Plants which contain unisexual flowers are subjected to genetic degradation and yield capacity reduction due to the easily cross-pollination. Sponge gourd, one of species of the Cucurbitaceae which is predominantly cross-pollinating, is cultivated to widely use as vegetable in Vietnamese daily meals. The aim of this experiment was to evaluate the growth potential and fruit quality including fruit aroma of sponge gourd inbred lines. Pure line selection has been performed using self-pollinated method, so that sponge gourd lines would be recovered with high yielding and aroma and thereby recommended for further crop system in Thua Thien Hue province, Central Vietnam. The experiment was conducted in a randomized complete block design (RCBD) with three replications during the winter-spring season in 2017. Agronomical data were observed and analyzed on seven inbred lines (1-MN1, 1-MN2, 5-MN1, 7-MN1, 13-MN2, 15-MN1 and 15-MN2) derived from B29 accession (GBVN006904). The results indicated that inbred lines 13-MN2, 1-MN2 and 15-MN1 attained more highly fruit weight and yield compared to the others. Four inbred lines consisting of 5-MN1, 7-MN1, 15-MN1 and 15-MN2 still retained the light aroma after boiling. The inbred lines 1-MN2, 7-MN1, 13-MN2 and 15MN1 are considered for appropriately using in breeding program of new luffa.
单性花植物由于容易异花授粉,容易发生遗传退化和产量下降。海绵葫芦是葫芦科的一种,主要是异花授粉,在越南的日常饮食中被广泛种植作为蔬菜。本试验旨在评价海绵葫芦自交系的生长势和果实品质,包括果实香气。采用自花授粉的方法进行了纯选系,使海绵葫芦品系恢复高产和芳香,从而推荐用于越南中部顺化省的进一步作物系统。试验采用随机完全区组设计(RCBD),于2017年冬春季节进行3个重复。对来自B29品种(GBVN006904)的7个自交系(1-MN1、1-MN2、5-MN1、7-MN1、13-MN2、15-MN1和15-MN2)进行了农艺分析。结果表明,自交系13-MN2、1-MN2和15-MN1的单倍率和单倍率较高。5-MN1、7-MN1、15-MN1和15-MN2自交系煮沸后仍保持淡香气。自交系1-MN2、7-MN1、13-MN2和15MN1可用于新丝瓜选育。

Adapting and restricting salinity intrusion in Vietnam is being concerned by more researchers as well as the local authorities. This study aimed to use remote sensing and geographic information system (GIS) technology for mapping paddy areas and salinity intrusion in spring crop 2015 at Phu Vang district, thereby helping precondition for assessing and monitoring changes in salinity intrusion to serve for salinization management in study area. Based on acquisition imagery, land use map and normalized difference vegetation index (NDVI) were extracted to interpolate the salinity of area by combining the laboratory analysis of collected soil samples from the field. The result showed that there were 1,067.107 ha of salinity land area accounting for 10.04% of the rice land in Phu Vang district, where the moderate salinity level was 180.67 ha and low salinity level was 866.431 ha. The salinity rice land was mainly distributed in Vinh Ha commune, Phu An commune and Phu Dien commune. The salinity in this area ranged from 0.4 mS/cm to 1.41 mS/cm and the moderate salinity was approximately 0.9 mS/cm. Besides, this research also showed that the salinity (electrical conductivity) and the development of vegetation (NDVI) were closely related with each other up to 61.4%.

Terapon jarbua was collected from Tam Giang-Cau Hai lagoon systems and then their reproductive performances were investigated. Total 342 species were caught by otter trawlers and different fishing gears in marine and Tam Giang-Cau Hai lagoon systems on certain days of each month during period from September 2015 to August 2016 at fishing port. The determination of age was based on composition of the fish: ear, scaly, spine, gill cover and spine and the ovarian histology template. The gonads after being fixed with Bouins solution were cleansed, cut, dyed and put on the observation microscope. Results showed that the sex of Terapon jarbua was nearly clarified at the approximately 1+ age group and participated in reproduction process in the first time at the 1+ age group. The batch and relative fecundity of Terapon jarbua were high. The batch fecundity of Terapon jarbua varied from 239,029 to 420,400 eggs. The relative fecundity capacity fluctuated from 945 to 1,013 of eggs per gram of fish and the mean value by 981 eggs per gram of fish. The spawning season of fish occurred from March to May annually.

Infection of Escherichia coli in piglets is identified as one of major problems in pig husbandry. Data were collected from different experiments conducted at farm levels and results showed that the percentage of piglets infected with E. coli was very high. E. coli infected healthy piglets were up to 48.9% and E. coli infected diarrhea piglets accounted for 88.3%. Using Betel Bokashi and antibiotics in treatment brings about different results. Out of 48 infected piglets, 15 piglets were selected for three groups treatment with five each group. Results showed that 92.3% diarrhea piglets treated with Betel Bokashi recovered in 3.85 d, while 100% and 88.23% treated with antibiotics were cured in 4 d and 4.01 d, respectively. Post-treatment piglets in group 3 grew up faster than group 1 and group 2, with gains 231, 218 and 212 g, respectively.
仔猪大肠杆菌感染是养猪业面临的主要问题之一。从农场水平进行的不同实验中收集数据,结果表明仔猪感染大肠杆菌的百分比非常高。大肠杆菌感染健康仔猪占48.9%,大肠杆菌感染腹泻仔猪占88.3%。槟榔与抗生素治疗效果不同。48头感染仔猪中,选取15头仔猪分成3组,每组5头。结果表明,治疗后腹泻仔猪的治愈率为92.3% (3.85 d),抗生素治疗后腹泻仔猪治愈率为100% (4 d),治愈率为88.23% (4.01 d)。处理后3组仔猪的生长速度快于1组和2组,增重分别为231、218和212 g。

Adult rice field eels with 125.52 ± 27.99 g body weight corresponding to 44.79 ± 5.93 cm in length were maturity cultured in a 5 m cement tank without mud for three months with density 30 eels/m. Eel broodstocks were fed with three types of food including: sea fish (T1), commercial pellet food (T2) and mixed food—50% sea fish and 50% commercial pellet food (T3). Result showed that the maximum gonadosomatic index (GSI) of female eels fed by sea fish (2.89% ± 0.67%) was higher than both commercial pellet food (1.62% ± 0.62%) and mixed food (2.03% ± 0.82%) (P < 0.05), while, GSI of male eels was 1.27% ± 0.31%, 0.68% ± 0.23% and 1.14% ± 0.41% (P > 0.05). Maturity rate of female fed by sea fish (88.91% ± 9.64%) was higher than commercial pellet food (61.12% ± 9.64%) (P < 0.05). The maturity rate of male eels was rather low and there was not significantly different among treatments (P > 0.05). Then. the eels were induced for spawning with two kinds of hormones, including T1: human chorionic ganadotropin (HCG) at 1,500 IU/kg, T2: luteinzing hormone-releasing hormone (LHRH-a) at 150 μg/kg and domperidon 10 mg/kg, and T3: control without hormone. The results of spawning induction methods showed that the reproduction rate of female eels induced by LHRH-a and HCG hormones were higher than that by natural reproduction method (P < 0.05). Others, the survival rate of fry eels after 5 d using natural reproduction method (92.65% ± 2.54%) was higher than both using LHRH-a (67.77% ± 1.91%) and HCG (68.65% ± 1.23%) hormones (P < 0.05). The average diameter of eggs was 3.40-3.41 mm and the length of newly hatched eels was 1.72 ± 0.19 cm.
将体重为125.52±27.99 g、体长为44.79±5.93 cm的稻田鳗鲡成体在无泥的5 m水泥池中成熟培养3个月,培养密度为30条/m。用海鱼(T1)、商业颗粒饲料(T2)和混合饲料(50%海鱼和50%商业颗粒饲料(T3))饲喂鳗鲡幼鱼。结果表明,以海鱼为食的雌鳗的最大促性腺指数(GSI)为2.89%±0.67%,高于商业颗粒饲料(1.62%±0.62%)和混合饲料(2.03%±0.82%)(P < 0.05),而雄鳗的GSI分别为1.27%±0.31%、0.68%±0.23%和1.14%±0.41% (P > 0.05)。以海鱼为食的雌鱼成熟率(88.91%±9.64%)高于市售颗粒饲料(61.12%±9.64%)(P < 0.05)。雄鳗的成熟率较低,各处理间差异不显著(P > 0.05)。然后。分别用1,500 IU/kg人绒毛膜促性腺激素(HCG)、150 μg/kg促黄体生成素释放激素(LHRH-a)和10 mg/kg冬冬两种激素诱导鳗鲡产卵,T3为不加激素对照。诱导产卵法结果表明,LHRH-a和HCG激素诱导的雌鳗繁殖率高于自然繁殖法(P < 0.05)。自然繁殖法5 d后鱼苗成活率(92.65%±2.54%)高于LHRH-a(67.77%±1.91%)和HCG(68.65%±1.23%)激素组(P < 0.05)。卵的平均直径为3.40 ~ 3.41 mm,新孵鳗鱼的平均长度为1.72±0.19 cm。

This study used 10 rice lines and varieties, including the salt tolerant variety (Pokkali) and salt susceptible variety (IR29) as control. Experiment for screening rice salinity tolerance at seedling stage was conducted in hydroponic system using five different salinity concentrations (0, 4, 6, 8 and 10 dS/m). Flowering stage was evaluated at the salinity level of 8 dS/m. The experiment was designed in randomized completely block (RCBD) with three replications for each line/variety under non-saline and saline condition. The results showed that the growth of rice lines/varieties was retarded severely with increasing salinity levels, and almost all of leaves were drying and dead completely (score 7 and 9). Plants of IR29 and OM7347 were dead at the electrical conductivity (EC) = 10 dS/m, whereas Pokkali (the tolerant variety) and IR93350 were evaluated at score 5. Salinity stress caused the reduction of overall vigor of rice lines/varieties especially in the pollen germination, fertilization and grain yield. Rice lines/varieties were classified to salinity tolerance levels as following: IR5040, IR93350, IR86385-8D-1-2-B and Pokkali (tolerant); OM8104, IR93340 and IR93343 (moderate susceptible); OM7347, IR87832-303-1-B and IR29 (susceptible).
本研究以耐盐品种Pokkali和盐敏感品种IR29为对照,选用10个水稻品系和品种。在0、4、6、8和10 dS/m 5个不同盐度浓度的水培系统中进行了水稻苗期耐盐性筛选试验。在8 dS/m的盐度水平下,对花期进行了评价。试验采用随机完全区组(RCBD)设计,每个品系/品种3个重复,分别在不含盐和含盐条件下进行。结果表明,随着盐度的升高,水稻品系/品种的生长严重受阻,叶片几乎全部干燥死亡(评分7和9)。IR29和OM7347在电导率(EC)为10 dS/m时死亡,而耐盐品种Pokkali和IR93350在电导率(EC)为5分时死亡。盐胁迫导致水稻品系/品种整体活力下降,尤其是花粉萌发、施肥和产量下降。水稻品系/品种的耐盐性等级如下:IR5040、IR93350、IR86385-8D-1-2-B和Pokkali(耐盐);OM8104、IR93340和IR93343(中度易感);OM7347, IR87832-303-1-B和IR29(易感)。

Shishibishio, a Japanese traditional seasoning, is made from fermented meat. The study aimed to evaluate the effect of neutrase 0.5 L alone or flavourzyme 500 L + neutrase 0.5 L on the acceleration of fermentation period and the improvement of nutritional value and sensory acceptance of the final product. The fermentation mixtures (moromi) were prepared by mixing ground pork with salt at one of three concentrations (15%, 20% or 25%), koji (rice fermented with Aspergillus oryzae) and pepper. To accelerate the fermentation of moromi, all treatments were added with neutrase at the begining, then adding with or without flavourzyme after one month. The results showed that neutrase or neutrase + flavourzyme mixture accelerated hydrolysis of meat protein during the fermentation of moromi. Yield, protein recovery, total nitrogen and free amino acid in shishibishio treated with enzymes were significantly greater (P < 0.05) than that of control, especially at 15% salt. The treatment treated with neutrase + flavourzyme was significantly increased (P < 0.05) in free amino acid as compared with treatment with neutrase alone, resulting a better sensory taste and smell, which was mostly accepted. Almost the shishibishio obtained after six fermentative months was acceptable seasonings having a good taste and no unpleasant smell.
调味料是一种日本传统调味品,由发酵过的肉制成。本研究旨在评价单独添加0.5 L中和酶或添加500 L风味酶+ 0.5 L中和酶对加速发酵周期、提高最终产品营养价值和感官接受度的影响。发酵混合物(moromi)是用三种浓度(15%、20%或25%)中的一种盐、曲(用米曲霉发酵的大米)和胡椒混合制成的。为了加速森米的发酵,所有处理在开始时都添加了中和酶,然后在一个月后添加或不添加风味酶。结果表明,在发酵过程中,中和酶或中和酶+风味酶的混合物加速了肉蛋白的水解。施酶处理的水蛭产量、蛋白质回收率、总氮和游离氨基酸均显著高于对照(P < 0.05),其中15%盐处理效果最显著。中和酶+风味酶处理与单独中和酶处理相比,游离氨基酸含量显著增加(P < 0.05),感官味觉和嗅觉更好,被普遍接受。经过6个月的发酵,得到的石料几乎是可以接受的调味料,味道好,没有难闻的气味。

The aim of the study was to evaluate the drought tolerance, agro-morphological characteristics and yield of 10 rice varieties collected from different locations. In experiment one, drought tolerance of rice varieties under artificial drought condition in the greenhouse was assessed through root and leaf characteristics. In experiment two, the growth and yield of rice varieties in the rainfed rice field was estimated. The results showed that drought has affected the root characteristics, leaf rolling and leaf drying of these varieties. In rainfed rice field of Thua Thien Hue and Quang Nam province, summer-autumn 2016 and winter-spring 2016-2017 crop season, these rice varieties grew and developed well. The growth time was 90-119 d in summer-autumn crop season, while in winter-spring crop season was 107-131 d. The yield of these rice varieties ranged from 37.02 quintals/ha to 56.33 quintals/ha and from 42.33 quintals/ha to 66.60 quintals/ha, respectively. Some rice varieties with high yields in both two crop seasons were OM4900, GSR38, IR93340 and OM7347. It is sugessted to conduct production experiment on a large area in rainfed field for these four varieties to evaluate them objectively and early put them into structure of rice varieties in Central Vietnam.
本研究旨在评价不同产地10个水稻品种的耐旱性、农业形态特征和产量。试验一通过根系和叶片性状对温室人工干旱条件下水稻品种的耐旱性进行评价。试验二对旱作稻田的水稻品种生长和产量进行了估计。结果表明,干旱影响了这些品种的根系特征、卷叶和叶片干燥。2016年夏秋季和2016-2017年冬春季,在顺化顺化和广南省的雨养稻田,这些水稻品种生长发育良好。夏秋作物生长期为90 ~ 119 d,冬春作物生长期为107 ~ 131 d,产量分别为37.02 ~ 56.33和42.33 ~ 66.60公担/ha。两个作物季均高产的水稻品种有OM4900、GSR38、IR93340和OM7347。建议对这4个品种进行大面积旱地生产试验,客观评价,尽早纳入越南中部水稻品种结构。
