Starting in 2018, VJAS is set to launch a full English version of VJAS and publish quarterly both online and in print with the ISSN 2588 – 1299. Each issue will contain 8-10 articles, with each article being approximately 5000-8000 words. All submissions will be independently refereed by editorial board members and will undergo rigorous peer-review following international standards from at least two assigned peer reviewers (including one Vietnamese reviewer and one foreign reviewer) who come from universities, institutes, and relevant administrative agencies in Vietnam and from other countries around the world. The aim of VJAS is to be indexed in ISI/Scopus lists within four to six years from its first published issue (August 2018).

Identification of Optimal Culture Conditions for Mycelial Growth and Cultivation of Monkey Head Mushrooms (Hericium erinaceus (Bull.: fr.) Pers)

Identification of Optimal Culture Conditions for Mycelial Growth and Cultivation of Monkey Head Mushrooms

by Bich Thuy Thi Nguyen, Nghien Xuan Ngo, Ve Van Le, Luyen Thi Nguyen, Anh Dong Tran, Lam Hai Thi Nguyen
Published: Oct 19, 2018
Abstract: Monkey head mushrooms (Hericium erinaceus (Bull.: Fr.) Pers) have been broadly cultivated and widely consumed as traditional medicinal herbs as well as functional food in the Orient for several hundred years of history. The identification of optimal culture conditions for mycelium growth and fruiting body formation is one of the most important steps in cultivation of mushroom. The aim of this study was to investigate the optimal culture conditions including pH level, temperature, media and [...]Read more

The Influence of Bulb Storage Regimes on the Growth and Flowering of Hippeastrum (Hippeastrum hybridum Hort.)

The Influence of Bulb Storage Regimes on the Growth and Flowering of Hippeastrum (Hippeastrum hybridum Hort.)

by Huyen Trang Thi Pham, Nam Van Dinh, Thanh Nga Thi Trinh, Thu Ha Thi Phung, Thuy Hanh Thi Nguyen, Hoa Hanh Nguyen
Published: Oct 22, 2018
Abstract: Hippeastrum hybridum cultivar ‘Cam Tu’ bulbs were subjected to ten different treatment regimens to evaluate the effect of temperature (4°C or 25°C), duration (4, 6, or 8 weeks), and wrapping materials (coir fiber or newspaper) on their growth and flowering. The data revealed that the storage treatments had significant effects on several growth and flowering characteristics of H. hybridum cv. ‘Cam Tu’. In terms of vegetative characteristics, bulbs stored at 4°C with coir fiber [...]Read more

Effects of Osmotic Stress Induced by Peg and NaCl on the Germination and Early Growth of Mung Bean

Effects of Osmotic Stress Induced by Peg and NaCl on the Germination and Early Growth of Mung Bean

by Thang Ngoc Vu, Khuynh The Bui, Gioi Huy Dong, Tuan Anh Tran, Tuyet Cham Thi Le, Chinh Dinh Vu
Published: Oct 22, 2018
Abstract: This study was performed to evaluate the effects of osmotic stress (measured by different water potentials) induced by Polyethylene Glycol 6000 (PEG) and NaCl solutions at the germination stage of five mung bean varieties (DX11, DX208, DX14, DX17, and DX22). Five water potentials: 0 (control), -0.15, -0.49, -1.03, and -1.76 Mpa were used as treatments in this study. The germination rates, root and shoot lengths, root and shoot fresh weights, and dry weights of the plants were measured. The [...]Read more

Nitrogen-Use Efficiency Evaluation and Genome Survey of Vietnamese Rice Landraces (Oryza sativa L.)

Nitrogen-Use Efficiency Evaluation and Genome Survey of Vietnamese Rice Landraces (Oryza sativa L.)

by Hanh Thi Thuy Nguyen, Thuy Linh Mai Dinh, Trung Quoc Nguyen, Cuong Van Pham
Published: Oct 22, 2018
Abstract: The overuse of fertilizers can result in many adverse effects such as decreasing fertilizer use efficiency of plants, wasting resources, increasing farming costs, and polluting our environment. Local rice landraces including indigenous and local rice varieties, may contain considerable genetic diversity that can serve as sources of germplasm for genetic improvements of nutrient use efficiency, yield, resistance to pests and pathogens, and important agronomic traits. Increasing the fertilizer [...]Read more

Establishment of Reciprocal Micrografting of Tomato (Solanum lycopersicum L.) and Eggplant (Solanum melongena L.)

Establishment of Reciprocal Micrografting of Tomato and Eggplant

by Son Truong Dinh, Tham Thi Tran
Published: Oct 22, 2018
Abstract: Micrografting can be used as a key tool to investigate gene-function, long-distance signal transduction, or metabolite movement in different developmental and physiological stages. In plant production, plant grafting can be applied to improve productivity and/or increase the tolerance of plants to stresses. Here, we describe a simple and high efficiency protocol for reciprocal micrografting of tomato (Solanum lycopersicum L.) and eggplant (Solanum melongena L.). Tomato and eggplant seeds can be [...]Read more

Studies on the Biological Characteristics of the Bt116 Lingzhi Mushroom Strain (Tomophagus sp.) Collected in Hanoi

Studies on the Biological Characteristics of the Bt116 Lingzhi Mushroom Strain Collected in H

by Anh Dong Tran, Minh Nhat Ngo Nguyen, Nghien Xuan Ngo, Bich Thuy Thi Nguyen, Luyen Thi Nguyen, Canh Xuan Nguyen
Published: Oct 22, 2018
Abstract: In this study, an unknown mushroom species collected on rotting trunks of Ficus elastica in the Hanoi Botanical Garden was investigated. It was designated as Bt116. Based on the observed morphological characteristics, such as irregularly semi-circular, slightly yellow pileus; very soft, homogeneous, spongy, creamy white context; short and not clear stipes; and basidiospores typical of ganoderma mushrooms, etc., we hypothesized that Bt116 belongs to the Tomophagus Murr. mushroom genus. Some [...]Read more

Polymorphism Candidate Genes of Lien Minh Chickens

Polymorphism Candidate Genes of Lien Minh Chickens

by Binh Nguyen Thi Tran, Duc Huu Nguyen, Quy Duc Vu, Giang Thu Pham, Linh Manh Nguyen, Ngoc Thuy Thi Dinh, Dieu Thuy Thi Nguyen
Published: Oct 22, 2018
Abstract: Lien Minh chicken is an indigenous breed with several favorable properties, such as high productivity and good meat quality, and is associated with the economic development of the people in the Lien Minh village, Cat Hai, Hai Phong. The objective of the current research was to investigate the single nucleotide polymorphisms (SNPs) of candidate genes, which might be associated with broodiness and egg production traits. Ninety Lien Minh chicken individuals were genotyped for five SNPs of chicken [...]Read more

Effects of Caffeine on In Vitro Fertilization of Pig Follicular Oocytes

Effects of Caffeine on In Vitro Fertilization of Pig Follicular Oocytes

by Thuong Thi Nguyen, Dat Tien Nguyen, Hanh Van Nguyen, Duc Huu Nguyen, Linh Viet Nguyen
Published: Oct 22, 2018
Abstract: In the present study, experiments were conducted to assess the effects of caffeine on in vitro fertilization of pig follicular oocytes. Cumulus-oocyte complexes (COCs) were collected from porcine ovaries from slaughterhouses, cultured in in vitro maturation medium 1 (IVM1) at 38.5oC for 20-22 hours and then in in vitro maturation medium 2 (IVM2) for the next 24 hours. Only the oocytes with expanded cumulus cells were selected for in vitro fertilization. Boar frozen semen was used for the [...]Read more
