The world's population is increasing very rapidly, reducing the cultivable land of rice, decreasing table water, emerging new diseases and pests, climate changes are major issues that must be addressed to researchers develop sustainable crop varieties with resistance biotic abiotic stresses. However, recent scientific discoveries advances particularly in genetics, genomics physiology have opened up opportunities reduce impact these stresses which would been difficult if not impossible as...

Ethylene, the simplest gaseous plant growth regulator (PGR), controls diverse physiological pathways in plants. Under various stress conditions and during different developmental stages, such as root elongation, leaf flower senescence, seed germination, tissue differentiation organ abscission, ethylene biosynthesis is significantly increased. In rice, internal concentration rapidly regulated to a genetically, physiologically morphologically relevant level under stresses. Regulation of...

Ficus deltoidea was used in this study due to its reputation reducing risk of cancer, diabetes and heart diseases. In 13 accessions of F. deltoideawere selected they were divided into two groups, generally named as, female male plants based on leaf sizes the spots present. The signature deltoidea is that plant has black representing while red for leaf. For non enzymatic antioxidants, several methods used, 2,2-diphenyl-1-picrylhydrazil (DPPH) free radical scavenging assay ferric antioxidant...

A study was undertaken to examine the presence of antioxidative activities twovarieties of Labisia pumila; L. pumila var. Alata and L. pumila var. Pumila usingDPPH, FRAP and β-carotene bleaching methods. In addition, ascorbic acid, β-carotene, anthocyanin, total flavonoid phenolic content were also analyzed. eight methods studied, six them showed high antioxidant in L. pumila var. Alata compared that of L. pumila var. Pumila. The results obtained that L. Alata contained higher activities in...

Curcuma longa L. is a rhizome plant often used as traditional medicinal preparations in Southeast Asia. The dried powder commonly known cure-all herbal medicine with wider spectrum of pharmaceutical activities. In spite the widely reported therapeutic applications C. , research on its safety and teratogenic effects zebrafish embryos larvae still limited. Hence, this aimed to assess toxicity extract zebrafish. Using reflux flask, methanol was extracted identification quantification total...

Plant growth promoting rhizobacteria (PGPR) stimulate plant by producing phytohormone which enhances the and physiological activities of host plant. Recently, legume bacteria (Rhizobium spp.) have been considered as a PGPR for well non-legumes potential stimulation. A laboratory experiment was conducted to observe effect Rhizobial inoculation on seed germination, seedling emergence, development lowland rice variety MR219. The under condition using filter paper in Petri dish. design...

The use of periodical water stress and potassium fertilization may enhance rice tolerance to drought improve the crop’s instantaneous efficiency without much yield reduction. This study was conducted assess effects different combined with regimes on growth, yield, leaf gas exchanges biochemical changes in grown pots compare them standard local grower practices. Five treatments including (1) grower’s practice (control, 80CF = 80 kg K2O/ha + control flooding); (2) 120PW15 120 for 15 days; (3)...

Vegetable extracts of nine Malaysian vegetables; Curcuma domestica, Kaempferia galanga, Piper betel, Piper sarmentosum, Polygonum minus, Cosmos caudatus, Centella asiatica, Hydrocotyle bonariensis and Barringtonia racemosa were screened for their antioxidant properties. Total activities leaf or rhizome extract were assayed using different methods; ferric reducing potential assay (FRAP), 1,1- diphenyl-2- picrylhydrazyl free radical scavenging (DPPH) and β-carotene bleaching assay. Another...

The anti-inflammatory, antioxidant and anti-nociceptive properties of six Malaysian medicinal plants, including Carica papaya, Musa acuminata, Oenanthe javanica, Piper sarmentosum, Psophocarpus tetragonolobus and Sauropus androgynus were investigated. anti-inflammatory effects the methanolic plant extracts were evaluated by using Griess assay on nitric oxide inhibitory activity upon IFN-g/LPS stimulated RAW 264.7 cells. property total phenolic content determined DPPH radical scavenging...

Natural products such as herbs, fruits, spices, beverages, vegetables are becoming more popular among scientific community and consumers because of their potential to arrest the effect free radicals in human system. This study determined total antioxidant capacity ten selected species Zingiberaceae (Ginger) used spices for medicinal purposes Southeast Asia.Methanol was extraction solvent, 2,2 - diphenyl-1-picrylhydrazil (DPPH) radical scavenging activity ferric reducing power (FRAP) assays....

Plants from Gynura family was used in this study, namely, procumbens and bicolor . is well known for its various medicinal properties such as antihyperglycaemic, antihyperlipidaemic, antiulcerogenic; meanwhile, G. remains unexploited. Several nonenzymatic antioxidants methods were utilized to study the antioxidant capacity, which include ferric reducing power (FRAP), 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay, total flavonoid content, phenolic ascorbic acid content...

Basal stem rot (BSR), caused by the basidiomycete fungus, Ganoderma boninense, is an economically devastating disease in Malaysia. Our study investigated changes lignin content and composition along with activity expression of phenylpropanoid pathway enzymes genes oil palm root tissues during G. boninense infection. We sampled control (non-inoculated) infected (inoculated) seedlings at seven time points (1, 2, 3, 4, 8, 12 weeks post-inoculation (wpi)) a randomized design. The profiles...

Five levels of water stress cycle (control flooded, control saturated, 5, 10, and 15 days irrigation interval) three potassium fertilization [80 kg, 120 kg 160 dipotassium oxide (K2O) ha−1] were exposed to investigate the influence fertilizer for minimizing effect maximizing productivity rice. Different phyto-physiological parameters as well uptake major nutrient elements [nitrogen (N), phosphorus (P), (K), calcium (Ca), magnesium (Mg), iron (Fe)] examined. It was observed that rice yield,...
