BACKGROUND AND AIMS In spite of recent phylogenetic analyses for the Chenopodiaceae-Amaranthaceae complex, some morphological characters are not unambiguously interpreted, which raises homology questions. Therefore, ontogenetic investigations, emphasizing on 'bracteoles' in Atripliceae and flowers in Chenopodioideae, were conducted. This first paper presents original ontogenetic observations in...

Grapevine flowering and fruit set greatly determine crop yield. This paper presents a new smartphone application for automatically counting, non-invasively and directly in the vineyard, the flower number in grapevine inflorescence photos by implementing artificial vision techniques. The application, called vitisFlower(®), firstly guides the user to appropriately take an inflorescence photo usin...

The impact of the season on flowering time and the organization and morphogenesis of the reproductive structures are described in three tomato mutants: compound inflorescence (s), single flower truss (sft), and jointless (j), respectively, compared with their wild-type cultivars Ailsa Craig (AC), Platense (Pl), and Heinz (Hz). In all environmental conditions, the sft mutant flowered significant...

Liparis lili/olia (L.) Richard and Tipularia discolor (Pursh) Nutall. are common terrestrial orchids in deciduous forests of eastern North America. Although the species have different breeding systems, fruit production in both species is pollinator limited. Liparis is self-incompatible while Tipularia is selfcompatible but anther cap retention promotes outcrossing. Annual variation in the numbe...

Phenotypic analysis of single and multiple mutants as well as in situ localization analysis of the expression patterns of floral genes have revealed that the FIL AMENTOUS FLOWER (FIL) gene plays important roles in establishing the inflorescence in Arabidopsis. As previously reported, the fil mutant generates clusters of both filamentous structures and flowers with floral organs of altered numbe...

Unusual gender types in some Pistacia species are considered as useful material for pistachio breeding. In this report, the inflorescence characteristics of an exceptional monoecious Pistacia atlantica Desf. tree population were presented. The gender distribution was highly complex and variable among the trees. Some of the branches bore only female or male inflorescences. Also, some branches bo...

The effect of inflorescence number and distribution along the shoot on the level of fruit-set was studied using `ON' year olive trees with a high level of floral differentiation. Reduced levels and different inflorescence distribution patterns were created artificially by hand inflorescence thinning. In most cases, removal of up to 50% of the inflorescences had either no effect on the total amo...
