摘要
在河西走廊荒漠化区域日光温室生态环境条件下,对外引的7个彩椒品种从生育周期、植株形态、光合特性及品质与抗病性等性状上进行了观察比较分析。结果表明:各参试品种生长期长短依次为:"尼瑞">"黄金甲">"太阳红">"塔兰多">"索玛">"富民五彩椒">"富康七彩椒";彩椒品种"太阳红"和"尼瑞"在生长中保持较高的净光合速率、蒸腾速率、气孔导度和胞间CO2浓度并获得高产,产量分别为6 246.87kg/667m2和5 964.09kg/667m2;同时其果实中维生素C含量、可溶性糖含量及可滴定酸含量均较高,病害发病率较低,抗病性最强,建议可在当地日光温室彩椒生产中推广应用。
Comparative analysis characters of disease resistance,quality,photosynthetic characteristics,plant morphology and growth cycle on seven color pepper varieties under the conditions of desert area in Hexi corridor were studied in this paper.The results showed that growth period from long to short of different color pepper varieties was ‘Nirui＇,‘Huangjinjia＇,‘Taiyanghong＇,‘Talanduo＇,‘Soma＇,‘Fumin Wucaijiao＇,‘Fukang Qicaijiao＇respectively,there were higher net photosynthetic rate,transpiration rate,stomatal conductance and intercellular CO2 concentration of color pepper varieties in‘Taiyanghong＇and‘Nirui＇.There were high yield of color pepper varieties in‘Taiyanghong＇and‘Nirui＇,which were 6 246.87kg/667m2 and 5 964.09kg/667m2 respectively.There were higher vitamin C content and soluble sugar content,titratable acid content,low incidence and strong resistance of color pepper varieties in‘Taiyanghong＇and‘Nirui＇.Color pepper varieties on‘Taiyanghong＇and‘Nirui＇could be applied in the local greenhouse pepper production.
