0 a plant that produces flowers and has two cotyledons (= leaf parts inside the seed) -- 双子叶植物（种子有两片子叶的植物）
Transects from the crabless zone contained twice the density and diversity of dicotyledons, and three times the seedling density, than transects from the crab zone.
During the spring period no one host appeared to be preferred, with both mono- and dicotyledons supporting populations.
To examine whether larval migration was as efficient on heather as on a monocotyledon or on a structurally simple dicotyledon we undertook a second experiment.
The diversity of dicotyledons was also relatively low when compared to the crabless zone with only 46 species identified representing 38 genera and 25 families.
A certain parallelism can be traced in the changes of seed properties in plants of higher taxa, such as angiosperms and gymnosperms, or monocotyledons and dicotyledons.
While the number o f species diminished following crop residue application, i t increased strongly following the application of fertilizer that enhanced the seed bank of dicotyledons and largeseeded annuals.
It is easy to germinate, having two-lobed dicotyledons.
It is secreted at wounded site of dicotyledons.
