Reproductive Characters of Parthenium Weed under Different Environments
seed production and 1 000seed weight about Parthenium weed under different environments including crop land
grazing land
sparse forest and roadside were studied in this paper. The results showed that the characters above all of Parthenium weed under different environments were various. The population density ranged from(10±2)~(80±24)/m2
capitulum number ranged from(2 618±843)~(14 539±3 296)/m2
seed percentage range from (43.8±5.6)%~(82.5±2.2)%
seed production ranged from(10 308±1 036)~(60 361±14 661)/m2
1 000seed weight ranged from (0.34±0.06〖DK〗)~〖DK〗(0.46±0.01) g. To the population along the roadside
the density was the maximum while seed percentage and 1 000seed weight was the minimum. In vitro
to the population distributed in crop land and sparse forest
the density was the minimum while seed percentage and 1 000seed weight was the maximum. The invasive ability and adaptation of
Parthenium hysterophorus
to environment were discussed in this paper according to reproductive characters.
