Thesis Abstract

Abstract
This thesis investigates the impact of various light wavelengths on the growth and development of plants. Light is an essential factor in photosynthesis and plays a crucial role in plant growth processes. Different light wavelengths have been shown to influence various physiological and developmental aspects of plants. The primary objective of this study is to explore how different light wavelengths, including red, blue, and green light, affect the growth, morphology, and biochemical composition of plants. Chapter One provides an introduction to the research topic, detailing the background of the study, the problem statement, objectives, limitations, scope, significance, structure of the thesis, and definitions of key terms. Chapter Two presents a comprehensive literature review, examining previous studies on the effects of light wavelengths on plant growth and development. Chapter Three outlines the research methodology, including the experimental design, plant materials used, light sources, growth conditions, and data collection methods. The chapter also discusses the statistical analysis employed to interpret the results effectively. Chapter Four presents a detailed discussion of the findings, analyzing the effects of different light wavelengths on plant growth parameters such as leaf area, biomass accumulation, chlorophyll content, and photosynthetic efficiency. The chapter also explores the biochemical changes induced by specific light wavelengths, including alterations in secondary metabolite production and antioxidant activity. Chapter Five concludes the thesis by summarizing the key findings, discussing their implications for plant growth and development, and suggesting areas for future research. The study contributes to the understanding of how light quality influences plant physiology and provides valuable insights for optimizing growth conditions in controlled environments such as greenhouses and growth chambers. In conclusion, this thesis highlights the importance of considering light quality as a critical factor in plant growth and development. By elucidating the effects of different light wavelengths on various aspects of plant physiology, this study enhances our knowledge of plant responses to environmental cues and offers practical implications for improving crop production and plant cultivation strategies.
