Arsenic (As) toxicity can be a hazardous threat to sustainable agriculture and human health. In order to investigate the effect of As (0, 25 and 50 µM) on growth, physiological traits and expression of As and Fe transporters in Tarom hashemi and Fajr rice cultivars, a factorial experiment based on a completely randomized design was conducted in 2020 in greenhouse conditions at Ayatollah Amoli B...

Background and purpose: Rice (Oryzasativa L.) is one the most important staple food in the world. There is an increasing interest for pigmented varieties, due to their antioxidant properties. In this research, the antioxidant activities in different parts of three varieties of rice were studied. Materials and methods: White rice, brown rice, husk, and bran of Fajr, Hashemi and KB13 were extrac...

this thesis basically deals with the well-known notion of the bear-invariant of groups, which is the generalization of the schur multiplier of groups. in chapter two, section 2.1, we present an explicit formula for the bear-invariant of a direct product of cyclic groups with respect to nc, c>1. also in section 2.2, we caculate the baer-invatiant of a nilpotent product of cyclic groups wuth resp...

Ready-to-eat or canned products have an important place in urban life style. Rice is consumed by half of world population. Problems related to production of canned rice are the coherences of rice kernel, retrogradation of rice starch and physico-chemical changes of rice during storage. Main factors affecting physico-chemical properties of canned rice are rice cultivar, amylose and amylopectin c...

In order to physiological and biochemical evaluation of seventh generation of rice mutant tolerant lines under salinity stress, an experiment was carried out as split plot arranged in a Completely Randomized Design with four replications. Main factor of experiment includes three levels of salt stress (0, 45, 75 mmol/l) and sub factor include 5 local rice mutant lines contain Tarom Hashemi 1, Ta...
