Photocontrol of Hook Opening in Cuscuta gronovii Willd.
Hook opening in seedlings of Cuscuta gronovii Willd. occurred only after prolonged exposures to blue, red, or far red light. Prolonged far red exposure was less effective than prolonged exposure to red or blue light. Brief far red irradiation inhibited the inductive effect of red light. The far red inhibition was in turn reversed by brief red irradiation. These effects suggest the involvement o...
متن کاملVerbesina alternifolia Tolerance to the Holoparasite Cuscuta gronovii and the Impact of Drought.
Holoparasites are nonphotosynthetic plants that acquire all resources from hosts. The holoparasite Cuscuta gronovii is native to much of the US with a broad host range including Verbesina alternifolia, an understory perennial. Both species grow in moderate to moist soils and occur in habitats that may experience prolonged or episodic drought. We applied the Wise-Abrahamson Limiting Resource Mod...

متن کاملIdentification of Tinospora cordifolia (Willd.) Miers ex Hook F & Thomas using RAPD markers.
Identified germplasm is an important component for efficient and effective management of plant genetic resources. Traditionally, plant identification has relied on morphological characters like growth habit, floral morphology like flower colour and other characteristics of the plant. Studies were undertaken for identification and genetic variation within 15 clones of Tinospora cordifolia throug...
