This present communication deals with the anatomical identification of wood samples of an ancient archaeological monument in India, Sri Vishnu temple, Kadavallur in Thrissur (Kerala) and the consolidation of fissures and cracks formed due to seasoning over a period of time using neem gum and preservation using cashew nut shell liquid extract. Neem gum which has anti-bacterial qualities and CNSL organic extract which has anti-termite and anti-fungal preservative action are found suitable for conservation and preservation of these sculptures. The active ingredient in organic preservative, CNSL, was analysed using HPLC and compared using UV spectra. The peaks of monoene, diene and triene in anachardic acid are visible in the spectra. The preservative, CNSL, also enhanced the aesthetic appeal of the jack wood sculptures. CNSL-coated jack wood had lower moisture absorption as demonstrated by Karsten tube experiment. The results imply that the strength of the material formed out of neem gum and wood powder used for filling of cracks and fissures can be modified as per requirement using distilled water and that the application is reversible. This method of conservation was found suitable under warm and humid conditions to which these sculptures are subjected to.Keywords

A study on the physiology of ischolar_main parasitism in sandal (Santalum album L.) was conducted by comparing a six-year-old sandal grown alone and along with a host (Casuarina equisetifolia). Although maximum haustorial connections were observed when grown along with the host, sandal formed haustorial connections with plants including grass up to a distance of 3 m. Anatomical studies on haustoria indicated a vascular connectivity between the host and sandal. While the haustoria functioned as a physiological unit supporting nutritional requirements of sandal, direct lumen-lumen xylem connections between sandal and host were absent. Functional status of the haustorial connection was studied by radio-labelling the host (Casuarina) and nearby grass with phosphorus (32P). Presence of translocated 32P in sandal was noticed after six hours of labelling the host. 32P activity was noticed from eight days up to 16 days after which then it started decreasing. Study with multiple hosts revealed that the extent of translocation from hosts to sandal varied from 28.9% (coconut + Casuarina + rubber as host) to 78.5% (Casuarina + rubber as hosts). Reverse translocation of 32P from sandal to host was also observed. The study concludes that it is not necessary to plant the host along with the sandal as it is practiced presently.Keywords
