An interferometric confocal method and assembly for terabyte volume optical data memories couples two-beam spectral interferometry to chromatic confocal technology and permits a longitudinal splitting of foci in the memory volume, with the foci having limited diffraction. A spectrometer is located downstream of the interferometer with confocal discrimination in the beam path. A diffractive optical zone lens (DOZE) with a usage of the first diffraction order is introduced into the interferometric beam path to achieve longitudinal chromatic splitting. The interferometer can be a fibre-coupled interferometer with a retroreflector in the fibre-coupled reference arm and with wavelength-dependent optical path difference modification by dispersion or diffraction. The optical path difference in the interferometer is set so that easily detectable wavelets are formed from detectable interferograms by spectral analysis.

The invention discloses an SDT (semi dwarf and high-tillering) gene for decreasing Oryza sativa plant height, enhancing lodging resistance, increasing tiller number and yield, and its application. The SDT gene coding is OsmiR156h. In semi dwarf and high-tillering SDT Oryza sativa mutant, the length of the mRNA 3'-UTR transcribed from the SDT gene is shorter than that of the 3'-UTR transcribed from a wild type SDT gene, resulting in high SDT gene transcription level than expression level of the wild type SDT gene. Genetic analysis shows that SDT is a semidominant mutation, which can inhibit longitudinal splitting of stem cells to control the internode length and plant height, thereby improving the lodging resistance of Oryza sativa; at the same time, the SDT gene can increase effective tiller number of Oryza sativa, thereby improving grain number and yield per spike.
