Pak. J. Bot.‚ 37(1): 131-139‚ 2005. SALINITY EFFECTS ON SEEDLING GROWTH AND YIELD COMPONENTS OF DIFFERENT INBRED RICE LINES AISHA SHEREEN‚ S. MUMTAZ‚ S. RAZA‚ M.A. KHAN AND S. SOLANGI Nuclear Institute of Agriculture‚ Tandojam‚ Pakistan. Abstract Water culture studies of short (seedling stage) and long term (maturity) stage were conducted to evaluate the effect of different levels of salinity (0‚ 50‚ 75 mM NaCl) on the growth‚ yield and yield components of different inbred rice lines.

Solder (/ˈsoʊldə/‚[1] /ˈsɒldə/[1] or in USA /ˈsɒdər/[2]) is a fusible metal alloy used to join together metal workpieces and having a melting point below that of the workpiece(s). Soft solder is typically thought of when solder or soldering is mentioned‚ with a typical melting range of 90 to 450 °C (190 to 840 °F).[3] It is commonly used in electronics‚ plumbing‚ and assembly of sheet metal parts. Manual soldering uses a soldering iron or soldering gun.Alloys that melt between 180 and 190 °C (360

“Is enough been done to counteract the effects of salinity in the Chowilla Region?” INTRODUCTION Chowilla Region is located in the river lands‚ 50km from Renmark‚ South Australia‚ commonly used for recreational use (SA.gov.au‚ 2012). Chowilla is a peaceful place‚ used to get away from the hectic pace of current life. The region is considered a Game Reserve and monitored by the Berri National Park headquarters. It also has the largest remaining native Riverine forest in South Australia‚ described

SALINITY Problems arise in the world due to salinity‚ as when the salt gets on to the top of the soil.....it causes disaster to the plants and trees. Salt comes in many forms in the natural environment—calcium‚ magnesium‚ carbonate‚ sodium chloride‚ bicarbonate‚ and sulphate. Many landscapes are naturally saline‚ but secondary salinity isn’t so natural‚ occurring when salts from deep within the earth are dissolved and deposited into soil and water as a result of

Abstract: : The purpose of studying the biological organisms in the Mpenjati estuary-beach system is to distinguish between organisms and estimate diversity within the estuary found at different locations along the estuary-beach profile in accordance with factors affecting the daily routines of these marine life and other aspects in which these organisms concur with. The organisms found in these waters play an important role in the ecosystems they function in therefore it is imperative to seek a

Converting Saltwater into Electricity I. Introduction The world we live in is abundant with food‚ life and resources‚ but we continue to use up non-renewable resources in massive amounts. As a result‚ the many nations and countries of the world will have to deal with water‚ food‚ and energy shortages‚ as an effect of overpopulation. This Project presents a new‚ derived energy source. It will also discuss the methods and ways we can utilize this environmentally-friendly resource to produce an efficient

irrigated-land salinity have become problematic for the Australian environment‚ despite the fact much of our natural landscape is naturally saline. The response of plants to salinity has been explained as a two-phase growth response. The first phase of growth reduction is characterised by osmotic stress due to salts in the outside solution‚ while the second phase develops after salt build-up in transpiring leaves and shows clear genotypic variation (Fortmeier and Schubert‚ 1995). Salinity impairs plant

SALINITY AND DEEP OCEAN CURRENTS OVERVIEW Ocean currents arise in many different ways. For example‚ wind pushes the water along the surface to form wind-driven currents. Deep ocean currents are caused by differences in water temperature and salinity. In this experiment‚ the students will hypothesize the cause of ocean currents and then develop a model to explain the role of salinity and density in deep ocean currents. CONCEPTS Salt water is more dense than fresh water‚ and is therefore

water‚ affects the germination of the seed? Purpose: To see if the salinity of the water affects the germination of the seed‚ before its put into the soil. Back Ground Information: Seed germination is the sprouting or growth of a seed into the start of a plant. When environmental factors such as moisture‚ temperature‚ oxygen‚ and sometimes light are appropriate‚ a viable seed will begin to germinate. Salinity (salt-affected) in plants can cause ionic stresses‚ especially since Na+ (sodium)
