In the scope of genetic, morphological and phenological research genus Tilia in Bosnia Herzegovina, with control populations Germany, multibracteate silver-leaved linden (T. tomentosa Moench.) was discovered Mostar. addition to usual primary bract, there are also bracts second third order, which as phenomenon is, our knowledge, new for science. Since vary size, well shape, additional do not app...

Field trials conducted in 2008 and 2009 investigated whether plot size affects incidence of white flower anther injury by tarnished plant bug (Lygus lineolaris (Palisot de Beauvois)) in host plant resistance (HPR) evaluations. The three cotton lines evaluated in the trial included a susceptible frego bract line (RBCDHGPIQH-197) and 2 standards, SureGrow (SG) 105 and Deltapine (DP) 393. Samplers...

Freshly harvested white asparagus (Asparagus of®cinalis L.) spears (about 500 g per package) were over-wrapped with a 16 mm stretch ®lm. Packages were kept at 2.58C, 58C, 108C, 158C, 208C and 258C under continuous darkness or light (15 1.9 W mÿ2) for 6 days. At all temperatures, an atmosphere of 4.5±6.9% CO2 and 3±6.7% O2 developed during the ®rst hour; after 8 h, CO2 increased to a maximum of ...

The pathogenesis of byssinosis has been attributed to several different immunopathologic mechanisms, including a type III (immune complex) pulmonary injury. To further examine this type III theory, sera (Monday preshift) from 59 cotton textile workers were examined by gel diffusion and counterimmunoelectrophoresis for precipitating antibodies to aqueous extracts of cotton bract, carpels, stems,...

Floral morphology often directly influences interactions with pollinators, but less is known about the role of extrafloral structures. We studied the relationship between bract motility, floral structural specialization and pollination in Dalechampia aff. bernieri, an endemic Madagascan species with floral structures indicating specialized buzz-pollination.Wemeasured circadian bract angles in 4...

• Both floral rewards and advertisements can be important in the attraction of pollinators, but few studies have separated the individual contributions of rewards and advertisements to fitness. • Here, we investigated selection by pollinators on individual blossoms in Dalechampia schottii. This Neotropical vine, endemic to the Yucatán Peninsula, rewards bees by secreting fully visible, deep-blu...

PREMISE OF THE STUDY Investigations of inflorescence architecture offer insight into the evolution of an astounding array of reproductive shoot systems in the angiosperms, as well as the potential to genetically manipulate these branching patterns to improve crop yield and enhance the aesthetics of horticultural species. The diversity of inflorescences in the economically important family Oleac...

Exogenous ethylene, or ethephon, has been widely used to induce pineapple flowering, but the molecular mechanism behind ethephon induction is still unclear. In this study, we cloned four genes encoding ethylene receptors (designated AcERS1a, AcERS1b, AcETR2a, and AcETR2b). The 5' flanking sequences of these four genes were also cloned by self-formed adaptor PCR and SiteFinding-PCR, and a group ...

Noble gases that form clathrate hydrates when dissolved into water and restrict water molecule activity can prolong the shelf life of fruits and vegetables. Physiological and physical aspects of asparagus spears treated with mixtures of compressed (1.1MPa absolute) argon (Ar) and xenon (Xe) (2:9 in partial pressure) were compared with controls under normal preservation in modified atmosphere pa...

Important goals in understanding leaf development are to identify genes involved in pattern specification, and also genes that translate this information into cell types and tissue structure. Loss-of-function mutations at the JAGGED (JAG) locus result in Arabidopsis plants with abnormally shaped lateral organs including serrated leaves, narrow floral organs, and petals that contain fewer but mo...
