The rooting of rootstocks is considered a critical point in the production high-quality grapevine planting material. To maximize cutting rhizogenesis process, plant hormones, such as auxins, are used for development adventitious roots. In addition, some groups biostimulant have their main role root system, ensuring good growth aerial part. However, research using algae extract-based biostimulan...

The compound eye of the Golden Birdwing, Troides aeacus formosanus (Papilionidae, Lepidoptera), is furnished with three types of ommatidia, which are clearly different in pigmentation around the rhabdom. Each ommatidium contains nine photoreceptors, whose spectral sensitivities were analyzed electrophysiologically. We identified nine spectral types of photoreceptor with sensitivities peaking at...

We present radio observations at three frequencies and contemporaneous optical monitoring of the peculiar BLLac object AO0235+164. During a three-week campaign with the VLA we observed intraday variability in this source and found a distinct peak which can be identified throughout the radio frequencies and tentatively connected to the R-band variations. This event is characterized by unusual pr...
