Thix study aims to evaluate and compare the effects of two herbs: IAS-1 herb extract prepared from stem and leaf powders of Andrographis Paniculata (Burm.f.) Nees (37.2%), Tinospora Crispa (L.) Miers (40.1%) and Ginger (Zingiber officinale Roscoe) (21.8%) and IAS-2 herb extract made up from stem and leaf powders of Pouzolzia zeylanica (L.) Benn (21.6%)

The objective was to determine the effects of ascorbic acid (AA), trichostatin A (TSA), and their combined treatment (TA) on reprogramming and development of cloned porcine embryos. Embryos treated with AA (50 and 100 mg/mL) had a higher blastocyst rate than controls (49.6% and 44.0% vs 30.7%, P < .05).

The study aims at determining the pathogen causing ratoon stunt disease (RSD) via morphological, biochemical and molecular properties, and suggesting the appropriate management especially in seed multiplication.

In SC medium plus nalidixic acid at 10µg/ml, the colony diameters obtained 0.19 mm (varied from 0.09 mm to 0.30 mm) withouth pigment or with lightly white colour.Catalase reaction was positive but negative oxydase and red methyl reactions

Phytate, myo-inositol 1,2,3,4,5,6-hexakisphosphate, is the primary source of inositol and the major storage form phosphorus in agricultural feedstuffs, such as cereals, legumes, and oilseeds. Phytase, myo-inositol hexakisphosphate hydrolase (EC 3.1.3.8 for 3-phytase and 3.1.8.26 for 6-phytase), catalyzes the hydrolysis of phytate into myo-inositol and inorganic phosphates

Morphological characteristics of 20 black pepper cultivars commonly grown in principal production areas representing for three agro-ecological regions in the Southern provinces (Dong Nai, Ba Ria-Vung Tau, Dak Nong, Gia Lai and Phu Yen provinces) were recorded based on descriptors for black pepper developed by the International Plant Genetic Resources Institute

The most important research findings relate to 1) the importance of vertical integration under contract farming from in agriculture in general and shrimp production in particular; 2) the shrimp production in the world, especially in Vietnam; 3) the flow of shrimp in MRD and farmers production affectivity; 4) the vertical integration of farmers under contract farming form with a providing of social and technical barriers that affect ability of farmers to integrate in the shrimp value chain;

The thesis “Assessment of the genetic diversity of black pepper cultivars (Piper nigrum L.) commonly planted in three main cultivated areas of the Southern provinces based on morphological characteristics” was conducted from May 2008 to August 2009
