Within-species variations in drying and preservative intake properties: a case of two progenies of plantation grown Melia Dubia CAV

Abstract

Two progenies of 7 years old plantation grown Melia dubia Cav. were taken for carrying out studies on variability in drying and preservative intake properties. Terazava1 method of testing drying properties was used to give scores to various drying defects occurred in two progenies. The preservative intake properties like retention, penetration, treatability etc were determined using standard methods. Results indicate that the drying properties varied from progeny to progeny. Occurrence of the defects like surface checks were found to vary progeny to progeny, whereas, defects like surface deformation and honey combing didn’t vary. Variation in preservative properties like retention and treatability was found to vary. The study indicates that M. dubia species may possess considerable intra-species variation in drying and preservative intake properties in the plantations of seed origin.
