Foliar Action
Leaf it Right There
100
The cementing material between cells (concentrated in middle of lamella)
Lignin
100
Average rate of decay per year
6-8 cm/yr
100
Fruiting bodies, swollen knots and resinosis, basal fire scars, are all examples of these signs of decay
Macroscopic Signs
100
The fungal class of most foliar diseases
Ascomycete
100
This needle blight has a worldwide distribution, high-risk in low-lying lands, distributed by rain splash and air dispersal of spores, in the early summer, needles show yellow-tan spots that turn to reddish-brown bands, which girdle the needle
Dothistroma Needle Blight
200
Primary cell wall constructed of cellulose molecules
Microfibrils
200
The age in which volume added by growth = volume lost to decay merch volume is maximized
Pathological Rotation
200
Fungus Mycelium (hyphae without clamp connections)
Basidiomycetes
200
Characteristic powdery, white mycelium on the leaf surface, can effect the flower, leaf, and green stem tissues
200
Major host Lodgepole pine, has a one year life cycle, dispersed needles on previous years growth are shed as the summer progresses and remaining new growth has a lion's tail appearance
Pine Needle Cast
300
Removal of cell wall constituents at variable rates
Selective Delignification
300
Where two organisms meet and they will cause each other to stop growing
Antagonism
300
Hyphae without clamp connections
Ascomycetes
300
all begin as leaf spots, but continue spreading down leaf veins, into the petiole, and into the woody tissue of the plant
Leaf Blight
300
Major hosts, all conifers in BC, Snowbelt/higher elevations, masses of mycelium cover branches and twigs buried under the snow
Brown Felt Blight
400
Extracellular enzymes that degrade cellulose and hemicellulose
Cellulases
400
CODIT
Compartmentalization of Decay in Trees
400
This rot effects conifers and hardwoods, perennial pored fruiting body.
Brown Cubical Rot
400
Parasite, but saprophyte occasionally --> Most Root Rots
Facultative Saprophyte
400
Can spread sexually, asexually, and by vectors (aphids and sucking insects)
Powdery Mildew
500
Depolymerizing enzyme called lignin peroxidase degrades this wood structure
Lignin (Degradation)
500
Is a bladder like distension or outgrowth, of a parenchyma cell into the lumen of adjacent xylem vessels in wood
Tyloses
500
The process in which white rot can only degrade lignin and not much cellulose
Biopulping
500
A dense mass of hyphae that is produced by certain fungi and gives rise to spore-producing bodies
500
Result in the death and shedding of dead needles
Needle Casts
