Abstract Rice is the first food crop for which complete genome sequence is available. This offers an unprecedented opportunity to identify and functionally characterize the genes and biochemical pathways that are responsible fo...

Rice (Oryza sative L.) is the main food crop in Asia and the staple food of the majority of the population in many regions of the world. The population pressure in rice-consuming countries demands that more attention be directed towards new approaches to sustainable rice produc‐ tion. Improvement of both crop quality and yield is an urgent task [1]. Optimally, rice yield improvement must be sou...

The rice leaf folder, Cnaphalocrocis medinalis (Guenée), is one of the most destructive rice pests in Asian countries. Rice varieties resistant to the rice leaf folder are generally characterized by high silicon content. In this study, silicon amendment, at 0.16 and 0.32 g Si/kg soil, enhanced resistance of a susceptible rice variety to the rice leaf folder. Silicon addition to rice plants at b...

A pot trial was conducted with 52 rice cultivars of different types collected from different origins. The results showed that there were great differences in Cd concentrations in straw, brown rice and grain chaff among the rice cultivars grown in a soil containing a Cd concentration of 100 mg kg−1; the Cd concentrations in brown rice ranged from 0.22 to 2.86 mg kg−1. The great genotypic differe...

Plastic mulch increased minimum temperature of soil, accelerated plant height,early growth, early yield, and bring satisfactory weed control without anyapplication of herbicides. This experiment was laid out on three-factorialRandomized Complete Block Design with three replications during 2008-2010 atthe National Rice Research Institute, Rasht, Iran using three kinds of mulches(Transparent and ...

Defatted rice bran was treated with subcritical water between 120 and 240°C. The extraction temperature af fected the total carbohydrate and protein contents of the extracts. In the tested temperature range, the total carbohydrate and protein contents were the highest at 180°C and 210°C. The DPPH radical scavenging activity of the extracts increased with increasing extraction temperature up to ...

Black rice is an heirloom rice landrace mostly grown in China, Korea, Japan, Thailand, Philippines and India [1]. This rice is highly rated in the market because of its huge nutritional value [2]. The main peculiarity of black rice is its anthocyanin which is both fat and water soluble. Earlier, it was believed that this rice enhance the longevity of life hence this rice is also known as long l...

This study aimed to explore the ecological adaptability and the possibility of growing rice with floating bed on the dilute biogas slurry. The results of the experiments show that the growth stage, rice plant height, and rice yield and quality were significantly affected by multiple dilutions; rice plants cultivated with 45 multiple dilutions had better ecological adaptability than others. In t...
