Uneven skin coloration of early ripening table grapes is characterized by a lack of coloring berries within a cluster and the failure of some berries to develop color even with an uncertain delay of harvest. Biostimulants and plant growth regulators are known to have considerable roles on skin color development in the course of grape maturation. This study was carried out to compare the effects of different biostimulant doses, including 0, 1000, 2000 and 4000?ppm (BSt 0, BSt 1, BSt 2 and BSt 4, respectively) with or without gibberellic acid (GA3; 20?ppm) on grape characteristics and chemical composition of early ripening cv. Cardinal grape. Study results of cv. Cardinal grape revealed that alone effects of biostimulant doses had more effective on grape characteristics, total anthocyanin content and total phenolic compounds content from phytochemical characteristics. Although different foliar spray applications had varying effects on physical and chemical parameters; BSt 2 application had especially more superior effects on grape growth and phytochemical characteristics of cv. Cardinal grape.  相似文献

The estimation of antioxidants in fruit, vegetables, beverages, and foodstuffs has been discussed in a great number of scientific studies, but until now, problems concerning the analysis of antioxidant components of rosé wine has not been adequately investigated. This paper presented results of a study on antioxidant components contained in some samples of rosé wine originating from the Moravian wine growing region. The experiments involved altogether 48 samples of rosé wine made of grapes of the varieties ‘Blaufränkisch’, ‘Blauer Portugieser’, ‘Pinot Noir’, ‘Sankt Laurent’, and ‘Zweigeltrebe’. Grapes were harvested in 2013. Spectrophotometry was used to estimated antioxidant activity (53–73?mg?L?1 GAE), content of total polyphenols (152–369?mg?L?1), hydrocinnamic acid (52–148?mg?L?1), flavonols (25–294?mg?L?1) and anthocyanins (88–1754?mg?L?1). The HPLC method was used for the detection of some important antioxidants, i.?e. catechin, epicatechin, malvidin-3-glucoside, cis- and trans-resveratrol, ferrulic acid, coumaric acid and caftaric acid. This study enabled to determine basic profiles of the most important antioxidant components of the most popular Moravian red grapevine varieties. The studied wines were analyzed from several different aspects, which is not standard.  相似文献

Harvesting season for green asparagus can be extended by the use of the mother fern method and greenhouse cultivation. To evaluate seasonal variations in nutritional quality of green asparagus, the compositional profiles of fresh spears (Asparagus officialis L. cv. UC157 F1) harvested each month from March to October were compared in two locations of China using mother fern method. During the harvest season, dry matter content, soluble sugar, crude fiber, rutin and total soluble phenol in spears exhibited marked variation. Although there was no significant difference in total amino acid contents among most of months throughout the season, but quantitative changes in some specific amino acids occurred. Fresh spears harvested in warm season (from June to July) contained lower level of soluble sugars, dry matter, ascorbic acid and higher nitrate, crude fiber, total phenolics and rutin contents compared with those in cooler months. Asparagus harvested in spring accumulated relatively higher level of soluble sugar, carotenoid and chlorophyll contents than those in autumn, but total phenol and rutin contents were higher in autumn than in spring. The relationships between weather data and nutritional quality parameters of asparagus spear during harvest season were also discussed.  相似文献

This research was conducted to determine the changes in the seasonal carbohydrates of annual shoots and growth characteristics of 10 years old ‘Trakya ?lkeren’ grape variety. Grapevines are grafted on 5BB and 5C rootstocks and they were grown in heavy clay soil conditions. In the study, changes of sugar, starch and total carbohydrates were determined from bud burst to dormancy. While sugar, starch and total carbohydrates showed significant differences (P < 0.01) there were no differences between rootstocks. Although sugar, starch and total carbohydrates of shoots decreased from bud burst to blooming, they increased thereafter until vegetative growth stopped. Total carbohydrates of annual shoots have been found to accumulate in period from blooming to harvest. Total and mean leaf area, shoot length and diameter, total chlorophyll and chlorophyll a/b ratio showed significantly variation among rootstocks and phenological stages (P < 0.01). Whereas the highest chlorophyll contents were found in the blooming, it was found at the lowest through to harvest. Overall mean and total leaf area, shoot length and shoot diameter, total chlorophyll content and chlorophyll a/b ratio were significantly higher on 5BB grafted vines. In the study, 5BB rootstocks are found suitable in terms of shoot carbohydrate accumulation and growth characteristics for ‘Trakya ?lkeren’ grape variety.  相似文献

葡萄种质资源果形性状的分析   总被引:1,自引:0,他引:1  
通过分析葡萄种质的果形性状以及不同类型的果形特点,为认识葡萄种质资源果粒形状特点和育种亲本选择提供一定依据。选取820份葡萄种质材料(286份的性状来自田间实地调查,534份来自《中国葡萄志》和《中国葡萄品种》记载),对不同类型、种(species)和用途的葡萄果形特点、不同果形单果质量的分布、以及质量与其纵径和横径的相关性、不同年代选育不同果形的数量等进行分析。结果表明,倒卵圆形和长椭圆形的果粒较大,而圆形的果粒较小。欧亚种葡萄中长椭圆形和卵圆形的较多,欧美杂种葡萄中倒卵圆形的较多。鲜食葡萄较酿酒、制干和制汁葡萄果形更丰富且更狭长。黑色葡萄以圆形和近圆形为主,白色和红色葡萄中果形较为丰富。从育种进程来看,早期选育的葡萄果形以圆形为主,之后变为以圆形、近圆形和椭圆形为主,现代越来越多果形相继出现。圆形、卵圆形和倒卵圆形果粒的横、纵径与果粒质量拟合度较好。同一个葡萄品种果粒形状可能存在差异,其中椭圆形变化较为普遍。  相似文献

In a study of three seed-bearing varieties of guava and one seedless variety changes in size and specific gravity and in the content of water, titratable acid, reducing and non-reducing sugars, tannins, pectin, and ascorbic acid were recorded at intervals from fruit-set to harvest. Respiration rates were also determined during this period.

Patterns of change were generally similar in seeded and unseeded varieties, though the sugars and ascorbic acid contents rose earlier and to higher levels in the seedless than in the seeded, and the fruits matured and fell from the trees earlier.

Increasing ascorbic acid content, concurrent with declining pectin content in the seeded varieties, is consistent with the hypothesis that pectin degradation and ascorbic acid are linked, but in the seedless variety a rapid rise in the ascorbic acid content occurred during a period of pectin accumulation. The end of the initial rapid decline in respiration rate generally coincided with the beginning of reducing-sugar accumulation.  相似文献

ABSTRACT

There is an increasing demand in the market to improve strawberry quality by promoting human-health compounds content, as these may play a significant role in the prevention of chronic diseases. Strawberry cultivars, environmental conditions, and agronomical conditions have an effect on fruit characteristics; therefore, it is necessary to constantly generate information about the cultivar response to different production areas and cultural practices. The goal of this work was to evaluate the effect of two planting dates, two harvest dates, and four strawberry cultivars on total phenolic acid (gallic acid equivalent), ascorbic acid (vitamin C), and soluble solid content?titratable acidity-1 (SSC?TA-1) ratio in Huelva, Spain. Sixteen treatments resulted from the combination of four cultivars, two planting dates, and two harvest dates. Strawberry ‘Camarosa’, ‘Sabrosa’, ‘Aguedilla’, and ‘Fuentepina’ were selected for both seasons and planted on 7 Oct. (early planting) and 21 Oct. (late planting). Mid-February and mid-April were considered early and late harvest, respectively. Nutraceutical and organoleptic responses were specifics for each cultivar. The highest SSC?TA-1 ratio was observed in ‘Fuentepina’ planted late and harvested early. ‘Aguedilla’ resulted in the highest phenolic content when harvested in the late season. Additionally, phenolic content was significantly higher when using late planting combined with late harvest in most of the cultivars. Late harvested ‘Camarosa’ showed the highest TA concentration, whereas ‘Sabrosa’ resulted in the highest SSC regardless of harvesting date. Additionally, ‘Aguedilla’ and ‘Sabrosa’ showed the highest ascorbic content. Strawberry quality could be improved by selecting the adequate planting and harvesting dates according to specific cultivars.  相似文献

以欧亚种酿酒葡萄"赤霞珠"为试材,采用分光光度法,系统比较了金沙江流域和澜沧江流域不同海拔"赤霞珠"葡萄果实品质差异及其发育期品质指标的积累规律,以期为香格里拉及世界其它高海拔产区优质和特色葡萄与葡萄酒的生产提供参考。结果表明:较长的日照时长、较强的紫外辐射及较大的温差使得位于海拔2 121m的溜筒江生产的"赤霞珠"葡萄果实还原糖含量最高(265.16g·L-1),总酸最低(4.01g·L-1)。另外,位于海拔2 238m的达日生产的"赤霞珠"葡萄果实总酚、单宁和果皮总花色苷含量最高(分别为8.58mg·g-1、11.54mg·g-1和160.53A520·g-1)。金沙江和澜沧江流域各产地发育期葡萄果实可溶性固形物和还原糖含量均呈升高趋势,总酸均呈先增加后降低趋势。金沙江流域(瓦卡和达日)比澜沧江流域(西当、斯农和阿东)葡萄果实还原糖快速积累期和总酸快速下降期普遍提前2周左右。金沙江流域和澜沧江流域各产地在海拔2 000~2 250m范围内,成熟期葡萄果实中总酚、单宁和果皮总花色苷含量随着葡萄园海拔升高而升高,并均在各流域2 250m附近的葡萄园达最高。随着葡萄园海拔再度升高,到海拔最高的阿东(2 602m),其葡萄果实中总酚和单宁的含量又有所下降,但是果皮总花色苷没有显著变化。金沙江流域2个产地葡萄果实总酚和单宁含量在整个发育期内的积累规律与澜沧江流域4个产地不同,且达到最大值的时期也不同。可能是由于澜沧江流域溜筒江产地的风土条件与金沙江流域类似,其发育期内品质指标,特别是还原糖和总酸含量的变化与金沙江流域具有类似的模式。  相似文献
