Indie są obdarzone kilkoma strefami agroklimatycznymi sprzyjającymi produkcji wrażliwych i delikatnych produkt w kwiaciarskich. W ciągu dziesięciu lat po liberalizacji przemysl kwiaciarski poczynil ogromne postępy w dziedzinie eksportu. Okres ten charakteryzowal się dynamicznym przejściem od produkcji na wlasne potrzeby do produkcji komercyjnej. Tithonia rotundifolia Blake jest jedną z takich atrakcyjnych roślin jednorocznych o dużych, efektownych, dlugich kwiatostanach i pojedynczych kwiatach. Pomimo pięknych kwiat w ozdobnych, nie jest ona w og le spotykana na rynku komercyjnym. Ponadto nie zbadano jeszcze okresu przydatności tej rośliny do spożycia. W związku z tym uznano za konieczne przeprowadzenie niniejszych badań w celu zbadania zmian zachodzących podczas procesu starzenia się, a także podczas okresu przydatności do spożycia po zbiorach tak ważnej potencjalnej rośliny ciętej. Żywotnośc ciętych kwiat w w wazonie odgrywa istotną rolę w ich akceptacji handlowej, dlatego podjęto pr bę zbadania wplywu r żnych substancji chemicznych zawartych w roztworze do wazon w. Rosnąca wiedza na temat odżywiania roślin mineralami, ze szczeg lnym uwzględnieniem mikroelement w, uświadomila nam, że dzięki rozsądnemu dostarczaniu niekt rych substancji nieorganicznych lub organicznych możliwe są znaczące zmiany.

A Tithonia rotundifolia Blake uma planta anual atraente, com flores grandes, vistosas, com ped nculos longos e solit rias. Apesar de ter uma flor ornamental bonita, n o vista no mercado comercial. Al m disso, a vida til desta flor tamb m ainda n o foi estudada. Consequentemente, sentiu-se a necessidade do presente estudo com o objetivo de estudar as mudan as que ocorrem durante o processo de senesc ncia e tamb m durante a vida til p s-colheita de uma flor de corte t o importante e com tanto potencial. A vida em vaso das flores cortadas desempenha um papel vital na aceitabilidade comercial das flores, tendo sido feita uma tentativa para descobrir a influ ncia de v rios produtos qu micos na solu o do vaso. O conhecimento crescente sobre a nutri o mineral das plantas, com especial refer ncia aos micronutrientes, fez-nos perceber que s o poss veis grandes mudan as atrav s do fornecimento criterioso de certas subst ncias inorg nicas ou org nicas.

Plant breeding is a science of producing desired varieties by exploiting genetic structure of plant applying the principles of genetics, initial work was started quite earlier during initiation of agriculture but in the 19th the century. Gregor Mendel gave the principle of heredity since then major evolution have started in this field. In 20th century this laws were applied for the improvement of plants, through various methods characters such as; disease and insect resistance, heat and drought tolerance, high yield, adaptation are raised. One of the major applications of Plant breeding is it helps to fulfill global food security. This book contains information about the plant breeding, its methods, application, history, aim, objectives, hybridization methods, pollination methods etc. which helps us to manipulate genetic structure of plant or crops. Book carry vital information regarding certain important topics related to plant breeding and their easy understanding and to the point information is provided. This book has been illustrated with plant breeding topics which are covered with colored photographs, tables which are presented in new style and format.

In the last decade, different approaches have been used to mitigate soil contamination, however many factors can affect the success of any remediation method including soil heterogeneity and the contaminant type. Phytoremediation which involves the interaction of plant roots and associated rhizospheric microorganisms for the remediation of soil and water contaminated with high levels of metals, pesticides, solvents, radio nuclides, explosives, nutrients, crude oil etc. 'PHYTO' presents the concepts and application of phytoremediation and phytotechnology in one comprehensive guide, illustrating when plants can be considered for the uptake, removal or mitigation of on-site pollutants on a range of landscapes such as brownfields, landfills and military sites. Current scientific case studies are covered, highlighting the advantages and limitations of plant-based cleanup. Phytoremediation asa remediation technology that has been receiving attention lately as the results from the field trials indicate a cost saving compared to conventional treatment. This work also be used to help guide research, develop and regulation. Areas of needed research have been identified.
