Cold stress is one of the most important environmental stresses for rice especially in temperate and high elevation areas. In present study, the effect of different temperatures, as the main plot, including 25 (control), 10 and 5°C on 12 rice cultivars (including Champa Yasouj, Gerde, Lenjan Askari, Kaamfirouz, Kohsar, Shafagh, Domsiya Mamassani, Dular, Gharib, Hasan saraei, Mosa Tarom and 304)...

Zn deficiency is one of the most important nutritional disorders after macro-nutrients in rice. There are considerable genotypic differences among rice genotypes in response to Zn deficiency. Determination of such differences and introduction of efficient genotypes could lead to significant reduction of fertilizer use for rice production. In this research, some of the most frequently cultivated...

To compare the allelopathic potential of some Guilan province rice cultivars with allelopathically approved IRRI rice cultivars, a factorial experiment was conducted in completely randomized block design with 3 replications on the Experimental Farm of Agricultural College of Guilan University in spring 2005. Two factors including a) seven rice cultivars (traditional cultivars of Hashemi, Ali Ka...

Rice (Oryza sativa L.) is the most important food for half of the world's population. Rice is sensitive to salinity, which is one of the important stresses to limit rice growth and yield in Asia. In order to evaluate the effects of salinity stress on rice vegetative and agronomic characters an experiment was conducted using forty genotypes. The genotypes were tested at 4 salinity levels (0 6 8 ...

Salinity is one of the most extensive environmental stresses and is a limiting factor for the growth and development of crops, such as rice. Then, an experiment based upon completely randomized design with four low levels (0, 7.5, 15, 22.5) and four high of salinity (75, 150, 225 and 300 mM) with control as the first factor and nine cultivars of rice (dollars, Hasan Saraii, Mousa Tarom, Kamfiru...
