Sweet whey and UF-milk permeate, the nutritional and valuable dairy by-products were successfully used in yoghurt drink manufacture. Sweet whey, UF-milk permeate or water were added to fresh cow’s milk in a ratio of (1:1). Yoghurt drink cultures: ABT probiotic yoghurt culture (Lactobacillus acidophilus, Bifidobacterium bifidum, & Streptococcus thermophilus) and YCX11 thermophilic yoghurt culture (Streptococcus thermophilus & Lactobacillus delbrueckii subsp. bulgaricus) were also used. The higher total solid (TS) content were shown in sweet whey yoghurt drink samples meanwhile, water samples were the lowest. ABT yoghurt drink samples exhibited pH values slightly lower than that of YC-X11 when compared at the same order. Lb. acidophilus was recorded a developing count in water yoghurt drink treatment along 14 days meanwhile; sweet whey yoghurt drink treatment recorded the highest developing count up to 21 days of storage at (4 ± 1°C). The lower TS content the lower developing count of Lb. acidophilus. The joint growth of S. thermophilus and (B. bifidum & Lb. acidophilus) was better more than that with Lb. bulgaricus even at the low levels of the TS. No yeast and mold counts were detected in all treatments when fresh and during storage up to the day 21. For the sensory character assessed sweet whey yoghurt drink treatments were the most preferred and UF-milk permeate yoghurt drink was slightly less acceptable. Three replicates were carried out for each treatment and the data obtained were statistically analyzed at p ≤ 0.05.
甜乳清和脱脂乳渗透,成功地将营养价值高的乳制品副产品应用于酸奶饮料的生产。在鲜奶中按1:1的比例加入甜乳清、uf -牛奶渗透液或水。酸奶饮料培养物:ABT益生菌酸奶培养物(嗜酸乳杆菌、两歧双歧杆菌和嗜热链球菌)和YCX11嗜热酸奶培养物(嗜热链球菌和德尔布鲁氏乳杆菌亚种)。保加利亚)也被使用。甜乳清酸奶饮料样品中总固体含量最高,水样中最低。ABT酸奶饮料样品的pH值略低于YC-X11。同时,在水酸奶饮料中记录嗜酸杆菌在14天内的发展计数;在(4±1°C)条件下,甜乳清酸奶饮料处理在21天内的发芽率最高。TS含量越低,嗜酸杆菌的发育计数越低。即使在低TS水平下,嗜热链球菌与两歧双歧杆菌和嗜酸杆菌的联合生长也优于保加利亚杆菌。在新鲜和储存21天内,所有处理均未检测到酵母菌和霉菌计数。对于感官特性的评价,甜乳清酸奶饮料是最受欢迎的,而uf -牛奶渗透酸奶饮料的可接受程度略低。每个处理进行3个重复,所得数据以p≤0.05进行统计学分析。

The present study was carried out during two successive seasons of 2012 and 2013 in a private vineyard located at Sadat city, Menofia Governorate, Egypt The main target is the detection of the proper rootstock which achieve the highest compatibility (Congeniality) degree for the Flame seedless cv, with good survival % and healthy growth for the obtained grafts especially vegetative growth of scion and root system growth of the rootstock. The survival percentage varied significantly according to rootstock type. Freedom rootstock recorded the highest survival percentage (80.00 and 83.33 %) and F.C.C (2.41 and 2.53) in 2012 and 2013 seasons, respectively. While, Harmony rootstock recorded the lowest survival percentage (60.00 and 66.67 %) and F.C.C (1.51 and 1.82) in both seasons, respectively. Meanwhile, difference in F.C.C. value between Freedom and Salt creek was insignificant in both seasons. Freedom rootstock recorded the maximum values of scion shoot length (93.55 and 95.86 cm) and leaf area (95.24 and 105.49 cm2) in 2012 and 2013 seasons, respectively. While, Harmony rootstock achieved the minimum values of shoot length (67.43 and 71.67 cm) and leaf area (73.37 and 79.60 cm2) in the two studied seasons, respectively. However, differences in both shoot length and between Freedom and Slat creek rootstocks are insignificant in both seasons. Freedom rootstock recorded the maximum figures of the aerial portion fresh weight (7.65 and 8.89 g), fresh weight of root system (2.94 and 4.23 g), dry weight of the aerial portion (2.07 and 2.52 g) and dry weight of root system (1.7 and 2.4 g) in the two seasons, respectively. While, Harmony rootstock showed the minimum values of fresh weight of aerial portion (5.65 and 6.33 g), fresh weight of root system (2.30 and 2.91 g), dry weight of the aerial portion (1.65 and 1.81 g) and dry weight of root system (1.34 and 1.63 g) in the two studied seasons, respectively. Meanwhile, differences in fresh wt. and dry wt. of aerial portion between Freedom and Salt creek were insignificant in both seasons. The obtained results revealed that canes of Freedom rootstock exhibited the largest total indoles (0.29 and 0.30 mg/g F.W.), free indoles (0.25 and 0.26 mg/g F.W.). But they showed the lowest total phenols (0.17 and 0.15 mg/g F.W.) and free phenols (0.15 and 0.13 mg/g F.W.) in 2012 and 2013 seasons, respectively. On the contrary, canes of Harmony rootstock exhibited the minimum values of total indoles (0.24 and 0.23 mg/g F.W.) and free indoles (0.19 and 0.20 mg/g F.W.) and the highest figures of total phenols (0.24 and 0.23 mg/g F.W.) and free phenols (0.20 and 0.18 mg/g F.W.) in both seasons, respectively. However, no significant differences were detected in total indoles and total phenols between Freedom and Slat creek rootstock in both seasons.
本研究于2012年和2013年连续两个季节在埃及Menofia省Sadat市的一个私人葡萄园进行,主要目标是检测适合的砧木,该砧木对火焰无核cv具有最高的亲和性(亲和)程度,获得的嫁接具有良好的成活率和健康的生长,特别是接穗的营养生长和根系的生长。不同砧木类型的成活率差异显著。自由砧木在2012年和2013年的成活率分别为80.00和83.33%和2.41%和2.53%。和谐砧木的成活率最低,分别为60.00和66.67%,F.C.C为1.51%和1.82%。同时,两个季节Freedom和Salt creek的fcc值差异不显著。自由砧木的接穗长(93.55 cm)和叶面积(95.24 cm和105.49 cm2)分别在2012年和2013年达到最大值。和谐砧木的茎长和叶面积分别为67.43和71.67 cm和73.37和79.60 cm2。然而,在两个季节中,自由和石板溪砧木的茎长差异不显著。自由砧木的地上部鲜重(7.65和8.89 g)、根系鲜重(2.94和4.23 g)、地上部干重(2.07和2.52 g)和根系干重(1.7和2.4 g)在两个季节分别达到最大值。和谐砧木地上部鲜重(5.65和6.33 g)、根系鲜重(2.30和2.91 g)、地上部干重(1.65和1.81 g)和根系干重(1.34和1.63 g)在两个研究季节分别最小。与此同时,自由河和盐溪两季空中部分的干、鲜水分含量差异均不显著。结果表明,自由砧木的总吲哚含量(0.29和0.30 mg/g F.W.)和游离吲哚含量(0.25和0.26 mg/g F.W.)最高。但总酚含量(0.17和0.15 mg/g F.W.)和游离酚含量(0.15和0.13 mg/g F.W.)分别在2012和2013季节最低。与此相反,和谐砧木茎秆的总吲哚(0.24和0.23 mg/g F.W.)和游离吲哚(0.19和0.20 mg/g F.W.)最小,总酚(0.24和0.23 mg/g F.W.)和游离酚(0.20和0.18 mg/g F.W.)最高。但两种砧木的总吲哚和总酚含量无显著差异。

Innovative and sustainable tools such as biostimulant-based substances play an important key role in the development of environment friendly viticultural strategies to improve yields and fruit quality. In this study, we investigated the effect of foliar spray application of two biostimulants, seaweed extracts made from Ascophyllum nodosum and effective microorganisms, alone or combined with each other, on increasing the vegetative growth of Vitis vinifera cv. Ruby Seedless. Two concentrations of (1g/L and 2g/L) were used for each substance to asset their impact on yield, chemical characteristics of berries, leaf area shoot length. All treatments showed a stimulatory effect for studied parameters. The results indicate that the vines treated with the lower levels of EM 1g/L combined with higher levels of seaweed A. nodosum 2g/L produced the highest absolute yield and least shot berries % relative to the untreated vines.

Agri-food marketing in developing countries is usually seen from a micromarketing perspective, and to a relatively lesser degree, from a macromarketing perspective. However, there is also another perspective within agri-food marketing that is mesomarketing. In this regard, the research attempted to further research the realm of agri-food mesomarketing and attempt to better ascertain, assess and diagnose mesomarketing in agri-food marketing in developing economies. The findings from the research provided that agri-food mesomarketing has an important role to play, not only as per its conduit between micromarketing and macromarketing, but for its importance per se. In fact, the research findings provided that a more holistic approach to agri-food marketing is important i.e. the combination and integration of micromarketing, mesomarketing and macromarketing. The research also found the importance of agri-food mesomarketing in terms of, for example, further developing regional and/or provincial agri-food marketing systems within a country; developing city, town and village agri-food marketing systems; developing networks of local vertical, horizontal and facilitating marketing systems; developing markets in both rural and urban areas; facilitating and enhancing community agri-food marketing systems, community and non- autochthonous community-based enterprise marketing practices and group collective marketing practices ; fostering growth poles and economic corridors as well as in-country regional and rural development policies. However what also emerged from the research findings was the evident lack of research specifically on agri-food mesomarketing, a lack of research conducted taking a specific agri-food mesomarketing perspective in particular and also a lack of research on agri-food mesomarketing practices.
发展中国家的农业食品营销通常是从微观营销的角度来看的,在相对较小的程度上是从宏观营销的角度来看的。然而,在农产品营销中还有另一种观点,即中介营销。在这方面,本研究试图进一步研究农产品中介营销领域,试图更好地确定、评估和诊断发展中经济体农产品营销中的中介营销。研究结果表明,农业食品中介营销不仅在微观营销和宏观营销之间发挥着重要作用,而且其本身也很重要。事实上,研究结果表明,更全面的农业食品营销方法是重要的,即微观营销、中介营销和宏观营销的结合和整合。研究还发现了农业食品中间营销的重要性,例如,在一个国家内进一步发展区域和/或省级农业食品营销系统;发展市、镇、村农产品营销体系;发展地方纵向、横向网络,促进营销系统的发展;农村和城市地区的发展中市场;促进和加强社区农业食品营销体系、社区和非本地社区企业营销实践和群体集体营销实践;促进增长极和经济走廊以及国内区域和农村发展政策。然而,从研究结果中也可以看出,明显缺乏专门针对农产品中介营销的研究,特别是缺乏从特定的农产品中介营销角度进行的研究,也缺乏对农产品中介营销实践的研究。

However what also emerged from the research findings was the evident lack of research specifically on agri-food mesomarketing, a lack of research conducted taking a specific agri-food mesomarketing perspective in particular and also a lack of research on agri-food mesomarketing practices.","PeriodicalId":346845,"journal":{"name":"Middle East Journal of Agriculture Research","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131655933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Strawberry fruits (Fragaria × ananassa) of the cultivar "Festival" were harvested at 75% maturity on 5 and 9 February in 2017 and 2018 seasons, respectively from private farm in Bader Center, Behera Governorate, Egypt and transported to the postharvest Center, Faculty of Agriculture, Alexandria University, to evaluate the effect of exposure times (10, 20, 30, 40 and 50 min.) of ozone gas on quality attributes of strawberry fruits during storage at 0C for 21 days. Results showed that all ozone treatments of strawberry fruits reduced weight loss and did not show any decay until the end of storage period. Strawberry fruits which exposed to ozone gas for 30 min. was the most effective treatment in maintaining fruit quality, it would reduce weight loss percentage and resulted in fruits with no decay and maintained fruit firmness, TSS, ascorbic acid content, anthocyanins content and total sugars and also gave fruits with good appearance after 21 days of storage at 0C and 95 % RH as compared with the other treatments and untreated control.
在2017年和2018年2月5日和9日,分别从埃及Behera省Bader中心的私人农场收获75%成熟度的草莓(Fragaria × ananassa),并将其运送到亚历山大大学农学院采后中心,以评估臭氧气体暴露时间(10、20、30、40和50分钟)对草莓果实在0℃下储存21天品质属性的影响。结果表明,所有臭氧处理均能减轻草莓果实的重量,并且在贮藏期结束前没有出现任何腐烂现象。在0℃、95%相对湿度条件下,与其他处理和未处理的对照相比,臭氧气体处理30 min可降低草莓果实的失重率,使果实不腐烂,保持果实硬度、TSS、抗坏血酸含量、花青素含量和总糖含量,并使果实在贮藏21 d后具有良好的外观。
