The determination of the time between
anthesis and harvest was performed throughout the year, with colored ribbons, 28 naturally pollinated flowers (open pollination) and 26 manually pollinated flowers and the number of days from
anthesis to harvest was observed, which in this species occurs with the natural detachment of the fruit from the plant.
At pre-anthesis the flora buds were bagged and, at
anthesis, the nectar secretion volume was measured with microcapillary graduated (precision [+ or -] 0.2 ul) and then discarded.
Grain yield was most highly correlated with shoot biomass at
anthesis (r=0.83, P<0.001), P uptake at stem elongation (r=0.83, P< 0.001), shoot P concentration at stem elongation (r=0.79, P<.001), P uptake at
anthesis (r-0.78, P<0.001) and shoot biomass at stem elongation (r=0.78, P<0.001).
Days to spike emergence and
anthesis were observed when 50% of the plants within a pot had spike and protrusion of anthers respectively.
A.; Martre, P Simulation of environmental and genotypic variations of final leaf number and
anthesis date for wheat.
Significant differences in the viability of maize pollen grains were detected among cultivars, days of
anthesis, and times of day (Table 1).
The GLAI in both HPD and LPD rapidly decreased after peak
anthesis, and this value was lower in HPD than in LPD after 14 DAPA.

anthesis, ear height.
The higher grain yield in kg/ha was produced by PBGST-03, PBGST-04, Bhittai and Sarsabz in water stress imposed at
anthesis. Thus, these cultivars sustained the water stress by showing drought tolerance against other cultivars under evaluation.
Approximately ten flowers from five plants of each sex were observed daily for four days each year to determine the time and duration of
anthesis.
