Plant Reproduction, Instantiate problem

Hi everyone ! I am learning Unity and Javascript since 3 days now and I need your help for something.

I decided to practice all of what I learned by making a "plant" in unity, that would grow, change model, reproduce and die. For the growing, changing model and dying part everything works find, but I can't seem to make it reproduce.

When I instantiate a new plant from the original one, that new plant is as old as the original one. Any way I can solve this ?

var Vie : float = 60;

var Adult : float =40;

var Dead : float =20;

var Reproduction : boolean = true;

var Plant : GameObject;

function Update () {

Vie -= Time.deltaTime;

if(Vie<=0){ Destroy(gameObject);

}else if(Vie<=Adult){

var Fstep : MeshRenderer = gameObject.Find("PlantYoung").GetComponent(MeshRenderer); Fstep.enabled = false;

var Sstep : MeshRenderer = gameObject.Find("PlantAdult").GetComponent(MeshRenderer); Sstep.enabled = true;

}

if((Vie<=Adult) && (Reproduction)){ var position = Vector3(Random.Range(-10,10), 0, Random.Range (-10, 10)); Instantiate (Plant, position, Quaternion.identity); Reproduction = false;

}

if(Vie<=Dead){ Sstep.enabled = false;

var Tstep : MeshRenderer = gameObject.Find("PlantDead").GetComponent(MeshRenderer); Tstep.enabled = true;

}

}
