improving germination of guava (psidium guajava) seeds by acid scarification
as seed germination of guava (psidium guajava) is poor and time-consuming, the effects of seed extraction technique and scarification methods on the seed germination and seedling growth of guava cv. allahabad safeda, were investigated. first experiment was conducted on extraction of guava seeds using sulfuric acid (h2so4) : seed ratios including: 1:5, 2:5 and 3:5) or manual extraction (control)...
متن کاملeffects of concentrated acid and hot water scarification treatments on germination parameters of tamarindus indica and acacia arabica
tamarinda (tamarindus indica) and indian gum arabica (acacia arabica) are two ornamental trees of beautiful shape, extensive shading, and tolerant to high temperatures, making them suitable alternatives for landscape design in warm- arid regions. tamarinda and indian gum arabica are commonly propagated by seed. however, seed physical dormancy causes delay in seed germination. this study was car...
متن کاملEffect of Water-Soaking and Air-Drying on Survival of Aphelenchoides besseyiinOryza sativa Seeds.
Several nematicides have been used to disinfest rice seeds contaminated with the white tip nematode, Aphelenchoides besseyi. We measured the efficacy of a standard disinfestation treatment that consists of soaking seeds in an aqueous emulsion of fenitrothion or fenthion and subsequently air-drying the seeds. We also measured the efficacy of the same treatments but without addition of nematicide...
متن کاملImpact of hot water soaking on antioxidant enzyme activities and some qualities of storage tomato fruits
Mature-green tomato fruits were soaked in hot water for 10 minutes at 35, 40, 45 or 50°C and then stored at 13°C for 20 days. Untreated fruits were soaking with tap water (22°C). The study showed that exposing fruit to hot water influenced peroxidase (POD) and catalase (CAT) activities. Activity of the two enzymes increased with the increasing of soaking temperature, except for the 50°C treatme...
متن کاملEffects of Various Treatments on Seed Germination and Growth of Carob (ceratonia Siliqua L.)
In this study, Ceratonia siliqua L. carob seeds harvested from both wild and cultivated genotypes in Turkey were subjected to mechanical scarification, soaking in hot water and dipping in sulfuric acid. All treatments hastened seed germination and seedling growth of carob compared to control. The germination percentage of control seeds were similar for both wild and cultivated genotypes (13%) a...
