设施栽培草莓新品种"红颊"引种初报 总被引:3,自引:0,他引:3
设施栽培草莓是建德市农业的支柱产业之一。自 1982年引进试种至今 ,已形成了产业化生产 ,2 0 0 3年全市栽培面积 12 0 0hm2 ,为浙江省主要草莓产区。其草莓品种 95 %是 2 0世纪 80年代后期从日本引进的“丰香”。“红颊”是日本静冈县在1993年用“章姬”与“幸香”杂交育成的用于设施栽培的良种 ,2 0 0 0年引入建德。经 3年试种 ,我们认为红颊具有生长势旺 ,产量高 ,降酸快 ,味甜 ,适合亚洲人口味的优点 ,且硬度适中、耐贮运 ,在市场上销售反映很好 ,是当前代替“丰香”的理想品种。1 生物学特性1 1 植株生长 株形直立 ,生长旺盛。平均… 相似文献

2003~2006年,从国家果树种质资源北京草莓圃和山东省果树研究所引进了5个草莓品种,在河南省漯河市进行露地栽培试验。结果表明,与对照‘全明星’和‘丰香’相比,5个品种均表现果个大,产量高,可采收期长,品种优,抗病性强。综合评价,‘红艳’果个特大、产量高、色艳、香味浓、品质极佳、较耐贮运,可作为鲜食草莓品种大力发展;‘童子一号’果实特大、风味上佳、抗病性强、耐贮运,可作为鲜食加工兼用品种大力发展。‘佐贺清香’和‘章姬’品质优良,风味好,但耐贮运性较差;‘甜查理’成熟期稍晚,采摘期较集中,香味浓,抗性强。这3个品种可作为辅助品种适当发展。 相似文献

<正>南方湿热地区露地栽培油桃存在裂果、着色差等问题,为克服这些问题,目前所采取的主姿措施是果实套袋和引进不同成熟期的品种以避开当地的不良天气。套袋虽能部分解决果实裂果问题,但在南方周年湿热气候地区套袋后的果实,果肉硬度降低,着色更差;引进不同成熟期的品种避开当地不良天气,目前只集中在早熟或特早熟品种上,由于在南方湿热地区栽培成熟期还会提早,引进的品种果实生长期更短,造成品质变差,难以进一步推广。 相似文献

Analysis of data relating to berries of 9 cultivars grown under different conditions indicates that the weight of ripe berries can be accounted for by the general equation where C is a numerical adjustment probably due to the non-spherical shape of berries, and F is the weight in g per unit area of tissue which forms the berry, and both may be characteristic of each cultivar under normal conditions.The number of achenes on perfect berries, equal to the number of ovules initiated on the flowers, is closely related to the position of the flower on the inflorescence. Expressing Rank value on the scale 1 : : : for Rank 1 : Rank 2 : Rank 3 : Rank 4, a general equation can be applied to all cultivars, although K and D may vary between cultivars and to a less extent within a cultivar. If these size factors are in fact basically genetic, a grower may have little scope for influencing berry size except during berry development in the fruiting-season. 相似文献

High Correlation coefficients have been found in the application of the formula: to data for a large number of strawberries from nine cultivars. Of the terms in the equation (Total no. of achenes — C) was found to be different in different cultivars and to be related to the position of the berry on the inflorescence, but there was no constant relationship between the achene numbers in the different ranks of berry. Whether the numbers of achenes per berry can be altered by environmental or cultural treatments was not resolved. F, a term having the dimensions of weight per area, represents weight per unit area of berry surface and seems to be constant amongst plants of a cultivar subject to uniform treatment, but differs between cultivars and treatments.The number of achenes per cm2 of surface on ripe berries is a measure of berry development in the fruiting season and may be affected by environmental and managerial factors and by internal competition between fruits and leaves on the same plant.The interactions of these factors on berry size enable two stages to be recognised at which size is determined, namely during flower formation, when achene numbers and possibly F are fixed, and during fruit development after pollination when the term for spatial distribution of achenes is settled.It is suggested that an examination of the effects of different treatments on each of the size components might enable a distinction to be drawn between the influence on yield of genetic characteristics on the one hand and intrinsically variable characteristics subject to external influence on the other hand, thus clarifying the type of research and/or development needed to enable growers to achieve maximum yields. 相似文献

Early in autumn, at the end of September or at the beginning of October, strawberry plants of the cultivars ‘Glasa’ and ‘Tioga’ were transferred from outdoors to separate phytotron glasshouses at constant temperatures of 10° and 14°C. In November a number of these plants were chilled at 3°C for 0 to 4 weeks and subsequently forced; the rest remained at 10° and 14°C until June.The plants kept at 10°C and subsequently chilled and forced, grew faster and more vigorously than those pretreated at 14°C. The 14° plants showed more pronounced growth differences resulting from the length of the chilling treatments than did the 10° plants. Those remaining continuously at 10° developed vigorously from March onwards, while those at 14°C retained their flat appearance into June. These results showed that a continuous temperature as high as 10°C was still able to break dormancy in the strawberry plants, while 14°C was ineffective. 相似文献
