Determination of the Effects of Different Salt Concentrations on Germination in Bean (Phaseolus vulgaris L.) and Cowpea (Vigna unguiculata L.)
Öz
Today, the importance of legumes is even more important as the weather's ability to bind free
nitrogen to the soil, environmentalism and the importance of sustainable agriculture. The amount
of nitrogen the edible legumes attach to the soil varies depending on the variety and environmental
conditions, generally around 5-20 kg / ha per year. Beans are in the first place among edible grain
legumes in terms of planting area and production in the world. Cowpea is a leguminous plant with
a consumption shape like bean, and it is a plant that will not live in harmony with the consumer's
consumption in the regions where beans are grown. Cowpea is a plant that is regarded as animal
feed besides human nutrition. Salt stress limits product yield by affecting plant growth, especially
in arid and semi-arid regions The amount of excess fertilizer which is used in the construction of
agriculture can not be taken by plants and causes to be salted. In Turkey, there are about 1.5
million hectares of salinity and alkalinity problems. This is equivalent to about 32.5% of the land
suitable for irrigation. This study was undertaken to determine the physiological responses of the
bean and cowpea, to show that the salt stress faced in increasingly salty soils has been shown
during the germination phase. In this study, the effects of 5 different salt doses (0-50-100-150-200
mM) on germination were tried to be determined in cowpea and bean. The germination rate, plumu la fresh and dry weight, radicula fresh and dry weight, plumula length and radicle length
characteristics were investigated. As a result of the study, a decrease in germination rate was
observed in increasing salt concentrations.
