The effects of photoperiod and light intensity on flowering in Mat Rush cv. Gangshan 3 were studied. The results showed that
treatments with longer day length stimulated flowering significantly and increased stem flowering percentage (SFP). Plants
treated with low light intensity at early stage had substantially reduced florets per cyme, SFP, tillers per plant and stem
length. At middle and late stage, low light intensity significantly reduced SFP. The principal climatic factors affecting
SFP were as follows: mean temperatures (MT) of the third ten-day period (TDP) in December and of the second TDP in February,
actual sunlight hours (SH) of the third TDP in February and precipitation of the third TDP in March. A nonlinear simulation
model for SFP was established with experimental results and corresponding climatic data (see Eq. (2)).
Simulation by the above equation yielded values the same as those observed from 1992 to 2000, indicating its accuracy in describing
the relationship between flowering and light and temperature conditions. The interaction between vernalization and SH is also
discussed in this paper.
