Switchgrass is a perennial C4 plant with great potential as a bioenergy source and, thus, a high demand for establishment from seed. This research investigated the effects of ultrasound treatment on germination and seedling growth in switchgrass. Using an orthogonal matrix design, conditions for the ultrasound pretreatment in switchgrass seed, including sonication time (factor A), sonication te...

in order to investigate the effect of pruning and potassium nutrition on pumpkin grain yield and quality, a factorial experiment based on complete block design with four replications was carried out in nooshar village of ardabil province, ardabil, iran, in 2007. experimental factors include potassium nutrition in three level (0, 75 and 150 kg/ha from potassium sulfate) and stem pruning (without...

Eleven salt tolerant bacteria isolated from different sources (soil, plants) and their transformed strains were used to study their influence on Triticum aestivum var. Inqlab-91 growth under salt (100 mM NaCl) stress. Salt stress caused reduction in germination (19.4%), seedling growth (46%) and fresh weight (39%) in non-inoculated plants. In general, both wild and transformed strains stimulate...

Mechanization and simplification are inevitable trends in agriculture production to decrease input demands and simultaneously improve resource use efficiency. Dry direct-seeded rice is a resource-saving cropping system and has been considered as a replacement for traditional transplanted rice. However, the poor establishment of dry direct-seeded early rice, primarily induced by chilling stress,...

In order to explore how plant autotoxicity changes with climate warming, the autotoxicity of P. schrenkiana needles' water extract, organic extract fractions, and key allelochemical DHAP was systemically investigated at the temperature rising 2 and 4°C based on the data-monitored soil temperature during the last decade in the stage of Schrenk spruce regeneration (seed germination and seedling g...

An experiment was conducted to study the effects of different soil media on seed germination and seedling growth of peach during 2001 and 2002 in Orakzai Agency. Different soil media alone and in combination used for seed germination of peach were Farm Yard Manure, Saw dust, Canal silt, FYM + Sawdust, FYM + Canal silt, Sawdust + Silt and FYM + Sawdust +Silt. Different media showed non significa...

A laboratory research carried out to evaluate the effect of drought stress on germination characteristics in two 'Indian' and 'Isfahanian' populations of Fenugreek. This experiment performed in a factorial experiment based on a completely randomized design with three replicates. Four levels of drought stress applied by using polyethylene glycol 6000. Percentage of germination, germination rate,...

Although the functional roles of zinc finger-containing glycine-rich RNA-binding proteins (RZs) have been characterized in several plant species, including Arabidopsis thaliana and rice (Oryza sativa), the physiological functions of RZs in wheat (Triticum aestivum) remain largely unknown. Here, the functional roles of the three wheat RZ family members, named TaRZ1, TaRZ2, and TaRZ3, were invest...

Indoleacetic acid and abscisic acid are present in cereal seeds. It is believed that they play roles in seed maturation and germination. Modification of environmental conditions can inhibit or modify germination and seedling elongation. Our aim is to analyse the role played by IAA and ABA during the anoxia seedlings growth in lack of oxygen comparing rice, Oryza sativa, the only crop plant able...
