Early seedling vigor (ESV) is the essential trait for direct seeded rice to dominate and smother the weed growth. In this regard, 629 rice genotypes were studied for their morphological and physiological responses in the field under direct seeded aerobic situation on 14th, 28th and 56th days after sowing (DAS). It was determined that the early observations taken on 14th and 28th DAS were reliab...

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...

Most red lentil produced worldwide is consumed in dehulled form, and post-harvest milling and splitting qualities are major concerns in the secondary processing industry. Lentil producers in northern temperate regions usually apply pre-harvest desiccants as harvest aids to accelerate the lentil crop drying process and facilitate harvesting operations. This paper reports on field studies conduct...

this research evaluated the effects of gibberellin (ga3) and abscisic acid (aba) on emergence capability, rate of emergence, vigor index and some physiological characters of chickpea seedling (cicer arietinum l.) in a field experiment (as split) under dry and irrigated conditions. seeds were primed with 0, 50, 100 and 150 ppm of each phytohormones. examined chickpea cultivar was azad. the resul...

in order to study the effect of folic acid on seed reserves partitioning and early vigor of seedlings of kavir wheat cultivar, an experiment was conducted in a completely randomized design with 0, 12.5, 25, 50, 100 and 200 mm of folic acid. results of this study indicated that dry weight of seeds decreased in a same pattern in all treatments and about 6-8% of total seed was structural section. ...

We used 14C tracers to determine photosynthate distribution in cherrybark oak (Quercus pagoda Raf.) seedling sprouts following release from competing mid-story vegetation. Fall acquisition of labeled photosynthates by seedlings followed expected source-sink patterns, with root and basal stem tissues serving as the primary sinks. Four months after the seedlings had been labeled with 14C, they we...
