Seedling establishment is the most critical phase in plant development, making the seedling an important area in basic and applied research. This new graduate-level textbook presents key topics such as different types of germination, the transition from seed to seedling, hormonal regulation of trophisms and morphogenesis and autotrophy acquisition, going on to consider seedling ecology, how seedlings survive in extreme environments and the seedling stage in weeds, agriculture and environmental plants. Written by authors from diverse fields of study and research, this textbook is an essential...

Present study prescribed the potential of varyingly devised osmotic constrains on germination and growth of Parthenium hysterophorus, an alien highly invasive weed species. The effects of differential salinity regimes of three selected salts viz. NaCl, KCl, and MgSO4 were evaluated on germination and growth in lab as well as field trials. Different concentrations of test salts for lab experiments were 10, 20, 30, 40 and 500, 750, 1000, 1250 mM for field experiment.Germination fresh and dry weights of shoot and root as well as leaf area in all treatments were significantly reduced. Likewise,...

This book explores the most important aspects of the biology, ecology and management of -the world's worst weed.- Covering its mode of spread and its impacts upon agricultural production, the environment and human health, it also reviews management techniques such as biological control, cultural, physical, and chemical approaches. Suitable for researchers of plant ecology and related subjects, it also considers the possible uses of Parthenium weed, its distribution and the impacts of climate change.
