Abstract

Ker je v zadnjem času vse več neviht s točo, kar bi bil lahko rezultat globalnega segrevanja, se je precej razširilo gojenje sadnih dreves in drugih rastlin pod protitočnimi mrežami. Mreže so namenjene zaščiti pridelka pred točo zlasti v sadjarstvu in vinogradništvu. Poleg protitočnih mrež poznamo še mreže za zaščito proti vetru, proti žuželkam in senčne mreže. Mreže lahko spremenijo mikroklimo v sadovnjaku ter tako spremenijo fizikalno-kemijske in senzorične lastnosti plodov. V diplomskem delu smo raziskovali vpliv protitočnih mrež na zunanje dejavnike, kot sta prestrezanje svetlobe in temperatura. To posledično vpliva na temperaturo, barvo, velikost in zrelost plodov ter na bujnost dreves. Med kemijske spremembe prištevamo vpliv na vsebnost fotosinteznih pigmentov (klorofila in karotenoidov), primarnih in sekundarnih metabolitov (fenolne spojine) ter na posamezne antocianine v kožici plodov. Poleg naštetega pa protitočne mreže vplivajo na zmanjšanje pokanja plodov in ožigov ter na večji pojav in stopnjo intenzivnosti okužb s škrlupom.

Secondary title: ǂThe ǂeffect of anti-hail nets on crop quality
Secondary abstract: As there is an increasing number of hail storms, which are a consequence of global warming, the cultivation of crops and other plants under anti-hail nets has expanded considerably. The nets are designed to protect crops from hail, especially in fruit cultivation and viticulture. In addition to anti-hail nets, there are also nets for protection against wind and insects, and shading nets. These can change the microclimate in the orchard and consequently change physical, chemical and sensory characteristics of fruits. In my undergraduate thesis, I investigated the influence of the anti-hail nets on external factors, such as solar radiation interception and temperature. The use of anti-hail nets affects the temperature, color, size and ripeness of the fruit as well as the tree vigour. Chemical changes are mostly the effects on content of photosynthetic pigments (chlorophyll and carotenoids), primary and secondary metabolites (phenolic compounds) and individual anthocyanins in the fruit skin. Apart from this, the anti-hail nets help to reduce fruit cracking and sunburns but causes higher occurrence and intensity level of AS infection on apples.
