Seed Technology Information

Propagation material:  The seeds retain their viability for about one year under normal storage conditions and are the best propagation material. Fruits are collected in March for the extraction of seeds. Seedlings or stumps prepared from two-year-old nursery seedlings are used for planting in the field^[2].

Seed Propagation :

Red Sanders Seed

Seed Collection : Dry pods are collected from trees in February-June, then dried in the sun for 3 days and stored in bamboo baskets or gunny bags till required. There is no loss of viability for at least 8 months. It looses its viability definitely if kept for more than one year^[1].

Pretreatment : Soaking of pods in cold water for 3 days increases the germinative capacity very much, also if the pods are immersed in cowdung slurry for 48 hrs before sowing^[1].

Sowing Method : Raised or flat nursery beds with well- drained soil is prepared. The soil should be dry to 30 cms deep and clods broken to powder. Farm yard manure is mixed with soil.  Standard size beds of 12x1.2 m, raised above the ground are prepared. The entire pod with wing as collected are sown. Pretreated pods is sown per bed and is covered by a thin layer of soil or hay and profusely watered^[1].

Sowing Season : During July-September^[1]

Germination Duration : Germination takes 15 to 20 days^[1].

Germination Percent : Germination percent varies from 10 to 80 percent^[1].
