| dc.description.abstract | A field survey was conducted to investigate the distribution of Cryptocoryne ciliata · in Larut Matang, Perak ( 4° 47 .8' N, 100° 38.0' E ). Six plots were established along the main river; Sungai Larut (Plots 1 and 2 ), and its tributaries Sungai Lang ( Plots 3 and 4 ) and Sungai Jebong ( Plots 5 and 6 ). Cryprocoryne ciliata found grew in clump along the river'bank. A regression curve was calculated based upon distance from the river mouth ( x) and plant height ( y ). The regression was y = -75.46 + 46.89x - 2.59x2. The study on life cycle and pollination ecology of C. ciliata was conducted at the palm oil plantation ( 4° 49.9' N, 100° 39.9' E ). The vegetative life cycle ( 1.7 years ) was relatively shorter compared to the sexual life cycle ( 2.3 years ). The bright brick colour and the decaying odour of the fruit attracted insects to the flowers of C. ciliata. Pest insects recorded were from the Order Onhoptera and Diptera, whereas the pollinating insects were Drosophila melanogaster (Order Diptera) and Haproncus species (Order Coleoptera). Experiments on seed germination and petiole enlongation or C. ciliaw were carried out in PlanL HouseaL Universiti Sains Malaysia. Percentage germinations were higher ( 95.0 ± 2.0%) on loamy silt soil compared to on sand ( 40.0 ± 6.1 'Yo ). Seeds fail to grow on soil watered with 20% sea water. No gennination also found in acidic (pH 3.5) water medium. The rate of petiole enlongation was higher in submerged condition ( 1.95 em/ month ) compared to those condition exposed to air ( 0.78 em/ month ). | en_US |
