THE STUDYING OF THE EFFECTS OF SALINITY TENSION ON THE GROWTH PARTICULARS AND THE PROCEDURE OF CORN (ZEA MAYS)

Certainly, the salinity influences on about of 10 percent of cultivating lands of the agricultural plants of the world. All of the soils are content of salts of solution in water but, when the amount of these salts is prejudicial for budding of seeds, in this case, they influence on the growth and operation of plant. Corn have spared fastly and have formed the main food, because of its numerous particulars especially, compatibility power with various climate conditions. This research lasted for 5 months and for morphological and physiological particulars and the relation of their particulars with bearing of salinity in the farm of agricultural college of shahid Bahounar university of Kerman. In this stage, two variety of maize of single cross (504) and three v cross (647) which were influenced four levels of salinity attendances of 2, 4, 6, 8 ds/m that resulting in compounding of two salt of sodium chloride and calcium chloride in the proportion of 1:5 were studied in yet factor in the farm of project of completely accidental with 3 repetitions. In growth stage, salinity decreased the characteristics of tem such as dry weight of stem, stem diameter and stem length. Although, sensitiveness of these characteristic to salt density was not similar, and stem length and stem diameter attributes to salinity were most resistant and dry weight was most sensitive of attribute to salinity. In addition to the negative effects of salinity tension on characteristics of stem, the characteristics of leaf ware influenced by salinity. In addition to, the decreasing of the numbers of leaves, the leaf surface decreased, with increasing of salinity. Salinity had negative effects on operation and the elements of procedure of maize. The seed procedure, the weight of 100 seeds, the numbers of row in maize and the number of seeds in raw decreased.
