The Impact

Drought stress is creating dangerous situation worldwide. The impact of stress is not only the deficiency of water but it also leads to the deficiency and losses of everything which are linked to the water resources directly or indirectly. Drought stress disturbs the normal biochemical, molecular and physiological processes, affecting the morphology of plant. As a result the plant is either unable to live on abrupt changes or learn to avoid/tolerate the variation in the environment. The results vary species to species depending on genotype, frequency and time period of drought stress. There is need of screening various tree species for getting information related to their ability and capacity level of susceptibility, tolerance and avoidance behaviour with the further goal of their plantation in the various nurseries in order to rehabilitate the drought prone areas, wastelands and to increase intangible and tangible benefits.

Future Studies

Phenolic metabolites are frequently implicated in chemical defense mechanisms against pathogens in woody plants. However, tree breeding programmes for resistance to pathogens and practical tree-protection applications based on these compounds seem to be scarce. To identify gaps in our current knowledge of this subject, we explored some of the recent literature on the involvement of phenolic metabolites in the resistance of northern forest trees (Pinus, Picea, Betula, Populus, and Salix spp.) to pathogens. Although it is evident that the phenolic metabolism of trees is often activated by pathogen attacks, few studies have convincingly established that this induction is due to a specific defense response that is capable of stopping the invading pathogen. The role of constitutive phenolics in the resistance of trees to pathogens has also remained unclear. In future studies, the importance of phenolics in oxidative stress, cell homeostasis and tolerance, and the spatial and temporal localization of phenolics in relation to invading pathogens should be more carefully acknowledged. Possibilities for future studies using advanced methods (e.g., metabolic profiling, confocal laser scanning microscopy, and use of modified tree genotypes) are discussed.

Plant Seedlings

Seedlings are the first step in providing ready-to-plant seedlings and supporting sustainable forest-building processes. Growth of good quality tree, required seeds healthy, superior and free from pests and diseases in the nursery area. Lack of information on the types of pests and diseases that attack plants in the nursery at PT. Sari Bumi Kusuma KM. 93, it is necessary to identify clearly in order to know the types of pests and diseases that attack and further control measures against pest and disease attacks. Pests are all animals that cause losses to forest trees and forest products such as insects, squirrels, rats, pigs, deer and others. But the reality in the field of potential and explosive pests cause losses is from the insect class. Illness is the deterioration of physiological processes caused by a continuous pressure or disorder of a major (biotic or abiotic) cause that cell or tissue activity becomes abnormal, which is described in a typical pathology form called a symptom or sign. It is these symptoms or signs that indicate whether the tree in the forest is healthy or sick. The pest was found are caterpillar, looper and grasshopper leaves. The deaseas are trunk cancer, fruit tumor, leaves spott, gaal and fungi.Keywords: Nursery, pests, diseases.

Atpase Localization

Adenosine triphosphatase (ATPase) activity has been shown to be associated with numerous physiological processes in both plants and animal cells. Biochemical studies have shown that in higher plants ATPase activity is high in cell wall preparations and is associated with the plasma membrane, nuclei, mitochondria, chloroplasts and lysosomes. However, there have been only a few ATPase localization studies of higher plants at the electron microscope level. Poux (1967) demonstrated ATPase activity associated with most cellular organelles in the protoderm cells of Cucumis roots. Hall (1971) has demonstrated ATPase activity in root tip cells of Zea mays. There was high surface activity largely associated with the plasma membrane and plasmodesmata. ATPase activity was also demonstrated in mitochondria, dictyosomes, endoplasmic reticulum and plastids.
