30S. MAN ŞI C. DRAICAEFFECT OF PLANTING TIME ON POTATO YIELD AND INFECTIONVIRUSES CARRIED BY APHIDES IN SEED POTATO CROPSSummaryTo improve the technology of the seed potato cropping in the closed zones, three triennalcycles of polifaetorial experiments were carried out in 1969-1974 at Le.P.e. Braşov. Theresults regarding the effeet of the planting on limiting the severe virus diseases on varietyDesiree are discussed. If the fields are isolated, the delay of planting by 15 days aHer theoptimum time (Apri! 10-20) increases the infeetion by PVY with 25% and by PLRV with58%. If the virus diseased plants are not discarded and the treatments by aphicides are notused, the favorable effeet of the .optimum planting time on the infeetions by PLR.V decreasesvery significantly (25-52%).An yield of 13.6 Uha seed-potato (of 30-55 mm) representing 65% from the total iuberyield and aminimum virotical infeetion (2.37% in 11) can be realized only by using on optimumleve the folIowing faetors preventing the spread of the virus diseases: the isolation betweenbiological categories, the planting time, the virus diseased plant discarding and the earlykilling of the haulms. By planting in good time the growth interruption can be postponedaHer the date of the maximum flight of the aphids 20-30 days for Il and 10-20 days forsuperelite and elite (in dependance on the class of resistance of the varieties); fhe yieldincreases by 15-83%.in that case.EINFLUSS DER PFLANZEPOCHE AUF DEN ERTRAG UND AUFDIEINFEKTION MIT VON BLATTLÂUSEN DBERTRAGENENVIREN IN DEN KARTOFFELKULTUREN FOR PFLANZGUTZusammen{assungIn der Periode 1969-1974 wurden bei Le.c.S. Braşov eine Serie polifaktorieJler Versuche,in drei dreijăhrigen Zyklen, durchgefiihrt, hinsichtlich der Verbesserung cler Technologiezur Erzeugung und Vermehrung der Pflanzgutkartoffel in geschlossenen Zonen.Es werden die Ergebnisse gezeigt, betreffend den Einfluss der Pflanzepocheauf dieEinschrănkung der Infektion mit schădlichen Viren bei der Kartoffelsorte Desiree. UnterBedingungen der Isolierung der Kartoffelkulturen bewirkt die Verspătung des PfJanzensmit 15 Tagen gegeniiber der giinstigsten Epoche (10.-20. Apri!) die Steigerung der Infektionum 25% fiir den Virus Y und um 58% fiir den BlattrolIvirus. Das Nichtentfernen cler vonViren befallenen Pflanzen aus derKultur und die Nichtausfiihrung der BehandJungen mitInsektenbekampfungsmittel fiir die Bekămpfung der B1att1ăuse, verringern den Effekt clergiinstigsten Pflanzepoche auf die Infektionen mit dem Blattrollvirus.Den Ertrag von 19,6 tlha STAS-Pflanzgut (30-55 mm), was 65% der GesamtprodukHon darstellt und eine minimale Infektion (2,37% in Il), kann nul' dadurcherzielt werden,dass alle Faktoren zur V~)fbeugung der Verbreitung der Viruskrankheiten unter den gfinstigstenBedingungen angewandt werden; und zwar: die entspreshende Isolierung der biologischenKathegorien, das Pflanzen in der gunstigsten Epoche, die AusfUhrung der Behandlungen zurBekămpfungder BlattIăuse, das Entfernen der von Viren befallenen Pflanzen und die zeitlicheUnterbrechung der Vegetation. In dieser Hinsicht kann man durch das Pflanzen in der gunstigstenEpoche die Unterbrechung der Vegetation verschieben, und zwar um 20-30 ragevom H6hepunkt des Fluges derBlattlăuse bei Il und um 10-20 Tage bei der Superelite undElite (je nach der Widerstandsgruppe der Sorten gegeniiber den Viren), wodurch ein Mehrertragvon 15-83% erzielt wird.
