Based on image processing technology, the detection, classification and feature extraction for plant grain shape are performed in this paper. Taking rice grain as an example, the shape detection and description method of similar round object are studied firstly. Then a grain shape description method based on 8 feature points of rice grain boundary is proposed. Aiming at rice seed detection, a s...

A simple extraction method was developed for obtaining the white tip nematode, Aphelenchoides besseyi Christie, from single seeds of rice, Oryza sativa. The method was as follows: Individual rice seeds were split longitudinally and then transferred into single pipet tips. Tips containing a split seed were then singly placed upright in glass vials with water to extract the nematodes. This method...

The production of conidia of entomopathogenic Beauveria bassiana by solid-state fermentation was studied for the development of a biocontrol agent against aphid Myzus persicae. The optimal conditions for conidia production on polished white rice were 40% moisture content, 25℃ culture temperature, 2-day-old seeding culture grown in 3% corn meal, 2% rice bran, 2% corn steep powder medium, initial...

line no. 4 was selected from local champ a rice of lord egan, based on pure line selection method, during 1992 to 1995. the mean yield of this line was 6342 and 6829 kgha-l in two regions of lord egan in 1996 to 1997. the yield of this line was 700-1500 kgha-l more than that of lord egan local rice. line 4 is more early maturing than the local rice with better marketability and quality. amylase...

Rice is a staple carbohydrate throughout much of the world. Previous work indicated that resistant starch (RS) content of rice consumed in India varied with rice variety and cooking method. This study quantified RS in 4 white rice varieties (jasmine, long grain, medium grain, and short grain) cooked in three manners (oven baked, conventional rice cooker, and pressure cooker), and analyzed for R...

Rice grains are the main crops consumed by more than half of world’s population. White rice contains carbohydrates, while pigmented varieties nutritious, with bioactive compounds that can potentially prevent pro-inflammatory diseases like diabetes and hypertension. Broken is produced in large quantities as a cheap by-product milling; however, its nutraceutical contents have not been identified....

The efficacy studies conducted for six months revealed a significant increase in Haemoglobin and serum ferritin and a significant decrease in total iron binding capacity in the subjects consumed iron-fortified rice, but more so in the subjects consumed rice fortified with iron along with either vitamin A or beta-carotene. Likewise, the serum retinol was significantly increased in children recei...

An isolation and purification procedure is described for AAL-toxin, a secondary metabolite produced by Alternaria alternata. The method involves growth of the fungus on rice media, extraction with chloroform followed by methanol: water from fungus-infested rice, and purification of the aqueous layer that contains AAL-toxin by using chromatography methods. The AAL-toxin was of type A, and white ...

Rice (Oryza sativa L) is an important source of essential elements but also can contain high As concentrations, which may be consumed and causes health effects. This work aimed to contribute the lack information quantifying total arsenic (tAs) in 31 domestic rice (white rice, n=19; brown n=7; parboiled n=5) different brands purchased Peruvian markets. The tAs content was conducted by ICP-MS. co...
