Eggplant is an important vegetable crop in Kuwait. Eggplant is considered to have moderately sensitive salt-tolerance, though no quantitative information is available on its salt sensitivity. Selecting salt-tolerant genotypes in eggplant is an ongoing project at Kuwait Institute for Scientific Research. Towards the goal of selecting salt-tolerant genotypes in eggplant a completely randomized experiment using 10 cultivars, replicated 3 times were tested against 2 levels of high salinity stress (EC MS.cm-1 at 25°C, 15.0 and 18.0) along with the control (EC MS.cm-1 at 25°C, 3.0). The experiment was conducted on 15 days old seedlings inside a greenhouse. Data on shoot length and visual observations on leaf necrosis, leaf collapse and root color was also recorded. There was a clear degree of variability as well as significant differences in growth and final survival, between cultivars at 2 levels of salinity stress. Those genotypes that showed significant higher growth rates and survival without any signs on leaf necrosis and root collapse formed the basis salt-tolerant genotypes.

Agricultural development in Kuwait faces many problems and obstacles, such as limitation of water resources for irrigation, soils conditions, climatic extreme (particularly during the summer periods), and trained labor. With these extreme conditions for agricultural development in Kuwait, there is a strong demand from the public and the government for agricultural activities, particularly in urban landscape and greenery. World travel has enhanced the public's desire for the beautification of the urban areas and has emphasized the importance of the urban landscape. Planning urban landscape and greenery for Kuwait depends on various variables and efficient management of limited resources. Irrigation water is limited in Kuwait, and the quality of water is deteriorating from over-pumping of underground water and increased soil salinity by over irrigation and lack of drainage. Efficient irrigation-water management can be improved in Kuwait with enhanced irrigation research and implementation of the recommendations of this research. Research topics can also include water evaporation, which is high in Kuwait, and the introduction of mulching materials to improve water irrigation efficiency. Most of the soils in Kuwait are sandy with limited organic materials and plant nutrients. Research in soil fertility and plant uptake of nutrients is essential for any agricultural activities. Introducing ornamental plants tolerant to drought, salinity, and heat is a continuous research component of urban landscape and greenery in Kuwait. Training local staff in basic agricultural activities and research development should improve resource management and enhance the greenery of Kuwait.

Abstract

Lateral buds situated along the stem axis of a Cymbidium pseudobulb show a gradient in their degree of differentiation. It is shown that buds situated on the swollen upper part of the pseudobulb, normally inhibited in their growth and development by apical dominance, are capable of evolving either into floral shoots or into protocorms and vegetative shoots. A new method, both simple and rapid, of clonal multiplication of Cymbidium is described.
