Germination response of endangered medicinal plant, Levisticum officinale, to stratification and some plant growth regulators
Levisticum officinale is an important and endangered wild medicinal plant belongs to Apiaceae family. Pre experiment showed that seeds of this plant have some degree of dormancy and it‘s germination is very low. Therefore, a factorial experiment laid out in completely randomized design with 3 replications to evaluate the effect of different plant growth regulators […]
Germination of the tomato (Lycopersicon esculentum Mill.) in response to salt stress combined with hormones
Salt stress is a major environmental constraint most limiting plant productivity. Seeking salt-tolerant crops requires an examination of the behavior of the plant development including seed germination stage. The effects of NaCl stress (100 mM) combined or not with different solutions of phytohormones ABA (0.005 mM), GA3 (0.005 mM) and SA (0.5 mM) on germination […]
The survey of the effect of the acceleration aging and cold pretreatment on germination and other factors of the plantlet growth in two varieties of canola
One of the most important problems with oily plants like canola is their storage. Because if the storage of the seeds is not suitable the seeds will oxidize as they are oily and they lose their germination ability much faster than the seeds of the other plants. Therefore to assess the effect of cold and […]
Investigating the effect of drought stress induced by mannitol on germination and morphological properties of wheat inbred lines
To investigate the response of inbred lines of M82 and Babax wheat series to drought stress, which induced by mannitol, on growth stage of plant, a factorial experiment with a completely randomized design with 2 replicates in normal and drought stress condition on 169 in board lines, was performed. Ln this research the mannitol with […]
Germination percentage and growing behavior of Salix tetrasperma (Willow) as affected by size of branch cutting and low polythene tunnel
Propagation through branch cuttings is one of the best methods to produced tree nursery the yield of the tree produced from a cutting can be higher then a tree produced from seedlings, the conditions provided to them are important factor for getting good results. The aim of this study was to find the best size […]
Effect of bulb size on quality seed production of onion in Bangladesh
A study was conducted in the experimental farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur, which is situated at 24.040 N latitude and 90.40 E longitudes with an elevation of 8.4 meter from the sea level and in the 28th Agro ecological Zone (AEZ) during the year 2011 to 2012. The purpose of […]
Impact of climate on seed morphology and plant growth of Caesalpinia bonduc L. in West Africa
Caesalpinia bonduc L. is an important medicinal plant threatened by overexploitation. In the present study, the impact of climate on seed morphology, germination capacity, seedling and plant growth of C. bonduc were evaluated. A total of 2000 seeds were collected in Sudanian and Guinean climate zones of Africa and their length, width, thickness, weight and […]
Performance of some soybean Glycine max (L.) Merrill. cultivars under salinity stress to germination characters
In order to examine the effect of osmotic stress on six soybean cultivars i.e. Giza 21, Giza 22, Giza 35, Giza 82, Giza 83 and Giza 111 at germination stage to salinity stress i.e. 0, 3, 6, 9, 12 and 15 dSm-1 NaCl and to confirm seedling germination to examine a range of genetic variability […]
The effects of priming by folic acid and hydrogen peroxide on morpho-physiological traits in cannabis seeds (Cannabis sativa L.)
Effect of various folic acid and hydrogen peroxide concentration on some traits of cannabis performed based on randomized complete blocks design in research green house of Islamic Azad University of Mahabad, Iran. Experiments treatments were levels of folic acid (0,5,10,15,20,25,27Mm), hydrogen peroxide (0,7.5,15,22.5,30,37.5,40 Mm) and control (non-primed) which replicated 4 in 24 and 6 h […]
Effects of physical treatments on germination and stand establishment of sunflower (Helianthus annuus L. var. Hyson) under laboratory condition
Seed priming has been reported to enhance growth of plants. To evaluate the effect of some physical seed priming materials (ultrasonic, gamma, beta and laser irradiation, magnetic field and hydro-priming) on seed germination and growth of sunflower a laboratory experiment was conducted at Islamic Azad University of Tabriz branch, using completely randomized design, with three […]
