Crop physiology deals with the study of how crop plants develop, grow, and respond to their environment at the cellular and biochemical level. It examines topics like seed physiology, optimal seedling growth, plant population, harvest index, the mode of action of herbicides, nutriophysiology, photoperiodism, plant growth regulators, water use efficiency, and post-harvest physiology. Understanding crop physiology is important for agriculture as it allows for improving areas like withstanding biotic and abiotic stresses, maximizing yields, and reducing post-harvest losses in India's predominantly rainfed agricultural system.

The document discusses plant disease forecasting. It provides information on:
1. The principles of disease forecasting are based on the nature of the pathogen, environmental effects on pathogen development, host response to infection, and grower activities.
2. Models for disease prediction include empirical, simulation, and general circulation models, but these models have limitations due to uncertainty and non-linear relationships.
3. Disease forecasts are used for strategic decision making like crop selection and tactical decisions around disease management measures. Successful forecasting requires reliability, simplicity, importance of the disease, and usefulness.History of plant pathology

Plant pathology is the study of plant diseases. It deals with the causes and mechanisms of disease development, plant-pathogen interactions, and disease management methods. Some key events in the history of plant pathology include the first use of microscopy to observe fungi and bacteria in the 16th-17th centuries, the 19th century discoveries of the fungal causes of late blight and anthrax, and the early 20th century discoveries of viral and other non-fungal pathogens. Modern plant pathology incorporates genetics, microbiology, and other fields to understand and address important diseases.B.sc. agri sem ii agricultural microbiology unit 4 biopesticides

The document discusses plant growth promoting rhizobacteria (PGPR) and their mechanisms for promoting plant growth and providing disease resistance. Some key points:
1) PGPR colonize the rhizosphere and rhizoplane of plant roots in higher numbers than other soil regions. They can fix nitrogen, produce plant hormones, and positively influence plant growth and health.
2) Mechanisms of PGPR include producing compounds like phytohormones, organic acids, siderophores, fixing nitrogen, solubilizing phosphate, and antibiotics. They also compete with deleterious microbes and induce systemic resistance in plants.
3) PGPR provide disease resistance to plants through mechanisms like competition with pathogens, antibiotic productionMilestones in the history of plant pathology

This document discusses plant disease development. It begins by outlining the objectives and topics to be covered, which include the disease triangle, factors for successful disease development, and stages of disease development. The disease triangle requires the presence of a susceptible host, virulent pathogen, and favorable environment. The factors for disease development include the properties of the pathogen, host, and environment. The stages of disease development are inoculation, penetration, infection, growth and reproduction of the pathogen, and dissemination of the pathogen.Effect of environment and nutrition on plant disease development

Citrus Greening Disease, also known as Huanglongbing (HLB), was first found in Florida in August 2005. It is a disease spread by the Asian citrus psyllid that infects citrus trees and eventually kills them. HLB has had severe economic impacts on Florida's citrus industry by reducing yields, increasing production costs, and requiring the removal of infected trees. Management of HLB is challenging as there are few effective treatment options and the disease and its vector have continued to spread rapidly throughout Florida's citrus-growing regions since being detected.Plant pathogenic Bacteria

It is generally survive in soil and dead and decay organic matters and spread by water, agricultural implements, propagating materials, insects and humans. Hence, management practices are designed accordingly. Crop rotation, field sanitation, disinfestation of agricultural implements, use of disease free or resistant varieties and use of antibiotics are few of them.Pollination : Types and significance

The Seminar presented by Biswajit Das
L.T.K. College, Department of Botany.
In order that a plant is able to produce seeds, the male and female gametes must come together.
The male gamete is produced by the androecium within the pollen grain, while the female gamete is produced by the gynoecium within the ovule.
Pollination油is the process that helps in bringing male and female gametes together.
Self-pollination and cross-pollination are two major ways. Flowering plants are adapted to use vivid agents, like biotic and abiotic.

Bacterial canker, also known as gummosis, is caused by the bacterial pathogens Pseudomonas syringae pv. syringae and P. syringae pv. persicae. It affects stone fruits like plum, cherry, apricot, peach and ornamental Prunus species. Symptoms include sunken areas on stems, spurs and leaves developing brown spots that fall out. Management strategies include using resistant rootstocks and cultivars, maintaining tree health, pruning in early summer, and applying copper-based sprays in autumn and spring. Chemical control relies on fixed copper or Bordeaux mixture applications.Introduction importance scope and objectives of plant pathology

This document discusses the infection, invasion, growth, and reproduction of plant pathogens. It describes how pathogens infect plants through various means such as intracellularly or intercellularly. Successful infections result in symptoms. The incubation period is the time between inoculation and symptom appearance, which depends on factors like the pathogen-host combination and environment. Pathogens invade tissues and spread systematically or locally within the plant. They continue growing and branching out indefinitely. Pathogens reproduce through various means like spores, fission, or eggs. Reproduction rates vary greatly between pathogen types but large numbers can be produced rapidly, facilitating widespread infection.downy mildew(bajra),root knot(mulberry)

Root knot nematodes belong to the class nematode, order tylenchida, and family heteroderidae. They are commonly found in sandy soils under irrigated conditions. Infected mulberry plants show stunted growth, marginal leaf necrosis, yellowing leaves, and characteristic knots on roots. As a result of poor growth, about 10-12% of leaf yield is lost along with reduced leaf quality.

2. Seed germination, root and shoot growth, and biomass were measured after treating seeds and seedlings with 0.1% or 1% extracts of mesquite litter incubated for 1-7 days.
3. Most treatments showed comparable or better seed germination and seedling growth than the control, suggesting that mesquite litter extracts at these concentrations may not inhibit and could even promote rice growth under certain conditions.Assessment of effect of prosopis juliflora litter extract on seed germination...

Plant tissue culture is the process of growing plant cells, tissues or organs in vitro under sterile conditions on a nutrient medium. The father of plant tissue culture was Haberlandt who first conceived of culturing plant cells aseptically in 1902. There are two main types of growth in tissue culture - organized growth where structure is preserved, and unorganized growth like callus or cell suspension cultures which lack structure. Key steps in establishing tissue cultures include selecting an explant, surface sterilization, and culturing on solid or liquid media. Plant growth regulators like auxins and cytokinins are important for directing growth. Tissue cultures are used to produce valuable secondary metabolites like taxol through optimization of culture conditions and addition of elicPlant biodivercity

Horticulture, often confused with botany, is a specialized branch of agricultural science that focuses on the cultivation and management of plants. While both horticulture and botany involve the study of plants, there are distinct differences between the two disciplines. Horticulture primarily deals with the practical aspects of plant cultivation, including plant breeding, production, and landscape design. On the other hand, botany is a broader field that encompasses the scientific study of plants, including their physiology, taxonomy, and evolution. For more information visit our website.
