PREMISE OF THE STUDY Controversy is ongoing regarding the importance of pollinator-mediated selection as a source of observed patterns of floral diversity. Although increasing evidence exists of pollinator-mediated selection acting on female reproductive success, there is still limited understanding of pollinator-mediated selection on floral traits via male reproductive success. Here we quantif...

We present the initial phenotypic characterization of an Arabidopsis mutation, terminal flower 1-1 (tfl1-1), that identifies a new genetic locus, TFL1. The tfl1-1 mutation causes early flowering and limits the development of the normally indeterminate inflorescence by promoting the formation of a terminal floral meristem. Inflorescence development in mutant plants often terminates with a compou...

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 close to impossible correct controlling of the temperature and light intensity is the main limiting factors of growing plants in the plastic covered greenhouses. quality and vase life of cut flowers are mostly influenced by greenhouse temperature. alstroemeria needs cold temperature for growth and flowering. in the current study, the such changes in vase life and flower quality as stem leng...

Plants often grow in clusters of various sizes and have a variable number of flowers per inflorescence. This small-scale spatial clustering affects insect foraging strategies and plant reproductive success. In our study, we aimed to determine how visitation rate and foraging behaviour of pollinators depend on the number of flowers per plant and on the size of clusters of multiple plants using D...

Flowering plants go through several phases between regular stem growth and the actual production of flower parts. The stepwise conversion of vegetative into inflorescence and floral meristems is usually unidirectional, but under certain environmental or genetic conditions, meristems can revert to an earlier developmental identity. Vegetative meristems are typically indeterminate, producing orga...
