Present study has been carried out to understand the mating strategies of Eremurus himalaicus Baker., important medicinal endemic plant, for its sustainable utilization. The inflorescence architecture, large numbers attractive flowers, presence sterile flowers which give specific arrangement inflorescence, coloured, androecia and nectaries attract pollinators. Protoandry, moderate high pollen o...

Arabidopsis (Arabidopsis thaliana) SUPERMAN (SUP) plays a role in establishing a boundary between whorls 3 and 4 of flowers and in ovule development. We characterized a Petunia hybrida (petunia) homolog of SUP, designated PhSUP1, to compare with SUP. Genomic DNA of the PhSUP1 partially restored the stamen number and ovule development phenotypes of the Arabidopsis sup mutant. Two P. hybrida line...

Abstract The variability of metric traits has been studied in 20 Kazakhstan populations three Nitraria species ( N. schoberi L., sibirica Pall., and komarovii Iljin & Lava ex Bobrov). According to the results, differs from small leaves, fruits, seeds, as well structural features inflorescences flowers. is characterized by a greater number flowers per inflorescence (25–66 on average) than (1...

Curcuma heyneana or temu giring is mainly popular for medicinal and beauty purposes; however due to its attractive inflorescence, it potential ornamental plant. This study aims describe morphological characteristics examine gamma irradiation effect on plant growth of C. heyneana. The method applied was acute irradiation, with 6 doses 0 Gy (control), 10 Gy, 20 30 40 50 Gy; 3 replications, 15 rhi...

tuberose (polianthes tuberosa l.) is one of the most important cut flowers in iran. this research was conducted to investigate the effects of spraying a mixture of amino acids on the physiological and morphological characteristics of tuberose. the experiment was carried out in two successive years (2009 and 2010) using two tuberose cultivars ‘dezfuli’ and ‘mahallati’. the experiment was arrange...

Flower production and crop yields are highly influenced by the architectures of inflorescences. In the compound inflorescences of tomato and related nightshades (Solanaceae), new lateral inflorescence branches develop on the flanks of older branches that have terminated in flowers through a program of plant growth known as "sympodial." Variability in the number and organization of sympodial bra...

Sterile and fertile flowers are an important evolutionary developmental (evo-devo) phenotype in angiosperm flowers, playing important roles in pollinator attraction and sexual reproductive success. However, the gene regulatory mechanisms underlying fertile and sterile flower differentiation and development remain largely unknown. Viburnum macrocephalum f. keteleeri, which possesses fertile and ...

BACKGROUND AND AIMS Resource allocation to flowers, fruits and seeds can vary greatly within an inflorescence. For example, distal fruits are often smaller and produce fewer and smaller fruits and seeds than more basal fruits. To assess the causes and functional significance of intra-inflorescence variation, pollen and resources were manipulated to test whether such patterns could be altered wi...

BACKGROUND Most angiosperms present flowers in inflorescences, which play roles in reproduction, primarily related to pollination, beyond those served by individual flowers alone. An inflorescence's overall reproductive contribution depends primarily on the three-dimensional arrangement of the floral canopy and its dynamics during its flowering period. These features depend in turn on character...
