Collection and evaluation of Kenyan tomato landraces with special reference to salt and drought tolerance
(AGRIS, 1995)The tomato is a major vegetable species in Kenya. By providing salt and drought tolerant varieties, their productivity in the marginal areas of Kenya could be significantly improved. The aim of this work was to collect ... -
Effects of Acid Scarification, Priming with PEG, NaCI or Sea Water as Osmoticum and Dehydration on Spinach Seed Germination at 30°C
(Japanese Society for Horticultural Science, 2005)Spinach (Spinacia oleracea L.) seeds were scarified with an 18 N H2S04 solution, then primed for one week at 10De in PEG- 6000, NaCl or natural sea water. Germination tests were carried out at 30De, which is normally ... -
Assessment of tolerance to salt stress in Kenyan tomato germplasm
(International Journal of Plant Breeding, 1997)Tomato is an important vegetable crop in Kenya and the development of salt tolerant cultivars would enhance its productivity in the vast marginal areas of the country. This study was aimed at determining the magnitude of ... -
