Paclobutrazol was applied once in a year 15 October 1997 and 15 September 1998 in soil around the tree canopy spread. Paclobutrazol did not affect on Sugar, pH, Colour, K or glucose-fructose ratio, reduced sugar concentration and did not effect TSS and Firmness of Apple, increased TSS, Ascorbic Acid, Chlorophyll, ß-carotene, amylase, peroxides activity for 12 days in Dashehari Mango in storage at ambient temperature (30-33°C), chemical used Paclobutrazol [(2RS, 3RS)-1-1(4-Chlorophenyl)-4, 4-dimethyl-2-(1,2,4-trizol)-1-yl)] Pentan-3-ethanol.

Biochemical and Biological effects of Kaurene oxidase inhibitor such as Paclobutrazol on vegetative in Mango Cvs. Dashehri, Langra, Chausa and Fazri

Research article of Journal of Plant and Environmental Research Biochemical and Biological effects of Kaurene oxidase inhibitor such as Paclobutrazol on vegetative in Mango Cvs. Dashehri, Langra, Chausa and Fazri Ashok Kumar ¹, С.Р. Singh² and Late Sant Ram³ 1Professor, Uttaranchal college of Agriculture Science, Uttaranchal University, Dehradun-248007, U.K. India.2Professor, Department of Horticulture, G.B.P.U.A&T- Pant Nagar, U.P., India.3Professor, Department of Horticulture, G.B.P.U.A&T- Pant Nagar U.K. India The compound Paclobutrazol [(2RS, 3RS)-1-(4-chlorophenyl)-4, 4-dimethyle-2- (1, 2, 4 Triazol-1-y)] pentan-3-ethanol was the action of this retardants can be antagonized by Gibberellins (GA3) and ent-Kaurenoic acid. The growth regulating properties of paclobutrazol are mediated by changes in the levels of important plant hormones including the gibberellins (GAs), abscisic acid (ABA) and cytokinins (CK). Paclobutrazol (PBZ) affects the isoprenoid pathway, and alters the levels of plant hormones by inhibiting gibberellin synthesis and increasing cytokinins level. When gibberellins synthesis is inhibited, more precursors in the terpenoid pathway accumulate and that resulted to the production of abscisic acid. PBZ has been used to provide plant protection against numerous abiotic stresses such as chilling, water deficit stress, flooding and salinity. Paclobutrazol acts as stress protectant by maintaining relative water content, membrane stability index, photosynthetic activity, and photosynthetic pigments and protects the photosynthetic machinery by enhancing the level of osmolytes, antioxidant activities and level of endogenous hormones and thereby enhances the yield. It is suggested that its main biochemical action is to block the reactions that lead from ent-Kaurene to ent-Kaurenoic acid in the course of Gibberellins biosynthesis courses, reduced vegetative growth more intensively than root growth by this compound.

REFLECTION OF THE ANTHROPIC IMPACT ON SPECIES AND POPULATION OF THE BARRA DE CATUAMA BEACH (GOIANA-PE)

Research article of Journal of Plant and Environmental Research REFLECTION OF THE ANTHROPIC IMPACT ON SPECIES AND POPULATION OF THE BARRA DE CATUAMA BEACH (GOIANA-PE) Marcos Vinícius da Silva Alves de Lima¹* Matheus Alves Siqueira de Assunção¹ Ingrid Andrêssa de Moura¹ Maria Eduarda dos Santos Pereira de Oliveira¹ Anna Thereza de Oliveira Barbosa¹ Anna Claudia Santos Mendonça¹, Fálba Bernadete Ramos Anjos2. ¹Graduandos do curso de Ciências Biológicas – Bacharelado, Centro de Ciências Biológicas, Universidade Federal de Pernambuco; 2 Professor Doctor of the Federal University of Pernambuco (UFPE) Objective: The objective of this article is to make an analysis of the anthropic impact on the lo-cal species of Barra de Catuama beach, which is located in the Southeast of the municipality of Goiana, Pernambuco. Methods: For this purpose, we used the methodology of analysis of pho-tos, reading articles published about the subject, and the tools found on the internet, such as news and videos. Results: Through analysis of photos and bibliography, it was possible the perception of the anthropic impact relactive to social, environmental and economic’s quality, in Barra de Catuama beach, since the presence of solid waste and domestic sewage accounted in the decrease of species of the region and of tourists. Conclusion: The conclusion of this ana-lyzes is that the ecological and public damage, prevent the recreation of the bathers and have a direct influence on the fishing and catching crabs, those are one of the main sources of income in the region, stressing that this anthropic impact resulted in the decrease of the population of the species, and a deviation of the local income.

Study on ecological restoration and landscape design strategies of abandoned mines

Research article of Journal of Plant and Environmental Research Study on ecological restoration and landscape design strategies of abandoned mines Wei Li College of Biology and Food Engineering,Huanghuai University, Henan 463000, China In recent years, with peoples environmental protection continuous enhance and the proposal of the national sustainable development strategy, the restoration and landscape reconstruction of abandoned mines have begun to receive the attention of the government, experts and scholars in various fields[1].People realized that they can restore the abandoned land ecology through the knowledge of natural science and engineering disciplines. Landscape reconstruction and development can improve the living environment of residents which is also an important way to create economic value and realize the harmonious coexistence of human and nature. In this article, it is focus on the discussion which include how to carry on the ecological restoration of mining abandoned land, and the problem of landscape design modification, it is also put forward the concept of ecological recovery[2], discuss on the relationship between ecological restoration and design modification, and how to implement both of them at the same time, The article introduces the methods of how to implement in details, to provide the reference for the future on rehabilitation and reconstruction of mine waste land in practice . Keywords: Mine abandoned Land, Ecological Restoration, Landscape Design, Comprehensive Management and Environmental Protection ...
