Ten tomato commercial and productive single cross hybrids extensively grown in Northern Transitional Zone of Karnataka were planted in the field at UAS, Dharwad following RBD design with three replications. A 10 x 10 diallel set was generated by crossing these single cross hybrids in all possible combinations (excluding reciprocals) and 45 double cross hybrids were planted during February, 2007...

abstract strawberry is one of the most important fruit crops in the world. in this study, effect of different plant densities were studied on yield and fruit quality of strawberry 'selva' in greenhouse and laboratories of university college of agriculture and natural resources during 2002-2003. uniform stolens of strawberry were planted in holes of plastic column according to factorial in compl...

Uptake of NO(3) (-) by nonnodulated soybean plants (Glycine max L. Merr. cv Ransom) growing in flowing hydroponic culture at 22 and 14 degrees C root temperatures was measured daily during a 31-day growth period. Ion chromatography was used to determine removal of NO(3) (-) from solution during each 24-hour period. At both root-zone temperatures, rate of NO(3) (-) uptake per plant oscillated wi...

Calophyllum brasiliense (Clusiaceae/Guttiferae) is a native Brazilian medicinal plant traditionally used against several diseases, including infectious pathologies. Crude methanolic extracts (CME) and two fractions, denoted non-polar (soluble in chloroform) and polar (nonsoluble in chloroform), were prepared from different parts of the plant (roots, stems, leaves, flowers and fruits) and studie...

A mutant plant of Flaveria linearis Lag. expresses reversed O(2) response of photosynthesis (i.e. its apparent photosynthesis is stimulated at atmospheric O(2) levels). The objectives of this study were to determine the genetic inheritance of this trait and to investigate the biochemical mechanism for its expression. The mutant plant was crossed reciprocally with a plant of the closely related ...

The effects of pre-sowing magnetic treatments on the growth and yield of tomatoes (cv. Vyta), cultivated late in the season, were studied under field conditions. Tomato seeds were exposed either to a 120 mT dynamic magnetic field (induced by an experimental electromagnet) for 10 min or to a 80 mT field for 5 min. Non-treated seeds were used as controls. Plants were grown in experimental plots (...

BACKGROUND The DefH9-iaaM gene fusion which is expressed specifically in placenta/ovules and promotes auxin-synthesis confers parthenocarpic fruit development to eggplant, tomato and tobacco. Transgenic DefH9-iaaM eggplants and tomatoes show increased fruit production due mainly to an improved fruit set. However, the weight of the fruits is also frequently increased. RESULTS DefH9-iaaM strawb...

In the open-pit mining, one of the first decisions that must be made in production planning stage, after completing the design of final pit limits, is determining of the processing plant cut-off grade. Since this grade has an essential effect on operations, choosing the optimum cut-off grade is of considerable importance. Different goals may be used for determining optimum cut-off grade. One of...

BACKGROUND Flowering synchrony and floral sex ratio have the potential to influence the mating opportunities and reproductive success through female function. Here, we examine the variances in synchronous display of female and male function, ratio of male to female flowers per day and subsequently reproductive output in small populations of two monoecious plants, Sagittaria trifolia and Sagitta...
