Abstract

Dolichomitriopsis diversiformis(Lembophyllaceae)is an endemic species of east Asia. Its distribution area inChina isbecoming smallerand smallerforenvironmental stress.Its reproductionmay be one of the reasons to be endangered. The seasonal dynamics of biomass allocation to reproductive organs and to vegetative organs of Dolichomitriopsis diversiformis by weighting were studied in its each phenological periods in Mount Fanjing of Guizhou Province. The results showed that reproductive organs did not grow during nutrient growth and dormancy,so biomass allocation did notoccurin these two periods.In the reproductive growth period,biomass allocation to the reproductive organs was 0.74%. In the young reproductive period, biomass allocation to the perichaetium was 0.57% and to the young sporophyte, 2.36%. During the mature reproductive period, biomass allocation to reproductive organswas 4.77%, and in the old reproductive period itwas 3.06%. This research is the basic work to study the species reproductive ecology.[Ch, 1 fig. 2 tab. 9 ref.]
