Growth characteristics such as leaf area, fresh and dry mass, and shoot length, and physiological parameters such as photosynthetic and transpiration rates, stomatal conductance, and water use efficiency were reduced by blister blight significantly more in a susceptible tea clone TES-34 than in a tolerant clone SA-6. Also the contents of total sugars, nitrogen, amino acids, proteins, polyphenols, and catechin were reduced more in diseased plant leaves. However, the reduction was more prominent in susceptible than in tolerant clone. Among the different hybrids of tea, Assam hybrid UPASI-3 was highly susceptible to blister blight followed by Cambod UPASI-27 and China UPASI-9. Similarly, tea seedling cv. Caline was highly susceptible to blister blight when compared to tea clone UPASI-3. Susceptibility of tea cultivars to blister blight infection is connected with many physical barriers including leaf area, shoot length, moisture contents, and other physiological and biochemical parameters. and R.

The paper deals with the design, fabrication and applications of the computer generated holograms. The micro-structure of the element is calculated point-by-point on the base of the diffraction theory with high resolution and fabricated using the e-beam or laser-beam direct-write lithography. The holograms of this kind are very prospective for optical beam shaping and various manipulations with optical beams. and Článek pojednává o syntetických, počítačem generovaných hologramech, jejich návrhu, realizaci a aplikacích. Mikrostruktura hologramu je napočítávána na základě teorie difrakce bod po bodu s vysokým rozlišením a posléze realizována například elektronovou nebo laserovou litografií. Prvky tohoto typu jsou perspektivní pro tvarování optických svazků a různé typy manipulací se svazky.
