Direct seeding method of rice planting offers several advantages. However, all rice cultivars are not suitable for this practice. In this report forty-three high yield rice varieties and an anoxia/hypoxia tolerant control land race were studied to verify their suitability to establish seedling under anaerobic conditions. The study was conducted in controlled field conditions. The percentage of ...

There has been some concern about using small seeds that may result from seed position on the ear or poor growing conditions for seeding hybrid maize. This study was designed to investigate the effect of seeding three commercial maize crosses (Single Cross 2010, Three-Way Cross 310 and Three-Way Cross 321) with three seed sizes (large, medium and small) under seven salinity levels of irrigation...

In this work, the effects of boric acid pretreatment on the seed germination, seedling growth (coleoptile percentage, radicle length, coleoptile length, radicle number and fresh weight) and leaf anatomy of barley under saline conditions were studied. In parallel with concentration increase, salt stress inhibited the germination and seedling growth of barley seeds. Boric acid application allevia...

soil and water sources salinity are important constrains which threat the sustainable agriculture production in iran. in order to evaluate the effect of different antioxidants and salinity levels on germination and seedling properties of two medicinal species (cnicus benedictus l.), and (cichorium intybus l.), an experiment was conducted using a factorial based on completely randomized design w...

in order to evaluate the morphological changes of rice seedlings (variety of neda and fajr) under salinity management in 1394 was conducted in islamic azad university, ayatollah amoli. this factorial experiment in a completely randomized design with two genotypes (varieties neda and fajr) in four salinity levels (zero, 40, 80 and 120 mm sodium chloride) and was performed in triplicate. results ...

   Phenolic extracts of canola (Brassica napuse L.) contains substances that inhibited the germination and seedling growth of soybean (Glycin max L.). These compounds also affect activity of some enzymes. Hear, we investigated the allelopathic effects of various canola plant parts on soybean germination, seedling growth, and biochemical aspects. Phenolic extract of canola shoot (including leaf,...

seeds of nine sugar beet lines: five drought tolerant, two susceptible, and two medium tolerant were washed, sterilised, dried, and sown in water agar medium for germination test. seedling growth characters such as cotyledon fresh weight (cfw), cotyledon dry weight (cdw), root fresh weight (rfw), root dry weight (rdw), and root length (rl) were determined after the end of 28 days period of expe...

in order to study the effect of compost and salinity stress on seedling growth and generative traits of wheat (sivand cultivar) a pot experiment was conducted based on complete randomized design arranged in factorial with six replications at the research greenhouse, faculty of agriculture, mashhad branch, islamic azad university, mashhad, iran, during in cropping season 2013-2014. factors were ...
