The effect of prepackaging (1 percent vented High Density Polyethylene (200 gauge) bag) and pretreatments (1.5 percent potassium metabisulphite (KMS) solution (T1) and 2 percent sodium chloride (NaCl) and calcium chloride (CaCl2) solution (T2) on physiological loss in weight (PLW), total soluble solids (TSS), pH, titratable acidity, firmness and colour (L a b) of star fruit, egg fruit and fig was studied during storage in ambient (R1) and refrigeration (R2) conditions (4±1 oC). The experimental results indicated that a decrease in titratable acidity, fruit firmness, increase in pH and total soluble solids (TSS) content under both pretreatments and storage conditions. The pretreatment (T2) however extended star fruit and egg fruit marketable life with lowest PLW (8.04% and 4.52%) and physico-chemical constituents up till the 22th and 16th days at ambient temperature and more than 25th (7.47%) and 20th (3.40%) days under refrigeration condition. This might be due to the pretreatment with 2 percent NaCl and CaCl2 solution which delayed fruits ripening periods during storage. Whereas the fig pretreated with T1 had better shelf life (4 days) with respect to physical properties during storage at refrigeration temperature than control. The results of the study indicated that pretreatments T2 and T1 found to be better for improving the shelf life of star fruit (25 days), egg fruit (20 days) and fig (4 days) under room and refrigerated storage.Keywords

Fusarium yellows/wilt caused by Fusarium oxysporum f.sp.phaseoli are one of the serious diseases in French bean in Thandikudi and Kodaikanal hills of Dindugal district was found to prevalent in all French beans growing areas under survey with maximum of 71.25 per cent incidence and 65.88 per cent disease severity at Thandikudi village of Dindugal district in Tamil Nadu. The pathogenicity test was conducted by artificial inoculation of test fungus into the young two leaf stage of French bean and the typical symptom were produced after twelve days after inoculation. Among the different solid and liquid media tested oat meal agar potato dextrose agar medium supported growth of the casual fungus. Fungus could grow well at a pH 4.0 and 5.0, respectively. This pathogenic fungus grew maximum when basal medium was supplemented with lactose and dextrose as carbon sources showed maximum growth and with potassium nitrate and sodium nitrate as nitrogen sources.Keywords

The present research work was undertaken to identify the genetically divergent genotypes for higher yield and desirable quality traits under shade net in tropical climatic condition. The study consisted of eighteen genotypes collected from different places were raised, evaluated and studied for mean performance for yield and yield contributing traits and for quality traits. Based on per se performance of genotypes, the genotype Solan Red Round was adjusted as the best for tropical condition, since it had recorded superior performance for twelve characters viz., number of branches per plant (21.1), number of fruits per cluster (5.13), single fruit weight (10.57g), pericarp thickness (2.24mm), fruit yield per plant (2.94kg), estimated fruit yield per hectare (73.42t), total chlorophyll content (4.08mg/g), leaf area index (1.91), dry matter production (2.5t/ha), titratable acidity (0.42%), total soluble solids (6.030 Brix) and lycopene (1.96mg/100g). It was followed by Kamanoor Local, K C Patti Local, Aadalur Local and Kodalangadu Local under shade net condition. The highest plant height (5.18m) and number of clusters per plant (96.57) was recorded in Aranuttrumalai Local and Thandikudi Local, respectively.

The present investigation was carried out at Department of Horticulture, Agricultural College and Research Institute, Tamil Nadu Agricultural University, Madurai during Kharif 2015 with 32 pumpkin (Cucurbita moschata Duch. ex. Poir) collected from different parts of Tamil Nadu to identify small fruited high quality genotypes. The genotypes CM-9, CM 3, CM 14 (3.40) recorded more number of primary branches, the highest vine length was recorded in CM18, CM10, CM15 (10.66, 10.50, 9.67m) genotypes. The higher petioles were recorded in CM21, CM18, CM4 (26.63, 24.77, 24.50cm). The higher leaf length was recorded in CM5, CM11, CM1, CM9, CM8, CM23, CM2, CM31 (14.03 to 14.93cm) genotypes. The leaf breadth was highest in CM15, (22.00), the higher inter nodal length in CM17, (13.53cm) were recorded. The first male flower in seventh node was observed in CM23, CM1, CM32, CM30, CM4, the first female flower appeared early in CM12, CM26, (20 and 21st node), the days taken for male flowering was ranged from 47.20 to 54.20 days and for flowering ranged from 51.73 to 63.27 days. The early female flowering was recorded in CM29, CM20 and CM17. The lowest sex ratio was recorded in CM30 (13.58). The days taken for fruit maturity less in CM29, CM28 and CM5 (83.47, 87.27 and 87.53 days). The genotypes CM29, CM28 recorded higher number of fruits per plant (4.40 and 3.13) and less fruit diameter (17.80 and 18.33cm), fruit length (44.40 and 49.73 cm), fruit weight (0.97 and 1.11kg), 100 seed weight (10 and 15g). The highest yield per plant was recorded in CM12, CM23, CM3 (9.48, 8.54 and 7.60kg). The highest TSS content (100Brix) in CM13, acidity (0.78) in CM27, ascorbic acid (10mg) in CM23, moisture content (99%) in CM30, CM31, beta carotene content in CM29, and CM28 (0.99 and 0.89 mg). The CM29 and CM28 genotypes were identified as small fruited type among the genotypes studied.
