DETERMINATION OF MATURITY INDICES OF TISSUE CULTURED BANANAS (MUSA SPP.) 'WILLIAMS' AND 'GRANDE NAINE'
Growth patterns of plant crop of banana (Musa spp.) cultivars Grande Naine and Williams (AAA genome), grown in Maragwa, Central Kenya in 2006 and 2007, were determined to establish the best maturity indices to determine harvest time. The banana plants were randomly selected from an already existing orchard where the farmer followed the recommended agronomic practices. The banana bunches were allowed to grow until half, three quarter and full maturity. Data were collected on growth parameters and postharvest quality of bunches. Bunch age and finger diameter were highly positively correlated (r = 0.881 and 0.939 for Grande Naine and Williams, respectively). Finger diameter was correlated positively with pulp to peel ratio and total soluble solids (r = 0.941 and 0.997 for Grande Naine and Williams, respectively). In Williams, finger diameter was positively correlated to pulp to peel ratio (r = 0.949) and total soluble solids (r = 0.991). Fruit growth curves for both cultivars followed the pattern of bananas grown in the tropics. The best maturity indices for determining the harvest time of Grande Naine and Williams may be a combination of bunch age and grade, as these correlate very well with postharvest characteristics such as pulp to peel ratio and total soluble solids.
