Abstract Heliconias are tropical plants with ornamental potential. These particularly used in the floriculture industry because of their exotic colors and shapes. Species characterization is important for selection genotypes plant market subsequent application studies genetic improvement. The aim this study was to estimate divergence Heliconia densiflora psittacorum accessions based on quantita...

The mode of action of the thermogenic inducers (salicylic acid, aspirin, and 2,6-dihydroxybenzoic acid) in the appendix of the Sauromatum guttatum inflorescence is poorly understood. Using ESI-MS and light scattering analysis, we have demonstrated that NAD(P) reductase like protein (RL) is the salicylic acid receptor in the Sauromatum appendix. RL was self-assembled in water into a large unit w...

dom’ reached anthesis most rapidly, while plants of ‘Mathilde Gütges’ and ‘Merritt’s Supreme’ were the slowest to f-lower. Table 2 represents days to anthesis and not days to salable color. In general, plants were salable, based on sepal color, ≈10 days before anthesis, so subtracting 10 days from data in Table 2 gives forcing times (from start to sale) for these cultivars when a 62F (17C) mini...

The postharvest life of different cultivars of kalanchoë plants (Kalanchoë blossfeldiana Poelln.) varied widely. The display life of plants of ‘Nadia’ was much longer than that of plants of ‘Debbie’ (10 weeks compared with 7 weeks). During display life, senescing flowers were replaced by opening buds and the difference in display life was primarily a function of differences in life of the indiv...

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...
