The aim of the thesis is to focus on the information concerning the physiological bunchstem necrosis and berry shrivel. I had to deal with possible causes and consequences. In conclusion I've formulated recommendations for growers. In the first part, I've defined the basic concepts (grape, berry, stem), continuing with bunchstem necrosis in general. The following chapter describes the abiotic causes of berry shrivel necrosis and then those biotic. The next chapter deals with the general part of physiological bunchstem necrosis and then bunchstem necrosis due to magnesium deficiency. In the last part of third chapter I present the world studies of this issue. |
