BACKGROUND AND AIMS In clonal plants producing vegetative offspring, performance at the genet level as well as at the ramet level should be investigated in order to understand the entire picture of the population dynamics and the life history characteristics. In this study, demography, including reproduction and survival, the growth patterns and the spatial distributions of ramets within genets...

     Mulches are relatively new landscape components and are becoming recognized for their environmental and aesthetic outcomes on urban landscapes especially in arid environments. However, the effects of mulches on landscape plants have not been extensively discussed. This study examined the effects of organic and inorganic mulches on the performance of a widely used herbaceous drought toleran...

in order to evaluate the quantitative and qualitative forage characteristics of different sainfoin ecotypes, a field experiment was conducted in a randomized complete block design (rcbd) with three replications at the research station of agricultural college of shahrekord university. in this experiment, the amount of wet and dry weight of above-ground plants, plant height, and the protein and f...

BACKGROUND AND AIMS The timing of flowering and summer dormancy induction plays a central role in the adaptation of Mediterranean geophytes to changes in the length of the growth season along rainfall gradients. Our aim was to analyse the role of the variation in the responses of flowering and summer dormancy to vernalization, daylength and growth temperature for the adaptation of Poa bulbosa, ...

In Arabidopsis, the MADS-box protein encoded by FLOWERING LOCUS C (FLC) is a repressor of flowering. Vernalization, which promotes flowering in the late-flowering ecotypes and many late-flowering mutants, decreases the level of FLC transcript and protein in the plant. This vernalization-induced reduction in FLC transcript levels is mitotically stable and occurs in all tissues. FLC activity is r...

The Funding Statement should read: "This work was supported by a grant by the Bundesministerium für Bildung und Forschung (BMBF; GerontoMitoSys 0315584A) and the LOEWE excellence initiative of the State of Hesse within the framework of the Cluster for Integrative Fungal Research (IPF) to...

Plants precisely time the onset of flowering to ensure reproductive success. A major factor in seasonal control of flowering time is the photoperiod. The length of the daily light period is measured by the circadian clock in leaves, and a signal is conveyed to the shoot apex to initiate floral transition accordingly. In the last two decades, the molecular players in the photoperiodic pathway ha...

Reproductive strategies, sexual selection, and their relationship with the phenotype of individuals are topics widely studied in animals, but this information is less abundant for plants. Variability in flowering phenology among individuals has direct impact on their fitness, but how reproductive phenology is affected by the size of the individuals needs further study. We quantified the floweri...

Flowering phenology and synchrony with biotic and abiotic resources are crucial traits determining the reproductive success in insect-pollinated plants. In seasonal climates, plants flowering for long periods should assure reproductive success when resources are more predictable. In this work, we evaluated the relationship between flowering phenology and synchrony and reproductive success in Hy...

zThe coding sequence is compared for each pair of genes. Comparisons were done using the gap program of the Wisconsin GCG sequence analysis package. yCHS = chalcone synthase; CHI = chalcone isomerase; DFR = dihydroflavonol reductase. xFirst row for each plant pair presents the percent amino acid similarity. wSecond row for each plant pair presents the percent amino acid identity. vThird row for...
