Abstract:
Zizyphus nummularia tree is one of the tropical fruits, which its appearance is in the south of central Asia. This paper is done for surveying the effective methods in germinations and improvements of germinated seed characteristic. For this purpose, a test is done as a random scheme on seed germination of this tree with five cares in four iteration. Cares are consist of distilled water, mechanical Scarification with rasper for ۱۵ minutes and the care's combinatory effects was with Gibberelic acid (۱۰۰, ۵۰۰ and ۱۰۰۰ppm) and Potasium nitrate. results obtained from number of germinated seeds, germination percent, speed of leg growth, speed of stem growth has shown that combinatory cares are more effective that mechanical Scarification care cause ۲۴ % germination and mechanical and Gibberelic acid combinatory scratch care۵ caused ۵۰۰ ppm and Potassium nitrate caused ۰.۲% ۴۴% germination and improvement in leg and stem growth. Increasing in Gibberelic acid caused in intense decrease in germination. However, without any outstanding effect in leg and stem growth. Therefore, we can mention that in lotus seed besides Scarification and lowering the crust thickness, using the hormones is effective in increasing of germination power.
