Heterospory in Pteridophytes || Origin and Importance

Heterospory in Pteridophytes Pteridophytes serve as a link between bryophytes and seed plants. In Pteridophytes, heterospory was reported in the late Devonian period. They are vascular plants with roots, stems, and leaves but no flower or seed. Most of the Pteridophytes are homosporous as they produce only one kind of spore. In homospory, the sex…

Top 10 Factors Affecting Herbicide Carryover/Residue | BotanyLive

There are many factors affecting herbicide carryover or residues in soil and plants like residue itself, some biotic (microbes, plants), abiotic (soil, moisture, light), and chemical (degradation process, half-life) factors. Herbicides destroy plants (herbs) and more specifically off-type plants or weeds. After destroying weed plants or limiting their growth, herbicide residues may persist in the…
