Northward expansion of Thalassia testudinum (turtle grass) in Laguna Madre is occurring faster than can be explained by rhizome growth. We hypothesized that seedling establishment can account for the measured rates of meadow expansion and that seedling carbohydrate reserves are utilized until the plant is photosynthetically self-sufficient. To address seedling establishment, we estimated seed o...

In the present study, 50 genotypes of tomatoes were tested in roll towel method using seven levels salt concentration from 0 to 120 mM NaCl with an interval 20 at laboratory conditions. Results showed that out genotypes, only 38 tomato germinated under a moderate salinity level 80mM NaCl. The highest seedling fresh and dry weights observed LE-14 (0.271 0.045, respectively) which on par LE-1, LE...

A pot culture experiment was conducted to study the effect of biomass power plant effluent on seed germination, seedling growth and chlorophyll content of green gram (variety LGG 460) have been estimated at different effluent concentrations and time intervals. The effluent is alkaline in nature (pH 8.5), odorless, and comprises of heavy metals such as Cr (0.071 mg l(-1)), Cu (0.014 mg l(-1)), M...

The demand for bigger, better, faster-growing seedlings has been ever-growing. As a result, forest seedling production is a continually evolving technology in reforestation. Evaluating seedling quality is crucial for understanding seedling development in the nursery, as well as subsequent field growth and survival. Stock quality, however, often is assessed inconsistently and on only a limited b...

today, the production of healthy and high quality seedlings is the main factors of success in growing vegetables such as tomato. hence, in order to investigate the effect of different levels of vermicompost and nitrogen on the growth parameters of tomato seedlings (lycopersicon esculentum mill. cv. rio grande), a factorial experiment was conducted in a randomized complete design with three repl...

 Background: As Moringa peregrina is a valuable medicinal plant in traditional medicine, it is necessary to determine responses of this plant to salinity.  Objective: To determine some biochemical and growth responses of Moringa peregrina to salinity at the seedling stage. Methods: This experiment was conducted in Institute of Medicinal Plants-ACECR, on base of factorial experiment as ...

SUMMER 2000 6 NYSTA Research Reports A study was conducted to evalu ate golf putting green establish ment procedures with four creeping bentgrass (Agrostis palustris Huds.) cultivars: Penncross, Penn A-4, L93, and SR1119. Five seed rates were used (0.5, 1.0, 2, and 4 lb.) with five seed treatments: metalaxyl (Apron), Pseudomonas aureofaciens, Azospirillum brasilience, Enterobacter cloacae, and ...

abstract recent interest in describing the spatial distribution patterns of weeds through using interpolation methods has increased to estimate weed seedling density from spatially refferenced data and evaluation of applicable to site-specific weed management. in this research, a multi layer perceptron neural network (mlpnn) model was developed to predict the spatial distribution of h. glaucum ...
