An outbreak of a new canker and dieback disease was recorded in Acacia nilotica seedlings. The causal organism was identified as Fusarium lateritium f. sp. acaciae f. sp. nov. and perithecial stage belongs to Gibberella. The disease was controlled by three sprays of mixture of Carbendazim and Copper oxychloride and mixture of Carbendazim and Dithane M-45.- Vulture Sightings at Corbett Tiger Reserve, Uttaranchal

To know the genetic worth of the plus trees and association among different traits, one year old half-sib progenies of 48 plus trees were evaluated at Nauni during the year, 2000. Highly significant variation in all the traits was noted except for number of stomata. Studies on genetic coefficient of variation, heritability and genetic advance showed that a large portion of phenotypic variability was genetic and highly heritable for the total chlorophyll content, needle diameter and needle cross-sectional area. High heritability estimates were accompanied with high genetic gain for total chlorophyll content and needle cross-sectional area, suggesting the additive gene control for the inheritance of these traits. Collar diameter showed positive and highly significant correlation with seedling height and needle length.- Provenance Variation in the Specific Gravity of Wood of Chir Pine

Provenance variation in specific gravity of wood of 23 provenances of Chir pine (Pinus roxburghii Sarg.) belonging to 4 States viz. Himachal Pradesh, Jammu &Kashmir, Uttar Pradesh (now in Uttaranchal) and Arunachal Pradesh covering the geographical range between 27ο30' N to 35ο N, Longitude 75ο 20' E to 92ο 30' E and altitude 575 m to 2,200 m has been reported. These studies were carried out on 16-years-old trees growing in a field trial laid out under Indo-Danish Project on Seed Procurement and Tree Improvement (lDPSPTI) in 1981 at New Forest Campus, Dehra Dun, (Alt. 640m Lat. 30ο 20' 40ο N, Long. 78ο 0' and R.F. 216 cm).

The paper summarizes the results of ischolar_maining of juvenile cuttings of Chir Pine (Pinus roxburghii Sarg.). Cuttings emanating from 9 clones of P. roxburghii. (UPTSB-14 (Bhasla), HPSNR-5 (Nurpur), UPBER-5 (Berinag), UPKAL-10 (Kaligarh), UPPAT-I094 (Patwadangar), UPTSS-3 (Sikanderdbarl, UPDNH-770 (Dhanari), UPBER-368 (Berinag) and UPDNH-81 (Dhanari) were treated with different concentrations of IBA viz. 1000 ppm, 2000 ppm, 3000 ppm and 4000 ppm and planted in vermiculite under mist condition. Significant differences in ischolar_maining percentage and other ischolar_main parameters were observed between the clones. Among the four concentrations of IBA tried, 4000 ppm proved to be the best. 100% ischolar_maining was observed in three clones viz. UPTSB-14, UPKAL-10 and UPPAT-1094.- Population Dynamics of Arbuscular Mycorridzal Fungi in Dalbergia sissoo Roxb

Highly wavy grained wood of Red Sanders fetches fabulous prices in the export market, particularly Japan. While the straight grained or normal grained is sold at a very cheap rate. Hence, to increase the frequency of highly wavy grained trees it is necessary to multiply them for large scale plantations, directly or indirectly. A method has been suggested to identify the highly wavy grained plants at nursery stage.- Use of Coppice Shoots in Seed Production Areas of Teak : a New Concept

Creation of seed production areas is an important step in the Tree Improvement Programme for the interim supply of superior seed for afforestation till the seed orchards become fully productive. In Teak seed production areas the production of seed is not only insufficient but its collection is also difficult and expensive. Hence a new approach has been suggested, keeping in view the excellent coppicing capacity of Teak, for higher production of seed per tree and making the collection easier and cheaper.- Effect of Temperature and Relative Humidity on Grafting and Budding of Teak (Tectona grandis Linn.

Cleft grafting and Patch budding are highly successful methods for clonal propagation of Teak provided that work is carried out at 21.3° - 26.3°C temperature and 45.5 -62 per cent relative humidity. Cleft grafting is less economical method in terms of time, material and work as compared to patch budding which is far more easier and cheaper technique. The work is generally carried out in open field condition and for Dehra Dun, April and May were found most suitable period to obtain the maximum success. The percentage of success can be increased by the use of greenhouse or Mist chamber.- Natural Regeneration of Populus ciliata

In forest tree species like Teak, to save time, work on selection of plus trees, establishment of grem plasm banks and creation of seed orchard has to be taken up simultaneously. Genotypic differences, for various parameters, between clones assembled in a first cycle seed orchard create lot of problems and as a consequence seed production is much less than expected. Experiences gained from the model seed orchard of Teak at New Forest, Dehra Dun-first ever seed orcbard in the country - have been presented in this paper to provide information on the performance of various clones to serve as guiding factors for the creation of second cycle seed orchards.- Occurrence of Abnormal Seedlings in Pinus wallichiana AB Jacks; their Significance in Tree Breeding

Characterlstic branchy hablt of cotyledons was observed in seedlings of Pinus wallichiana AB Jacks, a first ever record in tbe Himalayan pine and probably in conifers. Differences between these normal cotyledons wlth ultrastructure studies are highlighted. Also the abnormal seedlings, recovered during germination studies of the seeds obtained from open pollination, are reported under specific beads as 'lethats' and non-lethats'. The present paper reports tbe appearance of abnormal seedlings and discusses probable explanation for their appearance under various experiments. The need of c1assifying these abnormal seedlings is advocated so that uniform terminology can be adopted to ensure tbe morbid types recovend for understanding the reflection of genetic structure of the population.- Teak Plus Trees for Specific Traits

Sandal(Santalum album) can be propagated vegetatively with considerable case. Of the various method described so far vegetative propagation by ischolar_main cuttings under report is easy to perform and results in fair amount of success(i.e. upto 60%). The application of Seradix B2 was advantageous and time of planting also seemed to have some influence, i.e. response from cuttings planted in the first week of April was the best as compared to those planted in May. An interesting feature was the emergence of ischolar_mains from the base of one stem which indicates the possibility of mound layering and ischolar_main krafting also. The minimum time taken for sprouting was recorde as 23 days and for ischolar_main development less than 100 days.- Photoperiodic Response of Pinus patula Schiede and Deppe Seedlings

Pot culture studies were conducted with the seedlings Pinus patula to determine the effect of different photoperiodic treatments on height growth, dry matter production and tracheid characteristics. The three treatments (Long day Short day and Normal day) used in this study have significant effect on all the characters studied. Long day treatment of 18 hours continuous light period has significantly improved height growth and dry matter of both ischolar_mains and shoots of the seedlings. Pronounced differences in tracheid characters such as tracheid length, width, lumen diameter and cell wall thickness have been observed under different photoperiodic treatments.- Studies on Field Grafting and the Growth of the Grafts in Red Sanders
