Chir pine (Pinus roxburghii Sargent) is a very important indigenous conifer species of lower hills of Himalayas and the Shiwalik mountain range. A request to study the causes of mortality of Chir pine in Morni Forest Range under the Pinjore Forest Division in Haryana was received from the Conservator of Forests and the same have been investigated. It has been observed that the forest tract has been badly abused in past due to high biotic pressure , recurrent fires and heavy resin tapping by French Cup and Lip method. The resin tapping in the said forest has been stopped since 1983. However , the scars of the past injuries have left a permanent mark on these trees , which have over the years and due to recurrent fires lost their viability and have become prone to heavy insect borers infestation. So the immediate cause of current mortality in this area has been found to be the heavy infestation of insect borers. The study showed that these affected trees were severely attacked by four types of insect borers viz. Shpaenoptera aterrima , Cryptorhynchus rufescens , Platypus biformis and Polygrphus longifolia , which badly damaged the bark and bast and girdled the tree. Various insect pest management strategies including the insecticidal application were recommended for protecting the trees from the insect borers and their by protect them from mortality.- Physical and Mechanical Properties of Mangifera indica (Mango) and Syzygium Spp. (Jamun) from Dehra Dun (U.P.)

Based on the tests carried out on small clear specimens, the physical and mechanical properties of Mangifera indica, Dehra Dun (U.P.) and Syzygium spp., Dehra Dun (U.P.) are presented. Nail/screw withdrawal resistance, safe working stresses for structural purposes and suitability indices for different industrial and engineering uses of both the species have also been reported alongwith the corresponding values of Mangifera indica, Puri (Orissa) and Syzygium spp., Cachar (Assam) and also Tectona grandis (Malabar, Nilambur and Coimbatore) for comparison. The results have indicated that properties of both the species viz. Mangifera indica and Syzygium spp. tested from Dehra Dun (U.P.) are inferior in almost all the properties as compared to Mangifera indica, Puri (Orissa) and Syzygium spp., Cachar (Assam).- Ganoderma Root Rot Incidence in an Afforested Stand of Khair (Acacia catechu Willd.) in Lower Siwaliks of Himachal Pradesh

Acacia catechu is a very important and preferred tree species in afforestation programmes in the lower sub-tropical zone of Himachal Pradesh. It is valued for its heartwood, which is used for extracting katha and cutch, ingredients of a number of Ayurvedic and Unani medicines. It suffers serious disease problem in the form of ischolar_main rot by Ganoderma lucidum causing great economic losses. Present paper discusses incidence of Ganoderma ischolar_main rot disease in a khair plantation in lower Siwaliks of Himachal Pradesh. 4.45 per cent tree mortality was recorded which indicated towards an alarming situation. The trees are showing early symptoms of discoloured foliage, trees with stag horn branches and gaps in lines due to removal of dead trees. The inoculum builds up very fast in the area where the sporophores were seen on dead trees, stumps and wood chips in the infected area. Incidence of drying and wilting was more severe in the cultivated portion than the unmanaged part of the land.- Performance of Shisham (Dalbergia sissoo Roxb.) Provenances Against Ganoderma Root Rot

Forty provenances of Shisham (Dalbergia sissoo) were screened against Ganoderma ischolar_main rot under the natural conditions in a randomized block design. Variations to the extent of mortality and plants showing initial ischolar_main rot symptoms were recorded. None of the provenance remained disease free. However, least mortality (2.0%) was recorded in Barielly provenance followed by 4.2 per cent in Rampur provenance and rated as resistant to Ganoderma ischolar_main rot. In the plantation of Rampur and Barielly provenances, 4.2 and 10.4 per cent plants, respectively showed initial symptoms of ischolar_main rot. Highest mortality (33.4%) was recorded in Banaras provenance followed by 29.2 per cent in each Nazibabad and Etawah provenances. In terms of height and diameter, Kankai provenance was rated as best but it was moderately susceptible (14.6% tree mortality) to Ganoderma ischolar_main rot. Provenance Rampur, which was rated as resistant with 2.0 per cent tree mortality, was fifth best in terms of plant height and diameter at breast heightKeywords

Accurate measurement of respiration rate is an important aspect in designing and operating systems such as controlled and modified atmosphere storage that will extend the shelf life of the perishable produce. The respiration rate and respiratory quotient of fresh mature green mango CV. Mallika were determined under closed system at 5, 10, 15, 20, 25 and 33°C (ambient) temperatures. The respiration rate based on carbon dioxide production in aerobic condition decreased about 20 per cent relative to air atmosphere. However, the oxygen consumption sharply reduced to 25-30 per cent relative to air atmosphere at 25°C temperature. The results suggest that, the respiration rate of mango increased with temperature and decrease with storage time. Results of the study can be applied to the MAP design for extending shelf life of mango.Keywords
