Effect of orchard site and climatic conditions on plant nematode density levels

Phytoparasitic nematodes are commonly found in the soil and their presence can lead to plant diseases, weaker growth, reduced yields lower fruit quality. A study conducted 2006–2009, involving monitoring of climatic conditions, identified influence precipitation temperature on number nematodes, 7 sites within a cherry orchard. Soil samples assess nematode populations were taken from that differed terms cultivation age: 5 orchards established different years. Not all taxa responded same way increase. Members families Belonolaimidae, Trichodoridae genus Aphelenchus increased with rising temperatures. The negative water balance limited layer up 30 cm, whereas increase moisture had positive effect development Paratylenchus spp., mebers family Hoplolaimidae Heterodera. largest total was strip cultivated agricultural crops after orchard liquidation. However, parasitic accounted for at low levels (17%). size fruits trees growing large decreased simultaneous soluble solids firmness.
