Experiment on evaluation of mango genotypes under high density planting system was conducted in six varieties the same age group (5 years). The observation tree characters indicated that trunk circumference ranged from 20.51 cm (Prior) to 31.29 (Chandrakaran) and crown diameter 2.39 m (Ratna) 3.09 (Vellaikolumban). qualitative data morphological viz., tree, leaf, inflorescence, fruit, stone see...

introduction roselle (hibiscus sabdariffa l.) as a medicinal plant belongs to the malvacea family. their active ingredient increases under water stress. humic acid bacteria derived from humus and other natural resources have hormonal effects and can improve nutrient absorption to enhance performance especially under stress conditions . materials and methods this experiment was conducted in the ...

As a result of a taxonomic and phylogenetic revision of Astragalus section Hymenostegis we identified a new species of Astragalus from northwestern Iran, namely A. remotispicatus spec. nov., which is described and illustrated here. It is morphologically similar to A. karl-heinzii in possessing a lax inflorescence. Phylogenetic inference of the nuclear ribosomal DNA internal transcribed spacer (...

Plants undergo a series of profound developmental changes throughout their lifetimes in response to both external environmental factors and internal intrinsic ones. When these changes are abrupt and dramatic, the process is referred to as phase change. Recently, several genes have been discovered that play a role in these developmental transitions. Their sequence and expression patterns shed ne...

To understand the constraints on biological diversity, we analyzed how selection and development interact to control the evolution of inflorescences, the branching structures that bear flowers. We show that a single developmental model accounts for the restricted range of inflorescence types observed in nature and that this model is supported by molecular genetic studies. The model predicts ass...

Two Asteraceae species, Clibadium surinamense L. and Montanoa grandiflora D.C., were analyzed to determine the composition of the essential oil and to search for phototoxic compounds. Three parts of the plants were studied, inflorescence, stems and leaves. Intra and interspecific differences were found in the essential oil composition, which was determined by gas chromatography. In the chromato...

Objective: To describe Heliconia uxpanapensis x latispatha var. Karely, interspecific variety generated for cut flower based on commercial standards. Design/Methodology/Approach: Interspecific hand pollination was carried out between H. Gutiérrez Báez Benth. The female parent is endemic to Mexico; it presents compact growth due its pachymorphic rhizome, red and erect inflorescence, bracts in di...

Fibre properties and the biochemical composition of cell walls are important traits in many applications. For example, the lengths of fibres define the strength and quality of paper, and lignin content is a critical parameter for the use of biomass in biofuel production. Identifying genes controlling these traits is comparatively difficult in woody species, because of long generation times and ...

Tomato plants harboring the ripening-inhibitor (rin) mutation yield fruits that fail to ripen. Additionally, rin plants display enlarged sepals and loss of inflorescence determinacy. Positional cloning of the rin locus revealed two tandem MADS-box genes (LeMADS-RIN and LeMADS-MC), whose expression patterns suggested roles in fruit ripening and sepal development, respectively. The rin mutation a...
