abstract in order to investigate the freezing tolerance of field grown fennel (fueniculum vulgare mill) under controlled conditions, a factorial experiment based on completely randomized design was conducted with three replications in agricultural college, ferdowsi university of mashhad in 2004. treatments were two fennel ecotypes (khorasan and kerman), two planting dates (oct 8th and 29th ) an...

abstract the aim of this experiment was the study of freezing tolerance of bellis perennis under controlled conditions and were arranged in a completely randomized design with three replications. plants after sowing and grow in the bed, at the middle of autumn (after hardening in natural conditions), in the 7-8 leaf stage put on the thermogradiant freezer with the 12 freezing temperatures (0,-2...

to evaluate the freezing tolerance in sugar beet (beta vulgaris l.), seven cultivars (suprema, jolge, monotunno, giada, pp8, sbsi1, palma) were exposed to the 10 temperatures (0, -2, -4, -6, -8, -10, -12, -14, -16 and -18˚c) .the study carried out as a factorial arrangement of treatments based on randomized completely design with three replications at college of agriculture, ferdowsi university...

freezing stress affected some vital processes of plant, and causing disturbance on the plant growth. in order to study the effect of low temperatures on freezing tolerance of chickpea (cicer arietinum l.) a factorial experiment with 4 replications carried out using 3 chickpea genotypes (mcc496، mcc763 and mcc798) and 7 freezing temperatures (-4, -6, -8, -10, -12, -14 and -160c). explants were c...

in order to investigate the physiological and morphological traits of seven autumn sugar beet (beta vulgaris l.) cultivars (jolge, palma, giada, monotunno, sbsi1, suprema and pp8), under  freezing stress, a study was carried out as a factorial experiment (7×10) based on randomized complete block design with three replications in college of agriculture of ferdowsi university of mashhad. the plan...

Lack of chickpea cultivars tolerant to extreme freezing is a limiting factor for autumn planting of this crop in cold areas. In this study, 58 Kabuli-type chickpea genotypes and a control (an international sensitive genotype) were planted in pots and first exposed to -10°C and then to -15°C after being acclimated in natural conditions. No destructive effect of -10°C was observed in plants. So, ...

nowadays, wind erosion and dust have become environmental problems, not only in desertareas, but throughout the entire country, which have imposed many costs on the country budget.combating wind erosion in many deserts using adapted plants and oil mulch has 40 years history.but the widespread use of petroleum mulches in addition to environmental problems is noteconomically justified due to the ...
