Applies to the evaluation of cotyledons and primary leaves. Does not apply to the top bud or the evaluation of the surrounding tissue of the top bud. When the top bud or the top of the bud tissue necrosis, decay, regardless of cotyledons and primary leaves The situation is not normal seedlings. 3.5 Normal seedlings normalseedlings In good soil and suitable moisture, temperature and light conditions, with continued growth and development to become the potential of normal plant seedlings.
