Arrowleaf sida (Sida rhombifolia) and prickly sida (Sida spinosa): germination and emergence
Weed Research, 1992Summary: Résumé: ZusammenfassungMaximum arrowleaf sida (Sida rhombifolia L.) germination occurred at 35°C, whereas prickly sida (Sida spinosa L.) germinated to the same extent at 35 or 40°C. Arrowleaf sida germinated better than prickly sida at 20 and 25°C, but did not germinate at 40°C. Less than 50% of seed from both species were viable at 45°C after
