Quality Evalaution of Toona ciliata M. Roem Seeds

The present study was conducted at Forest Tree Seed Laboratory, Silviculture Division, Forest Research Institute, Dehradun (Uttarakhand) during 2013 on the seeds of Toona ciliata (Cedrela toona) known as Toon, Red Cedar, Moulmein Cedar. The data were recorded for purity (%), seed weight (g), moisture content of the seed (%), seed viability, seed vigour, germination (%), ischolar_main- shoot lengths (cm) for quality evaluation of the seeds of Toona ciliata . The seeds of Toona ciliata was found to have a very high physical purity percentage i.e. 93.28 %. The average moisture content of the seeds was found to be 18.65% and weight of 1000 seeds was found to be 2.1 g. Due to low viability period, it is recommended to sow the seeds soon after collection.The seeds germinated was maximum in ambient temperature (55 %) followed by 25°C and 30°C. The mean ischolar_main length of the seedlings was approximately same in room temperature condition and 25°C temperature condition (0.6cm) followed by 30°C temperature (0.4 cm) but the mean shoot length of the seedlings was maximum at 25°C followed by 30°C and ambient temperature.
