The study on the organoleptic evaluation of custard apple pulp stored up to 70 days was carried out in the Department of Agricultural Process Engineering, C. A. E. T., and M. A. U. Parbhani in the year 2005 - 2006. Statistical analysis and sensory evaluation of the data was carried out and it was observed that effect of storage of custard apple pulp at - 4 and -18°C temperature up to 70 days on scores for sensorial quality of pulp viz appearance, color, flavor, taste, texture and overall acceptability increases from 7.25 - 8.20, 7.3 - 8.0, 6.0 to 7.25, 6.0 - 7.25, 6.25 - 7.0, and 6.30 - 7.5, respectively. The application of heat facilitates molecule damage of constituents of pulp by denaturation of protein, evaporation of volatile constituents and gelatinization of starchy material. This may lead to the changes in sensorial characteristics of the pulp like increased viscosity loss of flavor and taste and change in color.

An attempt was made to determine the most effective mechanical treatments that is ringing and girdling in relation to upper and lower portion of the shoot of guava, lemon and pomegranate. The results revealed that cuttings obtained from lower end portion of ringed branch (M2) promoted significantly better growth parameters, particularly number of sprout shoots (4.0), shoot length 120 days after planting (28.00 cm), number of leaves (45.66), length and width of leaves (8.03 and 3.24 cm), leaf area index (41.24 cm2) as well as better success of rooting percentage (80%) in lemon followed by pomegranate (78%). In case of crop response, lemon significantly response to cuttings made from lower end portion of ringed branch followed by pomegranate subjected to shoot and root characteristics.

The present studies were carried out to consolidate information on anatomical features of stem, root and leaves from different vigour groups of citrus rootstock varieties. Troyer citrange (Citrus sinensis × Poncirus trifoliata), rough lemon (Citrus jambhiri), swingle citrumelo (Citrus paradisi × P. trifoliata), sweet lime (Citrus limettioides), carrizo citrange (C. sinensis × Poncirus trifoliata), sour orange (Citrus aurantium) and flying dragon (P. trifoliata) were examined to investigate relationships between their internal structure and vigour. It was found that vigorous rootstock, rough lemon (C. jambhiri) possessed lower proportions of bark (phloem) in the stems and roots as well as larger vessel elements in the xylem, when compared with least vigorous rootstocks, flying dragon (P. trifoliata). Smaller but more vessel elements were found in stem cross-sections than root cross-sections of three month’s old rootstock seedlings. The possible mechanism of vascular differentiation induced by young leaf primordia, following the original polarity and developing toward the roots is discussed.

Key words: Citrus rootstock, anatomical features, stem, root, leaves.

Tropical home-gardens are widely recognized as a repository of biodiversity of domesticated and wild plant, and animal species that need to be developed to meet livelihood needs and for purpose of their conservation. Despite being the oldest form of agroforestry, this system is still poorly studied and understood. This study investigates the pattern of indigenous and exotic flora in the home-gardens managed by urban dwellers in São Luis city, Maranhão, Brazil. Forty home-gardens were randomly selected from ten locations and studied for their species richness and diversity, floristic distribution and canopy structure. The species were categorized as exotic and indigenous to Brazil. The home-gardens were species-rich, with 186 plant species in total. Of the species recorded, 62% produced edible fruit and nut trees, 17% were food crops, 7.5% were condiments, 7.5% were of medicinal value and 6.4% were timber species. Nearly 60% of all species were indigenous. Differences in species composition determined differences in vertical canopy structure. The floristic composition and high abundance of indigenous and exotic species managed or retained in the home-gardens demonstrates high degree of biodiversity conserved by urban dwellers in São Luís.

Key words: Homegardens, canopy structure, floristic composition, São Luis.

The application of Trichoderma multiplied culture (TMC) of T. harzianum strain Th 37 @ 20 kg/ha on the stubbles at the ratoon initiation stage increased the availability of nitrogen (N), phosphorus (P) and potassium (K) by 27, 65 and 44%, respectively. Availability of some of the micronutrients viz., Cu, Fe, Mn and Zn were also enhanced, respectively by 6, 100, 79 and 66%. There was a considerable increase in organic carbon (55%) with concomitant decrease in soil pH (6%).There was significant difference in nutrient uptake between highly red rot susceptible variety (CoLk 7710) and moderately resistant variety (CoS 96268). The increase of N uptake was more in susceptible CoLk 7701 (69%) where as the uptake was only 45% in moderately resistant CoS 96268. P uptake increased by 96% in CoLk 7701 and 69% in CoS 96268. K uptake increased 128% over control of CoLk 7701 and 59% in CoS 96268. The level of protection against red rot increased up to 78% in combination with TMC + salicylic acid (SA) and 86% with metabolites + SA where as the protection was 60 and 71%, respectively with TMC and metabolites. Application of TMC + SA resulted in significant growth promotion through improvement in ratoon initiation (15%), number of tillers (8%), cane height (5%), girth (4%), number of internode (8%), length of internode (2%), single cane weight (5%) and number of millable cane (4%) which was reflected in the improvement in average yield by 23%.

The present investigation on genetic variability including mean, genotypic and phenotypic variances, coefficient of variation, heritability, and genetic advance was conducted on genetically diverse twenty three genotypes of bell pepper. Significant differences were observed among the genotypes for all the traits. On the basis of mean performance, genotypes PRC-1, SSP, Kandaghat Sel. and Ranichauri Sel-1 were outperformed for fruit yield per plant, average fruit weight, number of fruits per plant and took less number of days to 50% flowering. The phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) were high for fruit yield per plant and ascorbic acid content indicating that these traits had wide genetic variability and would respond better to selection. High heritability and high genetic advance were recorded for average fruit weight, fruit yield per plant, fruit diameter, number of lobes per fruit, days to first harvest, leaf area and ascorbic acid content indicating the role of additive gene action for the inheritance of these traits. At genotypic levels, the traits fruit length, fruit diameter and number of fruits per plant revealed significant positive correlation with fruit yield per plant. Number of fruits per plant exhibited the highest positive direct effect followed by average fruit weight, number of branches per plant, pedicel length and harvest duration at genotypic level.
