    Default Scientists opinion on teak

    WHY CLONES ARE THE BEST IN TEAK?
    OPINIONS OF THE EMINENTS (DAY TO DAY MORE ARTICLES WILL BE ATTACHED);*
    1. BY Mr. R. S. NADGAUDA, Mr. S. V. KENDURKAR, and Mr. V. M. KULDKARNI *of NCL , PUNE *on TEAK TISSUE CULTURE FOR IMPROVED PRODUCTIVITY:
    Plant Tissue Culture occupies a central position in plant biotechnology, whether it is micro propagation of superior mother clones, conservation of germ plasm, genetic transformation or generation of novel plants through genetic engineering. It has long been realising that, tissue culture micro propagation of superior genotypes can result in capturing genetic gains, leading to increased productivity per unit area. Mass multiplication of the identified plus trees selected for higher growth, disease resistance and wood quality in vitro is known as micro propagation. This method is preferred over the conventional method of rooting; grafting and propagation through seeds as the plants produced are true to type, disease free and can be produced round the year. Here the method of choice is meristem culture.
    Tissue culture studies on teak with an aim to develop a micro propagation protocol for rapid multiplication of mature identified mother clones were undertaken way back in late seventies. Extensive studies were conducted on right from germination of seeds in vitro, protocol for seedling multiplication and most importantly culture of meristem from trees (80-100 yr. old) growing in Allapally forest, Maharashtra, India. The constraints of control of phenolics, contamination faced during the initiation and establishment of cultures were combated, shoot cultures were established, further multiplied and rooted in vitro to obtain complete plantlets which were successfully transplanted to soil (Guptha et. al., 1980) Tissue Culture raised plants were field planted at different places in Maharashtra and small scale field trials were conducted in collaboration with Maharashtra Forest Development Corporation, Maharashtra. The data received on the growth performance of these plants was inconsistent and could not be considered for the analysis of growth performance of tissue culture raised plants in the field. However during the same time a field trial in a randomized block design with seven replication was conducted at NCL, Pune to study the growth performance of tissue culture raised plantlets of seedlings and elite tree origin in comparison with seedlings raised from seeds. The significant increases in height and growth were reported in tissue culture raised plantlets of seedling and elite tree origin as compared to seedlings raised from seeds. The elite tree origin showed highest growth increment. Growth performance of these plants has been reported (Mascaranhas et.al., 1987, 1993).
    The performance of tissue culture raised plants of teak planted in 1994 at Madhya Pradesh has indicated an average increment of 17.85% for height over control within 6 years. In one of the trials planted using tissue culture raised plants in Chattisgarh, the height increment of tissue culture raised plants is 40.75% higher over control and girth increments 62.09% higher over control at the age of 3 years. The trial conducted at National Chemical Laboratory, Pune using tissue culture raised plants of clones has shown higher growth as against seed raised controls (although it is conducted in loamy soils).
    As an outcome of the extensive studies carried out at National Chemical Laboratory, Pune the achievements are very significant. The most striking observations in the field are that tissue culture raised plants showed more than 90% survival, very high uniformity and accelerated growth, resulting into reduction in rotation time. The results of specific gravity analysis are encouraging suggesting that the technology has definite advantages and if exploited commercially, can lead to significant gains.
    CONCLUSION OF SEVEN HILLS INVITRO LABS PVT. LTD., TIRUPATI:
    We are saying that, not only the opinions of the above eminents, but also many surveys are proving that, selected clones are the best for raising TEAK plantations to obtain maximum yield with maximum reduction of rotation period. By adopting tissue culture technology, We the SEVEN HILLS INVITRO LABS PVT.LTD., TIRUPATI, are producing Andhra Pradesh Forest Department identified TEAK CLONES, what are suitable for planting in all most all the areas in 130 countries in the world, having rainfall in between 400mm to 2000mm above. We are proudly reiterating that, we the SEVEN HILLS INVITRO LABS PVT.LTD., TIRUPATI, is “ONE and ONLY” company got success in giving commercial mass production of selected TEAK CLONES. Hence, dear intellectuals, please think about the facts and come to take an ideal decision in selection of our “SHILP” produced suitable and perfect TEAK CLONES for your planting programmes. Our “SHILP” productions of Andhra Pradesh Forest Department identified and some other important TEAK CLONES
