    • Abstract


      Plants ofN. indicum andT. peruviana grew taller and produced more leaves underld than undernd condition. WhileT. peruviana plants were taller and had more leaves undernd than undersd, those ofN. indicum did not differ under the two photoperiods. In both caseslds delayed the onset of bud dormancy but hastened the initiation of floral buds. While inT. peruviana floral buds were not formed undersd condition, inN. indicum floral buds were formed but they did not develop into flowers. While inN. indicum more flowers were produced underld than undernd condition, inT. peruviana the number produced was higher undernd than underld condition.
