A set of laboratory tests was conducted in 2015, at the Central Seed Administration, Ministry Agriculture andForestry, Khartoum, Sudan, with objective to investigate effect late sowing and hydro priming times on some seed vigour attributes five chickpea lines ( DR1-27-5; DR1-44; DR1-109; DR1-114 DR1- 115). Seeds were provided by Hudeiba Research Station, from planting optimum date (November); (...

Quantitative trait loci (QTLs) for shoot biomass were identified in wheat grown on a soil high in total phosphorus (P) but low in plant-available P. The two populations screened included recombinant inbred lines (RILs) from Chuan-Mai 18/Vigour 18 and doubled-haploid lines from Kukri/Janz. Glasshouse-grown plants were harvested at the five-leaf stage. Seven QTLs for shoot biomass were identified...

Two field experiments in 1993 and 1994 as well as a laboratory germination experiment were conducted on the Egyptian cotton cultivar Giza 75 (Gossypium barbadense) to determine the effect of six concentrations of kinetin (6-furfurylaminopurine) ranging from 0 to 10.0 mg l(-1) and three different methods of application: (A) seeds were soaked for 24 h before germination (laboratory experiment) or...

This study develops a cartographic index of forest stands vigour from Ikonos imagery data. The study area located at GOUNAMITZ (New-Brunswick, Canada) consists mainly of fir, tolerant and intolerant hardwoods at mature and overmature stages. Forest inventory plots were set up in the stands; dendrometric measures (height, DBH, annual increment, etc.) were collected and used to estimate reference...

Vitis vinifera scions are commonly grafted onto rootstocks of other grape species to influence scion vigour and provide resistance to soil-borne pests and abiotic stress; however, the mechanisms by which rootstocks affect scion physiology remain unknown. This study characterized the hydraulic physiology of Vitis rootstocks that vary in vigour classification by investigating aquaporin (VvPIP) ge...

A factorial experiment with two factors was carried out at the Seed Technology Lab., College of Agriculture, University Baghdad in 2018 order to study effect seed priming gibberellic acid (GA3) (0, 100, 300 and 500 mgL-1) on germination seedling growth deteriorated oat cultivars (Shifaa, Shofan11). The complete randomized design used four replications. results showed that cultivars, soaking dif...

Poor seed germination is a major issue in teak (Tectona grandis) propagation. Teak dormancy thought to be the reason for delayed germination. So far, specific mechanisms have not yet been identified. In order study influence of presowing treatments on germination, seedling vigour, and biochemical attributes fresh drupes collected from production area Top Slip Tamil Nadu. The were subjected diff...

Seed germination is considered a critical phase in plant development and relatively sensitive to heavy metals. White poplar (Populus alba) trees tend to accumulate Cd and Zn in their tissues. We tested if soil contamination can affect P. alba progeny, reduced seed germination and explored the distribution of mineral elements in the seed. For this purpose, fruits and seeds from female P. alba tr...

Magnetic seed treatment is one of the physical pre-sowing seed treatments to enhance the performance of crop plants. In our earlier experiment, we found significant increase in germination and vigour characteristics of maize (Zea mays L.) seeds subjected to magnetic fields. Among various combinations of magnetic field (MF) strength and duration, best results were obtained with MF of 100 mT for ...
