    BIL 161: Environment and Development: The Effects of Environmental Variables on Seed Germination The seed is more than just a plant waiting to happen. It is a complex marvel of evolution, a miniature life-support system that responds to environmental cues in order to give the embryo nestled within the best chance of survival. I. Characteristics and Classification of Plants Plants share synapomorphies that set them apart from other organisms. 1. true tissues (of types unique to plants) 2. waxy cuticle (to prevent desiccation) 3. stomates (microscopic gas exchange pores on the leaves) 4. apical meristems (permanent embryonic tissue for constant growth) 5. multicellular sex organs (male antheridia and female archegonia) 6. walled spores produced in structures called sporangia 7. embryo development inside the female parent 8. secondary metabolites (alkaloids, tannins, flavonoids, etc.) 9. heteromorphic alternation of generations The most primitive plants do not produce seeds at all, but rather release spores into the environment where they grow into a second life cycle stage, called the gametophyte. In seed plants, the life cycle is highly derived. Seed plants still make spores, but each spore grows into a gametophyte that is little more than a bit of tissue that gives rise to gametes. In the male parts of the plant, each spore develops into a sperm-producing male gametophyte known as pollen. In the female parts of the plant, meiosis occurs inside a structure known as the ovule, which will eventually give rise to the seed. Plants can broadly be classified as follows. A. Bryophytes – non-vascular plants (mosses, liverworts and hornworts) B.

    1 Principles of Plant Pathology Path

    PRINCIPLES OF PLANT PATHOLOGY PATH 271 (1+1) Prepared By DR. P. KISHORE VARMA, ASSISTANT PROFESSOR, DEPARTMENT OF PLANT PATHOLOGY AGRICULTURAL COLLEGE, ASWARAOPET 507 301 1 LECTURE 1 INTRODUCTION TO PLANT PATHOLOGY Why Plant Pathology? Plants are essential for maintenance of life. Plants not only sustain the man and animals, they are also the source of food for multitudes of micro-organisms living in the ecosystem. Thus, while man has been able to subjugate plants and animals for his own use, the competing micro-organisms still defy his efforts and claim a major share of resources which man would like to use for himself. It is in this context that the need for fighting the competing micro-organisms and other agencies that lack loss of productivity has been felt. The attack on plants by these micro-organisms changed the appearance and productivity of the crop and this observed change was called a disease. Plant diseases have been considered as stubborn barriers to the rapid progress of food production. We call a plant healthy only so long as it continues to perform all its normal physiological activities and give the expected yield according to its genetic potentiality. Physiological activities of a healthy plant 1. Normal cell division, differentiation and development. 2. Uptake of water and nutrients from the soil. 3. Synthesis of food from sunlight by photosynthesis. 4. Translocation of water and food to the sites of necessity through xylem and phloem. 5. Metabolism of synthesized material 6. Reproduction A diseased plant fails to perform one or more of these functions.

    Plant-Parasitic Algae (Chlorophyta: Trentepohliales) in American Samoa1

    Plant-Parasitic Algae (Chlorophyta: Trentepohliales) in American Samoa1 Fnd E. Erooks 2 Abstract: A survey conducted betweenJune 2000 and May 2002 on the island of Tutuila, American Samoa, recorded filamentous green algae of the order Tren­ tepohliales (CWorophyta) and their plant hosts. Putative pathogenicity of the parasitic genus Cephaleuros and its lichenized state, Strig;ula, was also inves­ tigated. Three genera and nine species were identified: Cephaleuros (five spp.), Phycopeltis (two spp.), and Stomatochroon (two spp.). A widely distributed species of Trentepohlia was not classified. These algae occurred on 146 plant species and cultivars in 101 genera and 48 families; 90% of the hosts were dicotyledonous plants. Cephaleuros spp. have aroused worldwide curiosity, confusion, and con­ cern for over a century. Their hyphaelike filaments, sporangiophores, and as­ sociated plant damage have led unsuspecting plant pathologists to misidentify them as fungi, and some phycologists question their parasitic ability. Of the five species of Cephaleuros identified, C. virescens was the most prevalent, followed by C. parasiticus. Leaf tissue beneath thalli of Cephaleuros spp. on 124 different hosts was dissected with a scalpel and depth of necrosis evaluated using a four­ point scale. No injury was observed beneath thalli on 6% of the hosts, but full­ thickness necrosis occurred on leaves of 43% of hosts. Tissue damage beneath nonlichenized Cephaleuros thalli was equal to or greater than damage beneath lichenized thalli (Strig;ula elegans). In spite of moderate to severe leaf necrosis caused by Cephaleuros spp., damage was usually confined to older leaves near the base of plants. Unhealthy, crowded, poorly maintained plants tended to have the highest percentage of leaf surface area affected by TrentepoWiales.

  • Classification of Botany and Use of Plants

    Classification of Botany and Use of Plants

    SECTION 1: CLASSIFICATION OF BOTANY AND USE OF PLANTS 1. Introduction Botany refers to the scientific study of the plant kingdom. As a branch of biology, it mainly accounts for the science of plants or ‘phytobiology’. The main objective of the this section is for participants, having completed their training, to be able to: 1. Identify and classify various types of herbs 2. Choose the appropriate categories and types of herbs for breeding and planting 1 2. Botany 2.1 Branches – Objectives – Usability Botany covers a wide range of scientific sub-disciplines that study the growth, reproduction, metabolism, morphogenesis, diseases, and evolution of plants. Subsequently, many subordinate fields are to appear, such as: Systematic Botany: its main purpose the classification of plants Plant morphology or phytomorphology, which can be further divided into the distinctive branches of Plant cytology, Plant histology, and Plant and Crop organography Botanical physiology, which examines the functions of the various organs of plants A more modern but equally significant field is Phytogeography, which associates with many complex objects of research and study. Similarly, other branches of applied botany have made their appearance, some of which are Phytopathology, Phytopharmacognosy, Forest Botany, and Agronomy Botany, among others. 2 Like all other life forms in biology, plant life can be studied at different levels, from the molecular, to the genetic and biochemical, through to the study of cellular organelles, cells, tissues, organs, individual plants, populations and communities of plants. At each of these levels a botanist can deal with the classification (taxonomy), structure (anatomy), or function (physiology) of plant life.

    Etiology,Loss, Symptoms and Control of Diseases

    Phytopathology is a branch of Botany that deals with causal organism,etiology,loss, symptoms and control of diseases. ETIOLOGY:-Science of cause of disease. Pathology (Greek word‘Pathos’ and ‘Logos’.) Pathos =Suffering Logos=Study “Study of Plant Sufferings” Or “Study of Plant Diseases”. FATHER OF PLANT PATHOLOGY- ANTON de Bary. Aims of plant pathology } To make a survey of the living as well as non- living causes of the diseases. } To study the different types of mechanisms by which the diseases are developed in plants. } To elucidate the interaction mechanism among plants,pathogen and the environment. } Minimize the loss of useful plants through application of the principles of plant disease prevention. } To prevent plant disease epidemics or to delay their onset until the harvest time is over. DISEASE Disease in a plant involves a number of harmful Physiological processes which leads to a lot of irregularities in the morphology and anatomy of the host. SYMPTOMS The altered and disadvantageous differences of the host from the normal plant are referred to as Symptoms of the disease. 1. Host : An organism that harbours or supports the activities of a parasite . 2.Suscept :An organism that is susceptible or prone to disease. 3.Susceptibility :It is the inability of a plant to resist the effect of a pathogen or any other damaging factor. 4.Parasite :It is an organism or virus existing in an intimate association with another living organism from which it derives an essential part of the materials for its existance. 5.Pathogen :A pathogen is an organism or virus capable of causing disease in a particular host.
