A study was undertaken to analyses the heritability, correlation and path co-efficient for growth and fruit characters in twenty ber (Ziziphus mauritiana Lam) genotypes grown at Fruit Research Farm under Horticulture Research Centre, BARI during January to June 2006. The highest range of variation was recorded in fruit weight (6.63-44.72 g), followed by yield per plant (14.88 64.99 kg), stone w...

In implementing the integrated pest management mango (Mangifera indica L.) program using weaver ants (Oecophylla smaragdina F.) as a major component in the Northern Territory of Australia, we received a number of questions from farmers and extension officers asking whether weaver ant marks reduce internal fruit quality and induce fruit rot, which is economically important. However, this issue h...

Auxin is known to regulate cell division and cell elongation, thus controlling plant growth and development. Part of the auxin signaling pathway depends on the fine-tuned degradation of the auxin/indole acetic acid (Aux/IAA) transcriptional repressors. Recent evidence indicates that Aux/IAA proteins play a role in fruit development in tomato (Solanum lycopersicum Mill.), a model species for fle...

the objective of the study was to evaluate the cytotoxic effects of aqueous extract of cucumis melo fruit on human prostate cancer cell line (pc-3) using mtt and neutral red assays. the crude aqueous extract of c. melo was prepared by cold maceration method, filtered, concentrated and tested on pc-3 cell line. dose-dependent cytotoxic activities were exhibited on human prostate carcinoma pc-3 c...

For production of high quality grape berries, the whole cluster should ripen at one time. The lack of uniform ripening within a cluster is termed "uneven ripening," and is characterized by the presence of green berries in an otherwise mature ripe cluster. Uneven ripening of 'Concord' is a major problem in the South, often prohibiting production. Northwest Arkansas is the southern boundary for c...

A machine vision system for estimating number of citrus fruit drop was developed in this study. The objectives of this study were to design rugged hardware, to develop an image processing algorithm for accurate estimation of fruit count and to conduct field experiments. Image acquisition hardware was developed to be used in a commercial citrus grove specifically for unfavorable imaging conditio...

Quarantine inspectors search for fruit fly infestations in incoming shipments by visual inspection and by dissecting or cutting a sample of fruit in each shipment. The reliability of the latter procedure for detecting fruit fly larvae is questionable and, therefore, a test was conducted to determine its effectiveness. Infested grapefruit, mangoes, guavas, and carambolas were cut open to determi...

Flowering is a critical step in fructification. No flowers mean no fruit, and when flower number is low crop load may be limited by the number of flowers formed. In most cases, however, citrus trees form a number of flowers exceedingly higher than the final number of fruits harvested, which usually is a very low percentage of the initial flower number. As in other species which form a large amo...

An increasing world population and the competitive nature of the stone fruit market, particularly nectarines [(Prunus persica var. nectarine)], demand the selection of fruit with high quality attributes, flavor, and a wide range of maturity. Information on this subject is limited at the present time. In search of superior nectarines, a trial was conducted to study growing degree days (GDD), ful...

The hype about fruit and vegetable consumption persists as both international and national reports continue to highlight the importance of including adequate amounts of these plant foods in our daily diets. During the past decades a large number of studies have investigated the relationship between fruit and vegetable intake, disease prevention and health promotion, and scientific evidence link...
