中文摘要 | 篩選茄科番椒屬(Capcicum) 跟砧124種品系,包括6個甜椒雜交品種,經疫病Phytophthorablight (PB)、青枯病bacterial wilt (BW)接種後,甜椒雜交種感病率83-100%。為能篩選出耐病辣椒品系供作甜椒根砧,進行耐疫病、青枯病檢定。發現19個辣椒品系具耐PB、BW病害,其中l3種品系更兼耐淹水性。甜椒品種嫁接在15種辣椒砧木,平均耐病率各分別為PB(43.8%)和BW(46.9%)。觀察其中辣椒品系9852-54,CCA 3336,PBC 535,TOOM-l和自根苗,經PB、BW病菌接種過後之根部均有損害。但全部嫁接苗株高,葉面積生長率比自根苗增加,推測砧木與穗木之間具有高親和性;而盆栽試驗中嫁接苗砧木使用。242-61和0242-62辣椒品系,不但具抗耐土壤PB、BW和高溫高濕,且親和性佳。此試驗利用嫁接苗根砧耐疫病與青枯病基因特性,減低土壤病害發生與對增強甜椒在高溫高濕之夏季栽培技術提升有其發揮作用。 |
英文摘要 | A survey for diseases resistance in AVRDC-pepper linees, showed that among the 124 lines tested inc1uding six commercial sweet pepper cu1tivars, 19 accessions exhibited very high resistance/tolerance to soil borne phytophthora blight (PB) and bacterial wilt (BW) and 13 accessions with additional flooding tolerance. All six commercial sweet pepper cultivars were very susceptible to both diseases. The sweet pepper cu1tivar grafted onto resistant chili-stock increased survival rate to PB (43.8%) and BW(46.9%), the root of 9852-54 ,CCA 3336、PBC 535、TOOM-l and the ungrafted pepper cu1tivar were severely damaged. The grafts tended to have higher expansion indicating good compatibility on plant height and leaf-area between scion and rootstocks. Lines of 0242-61and 0242-62 used as a rootstock not only give the grafts tolerance to PB and BW pathogens, but also against to high soil temperature and moisture, in which enhanced sweet pepper yields increasing during the hot-wet in summer. |
