Variation in growth traits of Acrocarpus fraxinifolius Wight & Arn. populations in Southern Karnataka. Ashwath M. N.*, Satish B. N., G. M. Devagiri, R. K. Hegde and Hareesh, T.S. * Corresponding author: ashumangalapare97@gmail.com ABSTRACT: The present investigation was carried out to quantify the variation in growth characters of Acrocarpus frax...

The study was conducted to compare the wood parameters among nine populations of Acrocarpus fraxinifolius from Southern Karnataka. To understand the variation, three trees from each population were selected and different wood properties, viz., bark-thickness, wood density, specific gravity, fibre parameters and vessel parameters, were analysed. The...

The purpose of this study was to understand the effect of controlled circumstances and exogenous hormones on epicormic shoot development and rooting ability of teak epicormic shoots obtained from teak branch cuttings. The growing conditions had an effect on physiological and shoot quality parameters with an average of 8 to 10 harvestable shoots per...

Analysis of natural diversity in wild/cultivated plants can be used to understand the genetic basis for plant breeding programs. Recent advancements in DNA sequencing have expanded the possibilities for genetically altering essential features. There have been several recently disclosed statistical genetic methods for discovering the genes impacting...

Biopriming of seeds is an innovative approach that combines microbial inoculation with seed hydration. It has become a potent technique to enhance seed quality and crop resilience to climatic aberrations. Coating seeds with microorganisms like Trichoderma, Pseudomonas fluorescens, and other plant growth-promoting rhizobacteria (PGPR) enhances germi...

Deadwood dynamics presumes prime significance in several aspects varying from enriching forest soil nutrients, micro/macrofaunal diversity, protective soil cover, and microhabitat to a remarkable role in mitigating climate change. Several extrinsic and intrinsic factors regulate the process of production, fall, and decay of deadwood. Among intrinsi...

The present study focuses on understanding the genetic diversity among the selected teak accessions using Inter simple sequence repeat (ISSR) markers. Genomic DNA from ten selected teak accessions was extracted using a modified Cetyltrimethylammonium Bromide (CTAB) protocol, ensur-ing high quality and yield. ISSR primers were employed to amplify DN...

Drought stress is a critical abiotic factor limiting plant growth and productivity, particularly in tropical forestry species such as Swietenia macrophylla . This study investigates the physiological, biochemical, and proteomic mechanisms underlying drought tolerance in mahogany seedlings and evaluates the efficacy of Jasmonic Acid (JA) and Salicyl...

Drought stress is a major abiotic constraint affecting growth and productivity in tropical forestry species such as Swietenia macrophylla (mahogany). This study investigates the morphometric, physiological, biochemical, and proteomic responses of mahogany seedlings to drought and evaluates the ameliorative potential of two defense hormones—Jasmonic...

Tree improvement is aimed at excelling genetic makeup and productivity of trees to meet the evolving ecological and economic demands. Though conventional tree improvement techniques have served better, however, their intrinsic limitations impede further progress. Biotechnology tools offer a revolutionary path forward in tree improvement, addressing...

Bamboo, commonly known as "Green Gold" or "Poor Men's Timber," is an arborescent grass belonging to the Poaceae family. It is continuously gaining attention due to its diverse life forms, flowering patterns, and multipurpose utilities. Bamboos are cosmopolitan in distribution, widely adaptable, and growing naturally in Asia's tropical, subtropical,...

Climate change poses severe challenges to ecosystems, agriculture, and forestry by intensifying extreme weather events like droughts, floods, and heat waves, compromising plant health, productivity, and ecosystem stability. In response to these stresses, plants activate intricate defense mechanisms that mitigate damage and facilitate adaptation...

Casuarina equisetifolia L., commonly called whistling pine, is an economically and industrially important tree species with global significance. Although species possess versatile importance worldwide, efforts imparted for selection and designing a robust model of selection index are inadequate. The selection process, based on quantitative and qual...

Trees are essential for global biodiversity, pollution reduction, and mitigating the effects of climate change, as well as an alternative source of bioenergy. They provide timber and with the rise of the population, the demand has been increased for large-scale production. The conventional multiplication of forest trees through seed and cuttings fa...

In the context of increasing climatic variability, it is important to find ecologically and financially viable coping strategies for farmers who have less access to technological improvements. Agroforestry assumes considerable significance in this pursuit on account of their unique potential for the modulation of microclimate by trees which is impo...

Agroforests are intricate systems whose management relies on copious interactions among their components. Complex interactions between trees, crops, soil, and climate have a significant impact on the productivity of agroforestry systems. The system’s overall sustainability and yield are determined by its management and the harmony between positive...

Mimusops elengi L., (bullet wood) belongs to the family Sapotaceae and is a native tree species of Western Ghats, India. It is well known for its fruit, and fodder and is grown as an ornamental tree. Various parts of the tree are utilized in traditional medicinal practices. In this species, seed germination is rather difficult without pre-seed trea...

Teak (Tectona grandis L.f.) is the well-known tropical timber species to meet the demand of wood-based industries. Choosing superior parents and developing technologies for its vegetative propagation is essential for promising better growth and yield. Production of epicormic shoots on live detached branches under high humidity and temperature, is a...

Crop improvement programmes began with traditional breeding practices since the inception of agriculture. Farmers and plant breeders continue to use these strategies for crop improvement due to their broad application in modifying crop genetic compositions. Nonetheless, conventional breeding has significant downsides in regard to effort and time. C...

“Anthropocene epoch” is an unofficial unit of geological time which resulted due to insignificant effects of human activities on the climate and ecosystems. Term resilience denotes the capacity to withstand adversity and recover quickly from difficult events such as climate change and ecological imbalance. In this climate change scenario, maintaini...

Invasive plant species are considered one of the important threats to global biodiversity. Lantana camara L. is an alien invasive species spread across India. The spreading patterns of Lantana indicate a serious threat to native plant biodiversity and regeneration. The present study was carried out to assess the effect of Lantana invasion on natura...

Southern India (SI) is bestowed with several threatened and near threatened (TNT) underutilized edible fruit species (UEFS) that contributes to food and nutritional security, particularly to the indigenous people. Unfortunately, information related to these natural products is fragmentary and least researched. The PRISMA Protocol was used to conduc...

Gloriosa superba L. (family Colchicaceae or Lilliaceae) is a perennial tuberous climbing herb, extensively scattered in tropical parts of Asia and Africa.
