The effects of zinc (Zn) and C14-indoleacetic acid (IAA) on leaf senescence ın Helıanthus annuus L.

Sequential leaf senescence is defined as a kind of programmed death events which is an important process in growth of plant. This study aimed to explore the sequential leaf senescence rate due to indoleacetic acid and lack of zinc (-Zn). Therefore, the effect of zinc and indole-3-acetic acid on senescence which occurs in Helianthus annuus (sunflower) cotyledons was analyzed. It was found that in cotyledons of seedlings...

Interactive effects of virus and Rhizobium inocula on nodulation, growth and yield of cowpea

The effect of separately inoculating cowpea cultivars, ‘Ife brown” (IF) and “Owode” (OW) with Cowpea aphid-borne mosaic virus (CABMV), Cowpea yellow mosaic virus (CYMV) and Rhizobium IRc 284(RH-284) on nodulation was investigated. Also, the effect of inoculating the cowpea cultivars with RH-284 on the severity of infection caused by the viruses was studied. The interactive effects of inoculating...
