bunt incidence resistance sources of resistance winter wheat cultivars
2016/12/8
Resistance to common bunt and to dwarf bunt in winter wheat cultivars recently registered in the Czech Republic was studied in artificially inoculated field trials in the years 2013−2015. In tri...
Dwarf galaxies are enigmas wrapped in riddles. Although they are the smallest galaxies, they represent some of the biggest mysteries about our universe. While many dwarf galaxies surround our own Milk...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA)have discovered that a dim, cool dwarf star is generating a surprisingly powerful magnetic field, one that rivals the most...
Dark matter is called "dark" for a good reason. Although they outweigh particles of regular matter by more than a factor of 5, particles of dark matter are elusive. Their existence is inferred by thei...
