A study on influence of seed orientation on seed germination of three species of rattans namely, Calamus prasinus, C. stoloniferus and C. thwaitesii made by sowing the seeds at 2 cm depth in vertical (micropyle end upward), horizontal (micropylar end sideward) and in vertical(micropylar end downward) orientations. Maximum germination of 80% in seeds of C. prasinus recorded in inverted position ...

Seeds of lettuce (Lactuca sativa L. cv. Grand Rapids) were imbibed and given either short irradiation with red or far red light prior to drying or dried under continuous red or far red light. Seeds treated with either short or continuous red germinate in darkness, whereas seeds treated with either short or continuous far red require a short exposure to red light, after a period of imbibition, t...

Peanut or groundnut (Arachis hypogaea L.) sown in early spring often has poor seed germination and seedling development. The influence of soil temperature on seedling emergence and early growth of six peanut cultivars (Florida MDR98, Southern Runner, Georgia Green, SunOleic 97R, Florunner and C-99R) was studied in natural field soil profiles in temperature-gradient greenhouses. We evaluated the...

Canna indicaL.roots are used for medicinal purpose. A decoction of the root with fermented rice is used in the treatment of gonorrhea and amenorrhea. The seed of canna is extremely hard, and needs to be "scarified" before sowing. The aim of the present investigation is to determine the hardiness problem of the seed. The seed sample was collected from the IARI, New Delhi in 2008. The wo...

root and crown rot of sugar beet caused by rhizoctonia solani ag2-2 is a destructive disease in the main sugar beet growing areas. use of resistant cultivars is the most effective and environmentally safe way to control the disease. in order to find resistant genotypes, 70 sugar beet lines together with resistant and susceptible checks were evaluated against a highly virulent isolate of r.solan...

Although a cover of grasses and legumes may be established on exposed mountain subsoils through seeding and the use of a complete fertiliser, this cover is not likely to last for more than a few years without the application of more fertiliser. Native tussock species once established in the protection of other low-growing species might persist and provide stability over a longer period. This pa...

Rice in the U.S. is frequently seeded at low rates and treated before sowing with neonicotinoid or anthranilic diamide insecticides to target the rice water weevil. A previous study of the influence of seeding rate on rice water weevil densities showed an inverse relationship between seeding rates and immature weevil densities. This study investigated interactive effects of seeding rate and see...

to evaluate the effects of seed priming with salicylic acid on quality and baking traits of wheat flour, cv. alvand, under different sowing dates, a factorial experiment was conducted on the basis of complete randomized block design. the factors were seed priming with salicylic acid (including untreated seeds or control treatment, 400, 800, 1200, 1600, 2000 and 2400 µm concentrations of salicyl...

                In order to determine the best developmental stage of three common bean cultivars (Talash, COS16 and Khomain) at which maximum seed quality is attained under different irrigation regimes (I1-irrigation after 60 mm, I2-irrigation after 80 mm and I3-irrigation after 100 mm evaporation from class A pan), a split plot experiment (using R.C.B. design) with 3 replications was conducte...
