Abrus precatorius ia a perennial plant. It has natural regeneration of this plant species is  very low regeneration;  moreover this plant very difficult to regenerate from seed materials,  because the seed coats are very hard; this coat stop the penetration of water & gases. If you require mass propagation of this plant, go for rooting of stem cuttings otherwise plant tissue culture techniques. 

Dear Kalidass, I'm grateful for your kind response!

What if I scarify this seeds? (I mean scarification) Could it help for germination?

I bought its seeds through e-bay, they were sent from India, as I can judge on the postal stamp.

Can you tell me what kind of soil is preferable for Abrus? Does it prefer copious irrigation or middle?

It's interesting to note, firstly I tried to sprout its seeds on a layer of wet paper in a Petri cup. As I mentioned above, only few seeds swelled, but they were attacked by a mould, in contrast of them the swelling-proof seeds did not attract the pathogenic fungi. But, it may be interest to note, that the fungi completely destroyed the testa at a few days but did not affect the cotyledons. I find myself thinking that scarification by fungi could be a good method.

Garden soil is preferable but seed materials have to treat with bavistion or any fungicides it shouldn't affect fungi. Scarification method is more suitable but carefully handle because sometimes embryo may be damage. Thanks for charing of valuable information.

This is my abrus on the second week after germination :)

Your abrus plant is very good conditions for two weeks.  If you need fastest then add few amount of nutrient solutions and also maintain humidity and temperature.  After 8 weeks do gardening steps like high humidity and low temperature ; medium humidity & temperature;  finally low humidity and high temperature until some interval spray fungicides .

Thank you very much! :)

I would like to share the results of my another attempting to germinate seeds of Abrus, it was much more successful :)

At first, I put ca. 40 seeds into 50 ml vial and added a solution of 3% aqueous hydrogen peroxide just to cover the seeds, and kept them for 6 hours at +32 С degree. On the end of sixth hour, I dried the seeds on the layer of filter paper. Only 24 seeds have swelled and their testa faded and dehisced, but I turned attention on another layer of the testa. It was colorless, transparent and elastic. I decided to pierce it with a needle and put the seeds into the humid soil. During my experiment average temperature was 28C at the daytime, and 16-18C at nights. Only 2 days has left, I got two germinate seeds and another two during next four days. So the germinative value is about 16%, I tend to think it is a very good results :)

Hope, this information will useful.

You have done very good achievements for this species.  But 16% is a average vital index, if you have more than 50% , it is very much useful for mass propagation / multiplication.  Otherwise the same chemical treat with various concentration at time interval may be you chance to get better results.
