Date of Publication
Examined the effect of a vesicular-arbuscular mycorrhizal (VAM) fugus Glomus pallidum Hall on the phosphatase activity and cytokinin concentration in cowpea [Vigna unguiculata (L.) Walp] roots at successive stages of plant growth. Both acid and alkaline phosphatase activity were significantly (P=0.05) higher in mycorrhizal than in non-mycorrhizal roots 30 days after inoculation. Similarly, the cytokinin content was significantly increased in mycorrhizal roots compared to non-mycorrhizal roots. Study suggests that these biochemical changes may improve the growth of mycorrhizal cowpea plants.....
