TEST OF RESISTANCE OFPOPULUSXEURAMERICANACV. PANNO-NIATO THE ATTACK OFDISCOSPORIUM POPULEUM(SACC.)

SUT-TON IN THE CONDITIONS OF GORNJE POTISJE

Abstract: The simple crossing of different poplar species enables a relatively easy method of obtaining the new cultivars and clones by artificial selection, combined with production characteristics. The first step in the study of resistance of the new-ly selected individuals to parasites is the artificial infection of thecontrol plants.If the plant shows the adequate degree of resistance, it is introduced to individual sites and its behaviour to the pathogen is monitored in the conditions of natural infec-tions. After the tests with artificial infections, the cultivarPopulusxeuramericana cv.Pannonia showed satisfactory results, so its monitoring was continued in the plantation production. This paper presents the study of this cultivar resistance to the infections by the fungus Discosporiumpopuleumin natural conditions. Based on

(2)

the study results, the cultivarPannoniacan be recommended for use, especially at the sites with poorer hydrological characteristics.

Key words:Populus x euramericanacv.Pann6nia, Discosporium populeum, re-sistance/susceptibility, natural and artificial infections, cultivar

TEST OF RESISTANCE OFPOPULUSXEURAMERICANACV.PANNONIATO THE ATTACK OFDISCOSPORIUM POPULEUM(SACC.)SUTTON IN THE CONDITIONS

OF GORNJE POTISJE

Summary

After the resistance/susceptibility ofPopulusxeuramericanacv.Pannoniato artificial in-fections by the fungusDiscosporiumpopuleum was evaluated, its susceptibility was tested by nat-ural infections in plantations. For the evaluation by this method, 70 trees were examined in June 2001 at the localities Siget (40 trees) and .Hrastova suma" - oak forest (30 trees), The plants were controlled in the second year after transplanting, i.e. at the age of three years.

The average size of necroses measured in March was 0.37cm2.The size of necroses 5 months after artificial infections was 0.64 cm2.The greatest number of controlled trees (77.2%) were in the category of resistant, about 20% were in the category resistant, and the remaining two trees were in the category of low susceptibility. According to Donauber's method,Pannoniawas classified in the resistant group. The size of catlused wounds most often ranged 5-28x 10-39mm. According to Waterman's classi fication, callus formation is evaluated as class 1 and only one necro-sis was classified as the third class. The average class of callus tissue formation after Waterman is 1.13, which indicates that this cultivar is able to resist the fungal attack, i.e, in a relatively short pe-riod, to outgrow and close by meristem the wounds of the necrotic area. The observed damage by clearwings at injured places, indicate the need to check the cultivar resistance to the attack of xy-lophagous insects.

The test results as well as the field experience, show thatPopulusxeuramericanacv,

Pan-noniahas a satisfactory degree of resistance toDothichizacanker, so its application in practice can be recommended. According to the Hungarian experience, this cultivar grows especially well on the soils with poorer hydrological characteristics. Consequently, its cultivation is recommended at the drier, border poplar sites.
