Comparison of germination rate and root seed establishment for Ipomoea purpurea and Ipomoea x leucantha (Convolvulaceae)

Abstract

Germination and establishment of the root seed of two weeds (Ipomoca purpurea and Ipomoea x leucantha) were compared. During germination fresh weight, dry weight, length stem height vegetative form, length and width of the first three leaves and petiole were determined. The results show that for the parameters studied Ipomoea purpurea has the highest values, the differences being statistically significant. The results show that germination and postgermination of the seed and establishment of the plant of Ipomoca purpurea is more efficient. Ipomoea purpurea seeds have a greater mass, longer root, the vegetative form but outpost and establishes a leaf area in shorter time.
