The study was conducted to investigate the effects of ethylenediaminetetraacetic acid (EDTA) on seedling emergence, morphological characteristics, and photosynthetic pigments of Chenopodium album (L.) in lead (Pb) contaminated soil. The Pb contaminated soils were taken from Hirmand River. The soil samples mixed with 0.71 g Li-1 Pb (PbNO3)2 to increase the Pb concentration. EDTA was added to the...

today, the production of healthy and high quality seedlings is the main factors of success in growing vegetables such as tomato. hence, in order to investigate the effect of different levels of vermicompost and nitrogen on the growth parameters of tomato seedlings (lycopersicon esculentum mill. cv. rio grande), a factorial experiment was conducted in a randomized complete design with three repl...

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...

the effect of electromagnetic field was examined on zinnia (zinnia elegans) seeds to enhance seed germination and early growth. the seeds were exposed to four magnetic strengths of 15, 100, 400 and 800 mt in four durations of 30, 60, 120 and 240 min. the experiments were carried out in two forms of laboratory germination and soil emergence. results showed that magnetic field application enhance...

study of magnetic field and seed hydropriming effects on tomato seed germination was done in laboratory of ferdowsi university of mashhad, iran. the experiment was as factorial experiment based on randomized completely design, which was including two level of hydropriming (use of dry seed and soaked seed in distilled water for five hours) and eight level of magnetic field (pretreatment of seeds...

background and objectives: seed vigour is the resultant of a broad range of physiological processes which have genetic background. the study of genetic variation, play an important role in enhancing the ability of breeders in selection and breeding operation. this study aimed to evaluate rice genotypes with the physiological and morphological characteristics related to seed vigour and grouping ...
