OPTIMIZATION OF QUALITY IN EXPORTED Polyscias balfouriana “MARGINATA” BY USING DIFFERENT SHADE LEVELS Gunadasa, H.K.S.G; Dissanayake, P.K Foliage plant industry in Sri Lanka often has to face difficulties due to problems associated with the qualities of the final product of plant especially, pale green colour leaves and poor quality shoots, which are not accept by the buyers in export market. An investigation was carried out to develop the green colour and other qualities of Polyscias balfouriana “Marginata” (PBM) using different shade levels within 10 weeks. Canes, 10 cm long were used as planting materials and planted in coir beds under, 55, 60, 65, 70, 75, 80, 85, 90 and 95% shade levels. Other qualities evaluated for PBM were shoot length, leaf area, number of leaves per shoot. It was evident that the preferable forest green colour was achieved significantly (p = 0.001) at the highest shade levels of 85 and 90%. The leaf area of 14 cm2 and, sprout of 7 cm to 7.5 cm length also achieved at highest shade levels of 85% and 90%. Percentage of canes with 3 or more than 3 leaves per shoot was significantly higher than that of canes with less than 3 leaves at shade levels higher than the control. The higher percentage of acceptable canes with 3 or more than 3 leaves was found in shade level of 80%, 85% and 90 %. With these findings it can be concluded that the use of high shade levels such as 85% and 90% at foliage nurseries are favorable to obtain quality PBM plant for export market.

EFFECT OF SEDATIVE TECHNIQUES ON PHYSIOLOGICAL PARAMETERS OF CALVES AT (MINOR SURGICAL PROCEDURES) L OR HERNIORRAPHY Sarker, N.C; Hashim, M.A; Ray, B.P The effect of sedatives and analgesics on heart rate, respiration rate and rectal temperature were observed. Heart rate and respiration rate significantly (p<0.01) decreased during sedation with xylazine hydrochloride plus 2% lignocaine hydrochloride or 0.5% bupivacaine hydrochloride. A significantly decreased (p<0.01) heart rate and respiration rate also found during sedation with diazepam plus 2% lignocaine hydrochloride or 0.5%bupivacaine hydrochloride. Two percent lignocaine hydrochloride showed short onset, rapid spreading and no side effect. Duration of analgesia was longer with 0.5 % bupivacaine hydrochloride (55.88±1.58 min in Group B and 48±11.25 min in Group D) compared to 2% lignocaine hydrochloride (39.60±5.77 min in Group A and 43.6±5.81 min in Group C). Xylazine hydrochloride showed short onset and long duration of sedation compared to diazepam. Therefore, herniorraphy, xylazine hydrochloride can be used as a better sedative while 0.5 % bupivacaine hydrochloride can be used as a local analgesic for longer duration of action.

CORRELATION ANALYSIS IN DIFFERENT PLANTING DATES OF RAPESEED VARIETIES Rameeh, V The present study was aimed at finding out the planting dates effects on yield associated traits and also determining the variations of correlations among the traits in different planting dates of rapeseed genotypes. Significant planting dates and genotypes effects for phenological traits, yield components, seed yield and oil percentage revealed significant differences of planting dates and genotypes for these traits. Plant height had positive effect on pods per plant by increasing number of branches in each plant and length of main raceme. 1000-seed weight had significant positive correlation with seed yield, so any changes for this trait had considerable effect on seed yield. The variation of correlation between duration of flowering and pods per plant was less than the correlation of duration of flowering to other traits in different planting dates, so it can be used as selection breeding criterion.

CONSUMER PERCEPTIONS ON QUALITY ATTRIBUTES OF LIQUID FOOD PRODUCTS: AN EMPIRICAL ANALYSIS BASED ON URBAN HOUSEHOLDS

CONSUMER PERCEPTIONS ON QUALITY ATTRIBUTES OF LIQUID FOOD PRODUCTS: AN EMPIRICAL ANALYSIS BASED ON URBAN HOUSEHOLDS Silva, W. G. M; Udugama, J. M. M; Jayasinghe-Mudalige, U. K This study examined empirically the urban consumer perceptions on key food quality attributes, including price, food safety, labeling and packaging for four liquid food products, namely bottled water, pasteurized milk, ready-to-drink fruit juices and carbonated drinks. Given the multidimensional nature of issue, the Perceptual Mapping Method explained in the Multidimensional Scaling multivariate data analysis techniques was employed to estimate and map the variations in consumers’ similarity judgments on the quality attributes. A structured questionnaire was administrated with 300 households in the urban areas in the Colombo district to collect data from May to July 2011. The outcome of analysis revealed that, irrespective of the product, price plays the most significant role on consumer decision making process followed by food safety. Nevertheless, consumers were judged differently on these quality attributes as they decide on purchasing different product combinations and this behavior is correlated with the socio-economic status of a consumer. The results imply that manufacturers of these products shall pay attention to the food quality attributes in concern in their attempt to cater into their client-base and penetrate into new food markets
