Effects of Flooding on Growth, Yield and Aerenchyma Development in Adventitious Roots in Four Cultivars of Kenaf (Hibiscus cannabinus L.)

Abstract:
A pot experiment was performed to examine the effects of flooding on growth, yield and aerenchyma development in adventitious roots of four kenaf (Hibiscus cannabinus L.) cultivars. Three flooding treatments consisting of early season flooding (30 days after planting), mid-season flooding (60 days after planting) and late season flooding (90 days after planting), as well as non-flooding control were used in the present study. The results show that soil flooding significantly increased plant height by 108 and 107% over control in early flooding and mid-flooding, respectively. Early flooding significant decreased the number of leaves and leaf area of whole plant and core dry weights by 15, 19 and 20% over non-flooding control, respectively. Soil flooding did not show any significant effect on plant height and number of leaf among cultivars, but did for leaf area, leaf dry weight and core dry weight. Early season and mid-season flooding significant decreased root dry weight in soil by 71 and 49% over non-flooded control, respectively. No adventitious roots developed in non-flooded control. Adventitious roots located in water above soil surface had dry weight of 18, 11 and 6 g plant-1 in early season, mid season and late season flooding, respectively. No significant difference in root dry weight located in soil and root dry weight located in water above soil surface were observed among cultivars. Aerenchyma formed in adventitious roots when the plant was subjected to flooding and was more developed in roots located in water above the soil surface as compared to roots located in soil. All the cultivars formed aerenchyma in their adventitious roots with variation among cultivars. Soil flooding significantly decreased fiber yield by 13% in non-flooded control in early season flooding treatments. However, mid-season and late season flooding did not show any significant difference on fiber yield in comparison with control. The cultivars was not significantly difference on fiber yield in the present experiment.
