It Provides Perspectives in Plant Sciences in India as Reflected through contents of thirty selected Papers by Expert botanists who participated in different symposia or focal theme lectures organised in the section of Botany during platinum Jubilee session of Indian Science congress held at pune from January 7-12, 1988. the topics covered pertain to themes of basic and applied nature of great value in the emerging frontiers of plant science research in india. these represent the present and future trends in researches in the country and reflect the 'state of art' status.The contents concern nearly all chosen fields of botanical research. Thus,the book should be of great value to: (i) Students of botany at all levels of research in India,and (ii) Scientific planners in the country.It would also find its use with plant scientists on international scene because of views expressed on certain basic and applied concepts.
The Volume Contains Papers Presented At The International Symposium On Phycology Ogranized As Part Of Prof. M.O.P. Iyengar Centenary Celebration The University Of Madras, Indian National Science Academy, Council Of Scientific And Industrial Research, Asia Network Of Biological Sciences, Committee Of Biological Sciences, Committee Of Science And Technology For Develping Countries.The delebrations were divided in 5 groups namely: classification of algae,algae in freshwater ecosystem marine algae-their productivity and utilization fossil diatoms and biostratigraphy,Algal biofertilizers and terrestrial ecosystems.

Roots Metal Pollution due to various Industrial and agricultural activities is causing serious threat both to terrestrial and aquatic ecosystems. Some of these Metals are essential as trace elements but they become toxic when their concentration exceeds certain level. Certain microbes and Plants detoxify metabolically such pollutants and may reduce the vulnerability of such heavy metals. Various anthropogenic activities like mining, smeltering, disposal of wastes excessive use of Pesticides and Fertilizers etc. enhance the metal toxicity affecting the growth and Productivity of Agriculture and forestry.
In recent past heavy metal toxicity has been studied at genetic, biochemical, Physiological and Molecular levels both in laboratory and in contaminated environment. Mycorrhiza, ubiquitous symbiotic association between Fungi and Roots of Higher plants constitute an important functional component of Soil ecosystem. The Positive role of mycorrhiza in nutrient uptake and Improving Crop has shown that mycorrhizal fungi also improve tolerance of plants to heavy metals and provide them better support to overcome abiotic stress caused by heavy metals. This book provides critical Research analysis on the role of mycorrhiza on microbial enzymes, improvement of growth of seedling under heavy metal polluted soil and the possible mechanism of detoxification of heavy metals by microbes, mycorrhiza and plants.
We are quite hopeful that book will be very useful to the teachers, researchers and post-graduate students involved in studies related to agriculture, forestry, botany, Environmental sciences and microbiology.

GRAIN early Neandethal man, weeds have been Used for food, feed and Healing purposes. The Knowledge on the subject has descended through generations and has survived through Times among some of the primitive tribal people. Ethnobotany in a specialised branch of Botany that deals with food, feed, Medicinal and other were of wild Plants and weeds. In olden days, the subject of human suffering and its alleviation was closely also dated with religion, Magic and myth. Though ancient knowledge is valuable but need to by scientifically tested.
The book covers more than one hundred seventy herbs, most of which are readily available in Paddy Fields and bunds. It describes the food, feed pharmacentical and other uses of Rice Weed found in arable, swampy, shallow water, deep Water ecosystems. The distinchre feature of the book is its reasonably comprehensive information about the habit, habitat, morphological description, occurrence and ethnobiological value of prominent weeds present in South Asia.
It is an indispensable book for every researcher, teacher, planner, and students to strengthen the Agriculture and food security. Based on his own work over the number of years and that of others before him, The Author presents in this book ethnobiological value of rice weeds in Asia with illustrations. The book fulfills a long-felt need of ethnobiology of rice weeds in Asia.
