Effect of aqueous extracts of eucalyptus (Eucalyptus camaldulensis L.) on germination and seedling growth of wheat (Triticum aestivum L.).
Allelo-chemicals produced from leaves, roots, bark, fruits and seeds of many plants influence the growth and germination of another adjacent plant. A lab experiment was conducted to study the allelopathic effect of aqueous extracts of Eucalyptus leaves (Eucalyptus camaldulensis L.) on germination percentage and seedlings of three varieties of wheat. Experiment was laid out in […]
In vitro germination and seedling development of tunisian caper (Capparis spinosa L.)
Capparis spinosa L. (Capparaceae) is a perennial tropical and subtropical shrub plant known worldwide. Despite the increasing demand and economic importance of capers, little information is available regarding the propagation of this shrub. In fact, it is usually propagated by seed, but its percentage of germination is very low. In this report, in vitro seed […]
Germination sensitivity of Candlenut (Aleurites moluccana Willd) on burning, sowing depth, and positions of seeds in the field
The objective of the research was to assess the germination sensitivity of candlenut on burning, sowing depth, and seed positions in the field. The method used was a factorial in a randomized complete block design. With the least significant difference level of 5%, the results showed that germination rates were significantly sensitive on the interaction […]
Germination characters as affected by seed priming of some sunflower cultivars under salinity stress
To study the effect of seed priming in 1% NaCl or 0.3% KNO3 of some sunflower cultivars i.e. Sakha 53, Giza 102, Line S 102 and Line S 1 on critical stage of germination under salinity concentrations i.e. 0, 5, 10, 15, 20, 25, 30, 35 dSm-1 NaCl. Germination characters i.e. final germination percentage, germination […]
Germination characters as affected by seed priming of some safflower cultivars under salinity stress
To investigate the effect of seed priming treatments i.e. NaCl or KNo3 and non-primed seed of some safflower cultivars i.e. Giza 1, Line 168, and Line1697 on critical stage of germination under salinity concentrations of. 0, 3, 6, 9, 12, 15 and 18 dSm-1 NaCl. Laboratory experiment was conducted at Giza Central Seed Testing Laboratory […]
The Mediterranean Seawater: The impact on the germination and the seedlings emergence in three Acacia species
This study was conducted in order to compare the levels of tolerance to salinity in three Acacia species (Acacia dealbata Link., Acacia ehrenbergiana Hayne and Acacia tortilis (Forssk.) Hayne var. raddiana) during germination. We were able to determine the optimum conditions for germination to assess suitability for germination of these species under different concentrations of […]
Position dependent effect of oil palm (Elaeis guineensis Jacq.) seeds on germination aptitude
Oil palm seed germination is erratic, fluctuating between varieties and within seeds of the same fresh fruit bunch (FFB). The cause of the low rate of germination and within-FFB germination variation is not quite clear. This study was carried out to verify if seed position on the spikelet influences germination capacity (GP) in theoil palm. […]
Incidence of seedborne mycoflora and their effects on germination of maize seeds
A laboratory experiment was conducted with maize seed samples collected from four maize growing districts viz. Bogra, Gaibandha, Rangpur and Mymensingh of Bangladesh following blotter method. Nine species of fungi namely Aspergillus flavus, A. niger, Alternaria alternata, Bipolaris maydis, Curvularia lunata, Fusarium oxysporum, F. moniliforme, Penicillium oxalicum and Rhizopus stolonifer were identified. Among the species, […]
Effect of magnetically induced structural changes in water and cotton seed on germination behavior
Planting quality seed is a guarantee for optimum plant population and high yield. Cotton crop being grown and processed in hot environments is facing germination problems and climate change will aggravate it day by day. Magnetic treatment of water and seed is a safer option to enhance the seed germination. Water and seed stimulation magnetic […]
Evaluation of seed size and NaCl stress on germination and early seedling growth of sunflower (Helianthus annuus L.)
Sunflower is well adapted plant to tolerate moderately saline soil conditions. In order to investigate this circumstance, an experiment was conducted as a factorial with three factors arranged in completely randomized design with 4 replications and 50 seeds per replicate. Three cultivars (Azrgol, Eurofler and Record) made first factor, the second was made of seed […]
