Mulberry grafting season is normally a one month period starting at the end of March. Such a short period creates a shortage of qualified grafters and inflates wages. Pine tree sawdust was tested as a medium in which to preserve graftages. Sawdust was moistened to two ratios of water to dry weight of sawdust (1.5 and 2.0). Scions were either grafted the same day they were colleted or first incubated for 10 days at 15°C. Grafting period could be extended to the middle of February under 1.5 times moisture content and fresh scions. Preservation of scions increased water content T-N. P2O5. CaO and inositol. whereas decreased total C, glucose and fructose. With no preservation total C decreased, inositol increased slightly early March followed sharp decrease, and sucrose increased with time.
