Virus diseases of cacao in West Africa. IV. Effect of virus infection on growth and water content of cacao seedlings



Virus diseases of cacao in West Africa. IV. Effect of virus infection on growth and water content of cacao seedlings



Ann Appl Biol 36(4): 440-447



Apparently healthy cacao seedlings were compared with those infected before planting with swollen shoot viruses. Infected plants were lower in dry wt., leaf area, relative growth rate, and net assimilation rate; a smaller proportion of the dry matter was in the leaves and lateral roots, a larger proportion in stems and tap roots. Infection caused extensive necrosis of the lateral roots, and reduced the rate of depletion of reserves in the cotyledons and the water content of the plant. Many of these effects were [center dot] apparent within a month of infection and planting.
