant and the two kinds of flowers (fertile and infertile floret) had similar structures of floral organ during the early stage of sex differentiation.They both had stamen and pistil,anthers of fertile were not normal outward appearance,anthers of infertile were normal outward and degradation in pistil.The inflorescence of Xanthoceras sorbifolia Bunge existed flower-drop and fruit-drop seriously.Naturally setting was low,only 1.48%.
