Abstract

Interaction effects of leaf area and IBA treatment on drifts in endogenous carbohydrates were studied in relation to rooting of juvenile cuttings of teak (Tectona granis Linn.f.). It was observe that the per cent rooting, sprouting, number of leaves, roots per cutting and shoot height and root length were significantly affected while number of shoot per cutting showed insignificantly variation due to the treatment of IBA 200mg and presence of different leaf area on the cuttings. The interaction effect between leaf area and IBA treatment showed significant effects only on number of leaves, roots per cutting and shoot height and root lengths. The rooting zone of the cuttings of different leaf area, treated and control were also harvested after 0, 10, 20 and 30 days to assess the total sugar content fluctuation during adventitious root formation. All IBA treated cuttings that was belonging to different leaf area showed increased total soluble sugar content. However, in both the cuttings (treated and control) the maximum decline in total soluble sugar was observed up to 20 days with subsequently small reduction to day 30. Total soluble sugar was reduced maximum in rooting zone of the cuttings after 30 days harvestation by the IBA 200-mg treatment that have 25 cm2 leaf area. It is concluded that leaf area and IBA treatment affected rooting response of teak cuttings and cuttings and total soluble sugar fluctuation in rooting zone of cuttings during adventitious root formation.
