sod culture is one of the important methods in establishing and repairing of turf grass, especially in sport fields. nowadays, a mixture of sand and peat are commonly used in sod production in iran. because peat media is expensive, it seems necessary to find an alternative medium. rice hull, tea waste and leaf compost as economical organic material that are available in huge loads in north of i...

The use of seeds with high physiological quality allows rapid growth and establishment seedlings in the field to be obtained. Therefore, accuracy information obtained during determination is great importance. objective was generalized linear models, investigating which link function (Probit, Logit Complementary log-log) suitable predict T50 uniformity germination soybean corn seeds. To perform ...

the main objective of this study was using of canonical correlation analysis (cca) to find relations between 15 different variables of seed emergence and seedling growth related characteristics of seven important crop that were classified in three groups. the studied groups of variables were included physical characteristics (seed weight, seed length, seed density, water absorption and water co...

this study evaluated direct drilling planters used for wheat cultivation in khorasan-e razavi province. a randomized complete block design with three replications was used. the treatments were direct drilling of wheat plants into wheat residue using the following direct planters: (1) sfoggia (13-25), (2) baldan (spd3000), (3) tondar (spd 2500), (4) semeato (shm 11/13). the parameters measured w...

in order to evaluation the effect of drought stress on germination indices and early seedling growth of medicinal herb dill (anethum graveolens l), an experiment was conducted in the agricultural laboratory of urmia payam noor university in 2015 as a randomized complete block design with four replications. treatments were five levels of drought stress (0, -1, -2, -3 and -4 bar induced by polyet...

Seed priming has been suggested to improve germination performance under temperature or water stress. The objective of this study was to develop an optimal osmopriming protocol for spinach (Spinacia oleracea L. cv. Bloomsdale) seeds and examine its effect on the germination performance at suboptimal and supraoptimal temperatures, and under water stress. Standard germination tests at optimal ger...

1 Faculty member,Agricultural and Natural Resources Research Center of Yazd, Yazd, Iran ABSTRACT. Seed germination and seedling growth are critical stages in the life cycle of a plant, especially under adverse abiotic stresses. Seed germination negatively affected by stress conditions. Seed priming techniques have been used to increase germination characteristics and improve germination uniform...

The objective of the present study was to describe the trend of germination characteristics for a variety of canola ‘Okapi’ at different pre-soaking durations. For this purpose, seeds were placed in 250 ml of distilled water for 0 to 12h with intervals of 2h at room temperature. Each sample of seed was placed in Petri-dishes and germinated at the temperature of 25°C. Fitting logistic function o...

Many endangered plants such as Eryngium viviparum (Apiaceae) present a poor germination rate. This fact could be due to intrinsic and extrinsic seed variability influencing germination and dormancy of seeds. The objective of this study is to better understand the physiological mechanism of seed latency and, through artificial intelligence models, to determine the factors that stimulate germinat...
