Balanites aegyptiaca trees have multiple benefits to people in the arid/semi arid regions of Nigeria. Despite importance this species, it is still found wild. In order encourage domestication tree study was conducted determine optimum light requirement and best sowing position B. seeds that would enhance germination. The experiment laid out a 4×3 factorial completely randomized design (CRD) rep...

Seeds of pearl millet (Pennisetum glaucum (L) R. Br.) from six provenances of Tunisia were subjected to germination and shoot and root length tests on filter paper treated with polyethylene glycol 6000 (PEG 6000) solutions made up to provide osmotic potentials of 0, -1 and -2 MPa. Mean germination percent for all provenances decreased about 73% in -2 MPa compared to control (0 MPa) treatment. O...

in order to investigate the germination characteristics and cardinal temperatures of biotype alhaji pseudalhagi, a laboratory experiment was conducted randomized completely design with four replications of 25 seeds. various constant temperatures 5, 8, 10, 15, 20, 25, 30, 35, 40, 45 and 50ºc were considered. the characteristics such as percentage of seed germination, rate of seed germination, th...

We attempted to create a new germplasm of cucumber cultivar Chinese long (9930) using different doses of ethyl methyl sulfonate (EMS) to induce variability. We tested EMS concentration (0, 0.5, 1.0, 1.5, 2, 3% v/v) with post-treatment (0.1 M Na2S2O3 and water), EMS concentration (0, 0.5, 1.0, 1.5% v/v) over different treatment times (8, 16, 24 h), and EMS concentration (0, 0.5, 1.0, 1.5% v/v) w...

Five cycles of germination NaC1 tolerant alfalfa and the source population, 'Mesa Sirsa', were germinated in four salt solutions (NaC1, NaNO3, KC1, and KNO3) and Mannitol to try to determine the general mechanism involved in seed germination salt tolerance. Average germination over all germplasm sources in NaC1, NaNO3, KC1, KNO3, and Mannitol were 44.80, 38.88, 36.24, 29.07, and 60.93 percent, ...

The physical mechanism of seed germination and its inhibition by abscisic acid (ABA) in Brassica napus L. was investigated, using volumetric growth (= water uptake) rate (dV/dt), water conductance (L), cell wall extensibility coefficient (m), osmotic pressure ( product operator(i)), water potential (Psi(i)), turgor pressure (P), and minimum turgor for cell expansion (Y) of the intact embryo as ...

Arsenic (As) contamination is an important environmental consequence in some parts of salinity-affected South (S) and South-East (SE) Asia. In this study, we investigated the individual and combined phytotoxicity of arsenic (As) [arsenate; As(V)] and salinity (NaCl) on early seedling growth (ESG) of saline-tolerant and non-tolerant rice varieties. Germination percentage (GP), germination speed ...

Chicory (Cichorium intybus L.) seed production includes sorting to remove foreign materials and non-viable seeds. A machine vision system was developed to monitor the fluorescence in order to detect the immature chicory seeds. It comprised a monochromatic light source, a highpass filter and a monochromatic CCD camera sensitive to red and infrared. With this device, blue light reflected by the s...
