Response of Paspalum Vaginatum Turfgrass Grown Under Shade Conditions to Paclobutrazol and Trinexapac-Ethyl As Plant Growth Retardants (Pgrs)
Journal of Horticultural Science & Ornamental Plants 4 (2): 134-147, 2012 ISSN 2079-2158 © IDOSI Publications, 2012 Response of Paspalum vaginatum Turfgrass Grown under Shade Conditions to Paclobutrazol and Trinexapac-Ethyl as Plant Growth Retardants (PGRs) M.M.M. Hussein, H.A. Mansour and H.A. Ashour Department of Ornamental Horticulture, Faculty of Agriculture, Cairo University, Giza, Egypt Abstract: This study was conducted at the Experimental Nursery of the Ornamental Horticulture Department, Faculty of Agriculture, Cairo University during the two successive seasons of 2009/2010 and 2010/2011. This work aimed to investigate the response of paspalum (Paspalum vaginatum, Swartz cv. Salam) grown under different shade levels to foliar application of different concentrations of paclobutrazol and trinexapac-ethyl (TE). The turfgrass was covered with shade cloth of different light permeability levels providing shading levels of 42%, 63% and 70% of natural light. In addition, full sunlight (unshade) was used as a control. Plants grown under different shade levels treatments were sprayed monthly with either paclobutrazol (at 750 or 1500 ppm) or TE (at 200 or 400 ppm). Control plants were sprayed with tap water.It can be concluded that Paspalum vaginatum plants can be grown under shade level up to 42% with no significant reduction in growth. However, if shade level exceeds 42% (up to 70%) paclobutrazol at 1500 ppm or TE at 400 ppm can be used monthly as a foliar application to overcome the adverse effects of shade. Key words: Paspalum vaginatum Shade level Trinexapac-ethyl (TE) Paclobutrazol INTRODUCTION biosynthesis pathway [7]. Pessarakli [8] stated that TE application increases leaf tissue levels of the cytokinin Seashore paspalum (Paspalum vaginatum, Swartz) is zeatin riboside. -
Construction of High-Resolution Genetic Maps Of
Huang et al. BMC Genomics (2016) 17:562 DOI 10.1186/s12864-016-2969-7 RESEARCH ARTICLE Open Access Construction of high-resolution genetic maps of Zoysia matrella (L.) Merrill and applications to comparative genomic analysis and QTL mapping of resistance to fall armyworm Xiaoen Huang1†, Fangfang Wang1†, Ratnesh Singh1†, James A. Reinert1, M. C. Engelke1, Anthony D. Genovesi1, Ambika Chandra1,2 and Qingyi Yu1,3* Abstract Background: Zoysia matrella, widely used in lawns and sports fields, is of great economic and ecological value. Z. matrella is an allotetraploid species (2n =4x = 40) in the genus zoysia under the subfamily Chloridoideae. Despite its ecological impacts and economic importance, the subfamily Chloridoideae has received little attention in genomics studies. As a result, limited genetic and genomic information are available for this subfamily, which have impeded progress in understanding evolutionary history of grasses in this important lineage. The lack of a high-resolution genetic map has hampered efforts to improve zoysiagrass using molecular genetic tools. Results: We used restriction site-associated DNA sequencing (RADSeq) approach and a segregating population developed from the cross between Z. matrella cultivars ‘Diamond’ and ‘Cavalier’ to construct high-resolution genetic maps of Z. matrella. The genetic map of Diamond consists of 2,375 Single Nucleotide Polymorphism (SNP) markers mapped on 20 linkage groups (LGs) with a total length of 1754.48 cM and an average distance between adjacent markers at 0.74 cM. The genetic map of Cavalier contains 3,563 SNP markers on 20 LGs, covering 1824. 92 cM, with an average distance between adjacent markers at 0.51 cM. -

Grass Genera in Townsville
Grass Genera in Townsville Nanette B. Hooker Photographs by Chris Gardiner SCHOOL OF MARINE and TROPICAL BIOLOGY JAMES COOK UNIVERSITY TOWNSVILLE QUEENSLAND James Cook University 2012 GRASSES OF THE TOWNSVILLE AREA Welcome to the grasses of the Townsville area. The genera covered in this treatment are those found in the lowland areas around Townsville as far north as Bluewater, south to Alligator Creek and west to the base of Hervey’s Range. Most of these genera will also be found in neighbouring areas although some genera not included may occur in specific habitats. The aim of this book is to provide a description of the grass genera as well as a list of species. The grasses belong to a very widespread and large family called the Poaceae. The original family name Gramineae is used in some publications, in Australia the preferred family name is Poaceae. It is one of the largest flowering plant families of the world, comprising more than 700 genera, and more than 10,000 species. In Australia there are over 1300 species including non-native grasses. In the Townsville area there are more than 220 grass species. The grasses have highly modified flowers arranged in a variety of ways. Because they are highly modified and specialized, there are also many new terms used to describe the various features. Hence there is a lot of terminology that chiefly applies to grasses, but some terms are used also in the sedge family. The basic unit of the grass inflorescence (The flowering part) is the spikelet. The spikelet consists of 1-2 basal glumes (bracts at the base) that subtend 1-many florets or flowers. -

Melatonin Influences the Early Growth Stage in Zoysia Japonica Steud. By
www.nature.com/scientificreports OPEN Melatonin infuences the early growth stage in Zoysia japonica Steud. by regulating plant oxidation and genes of hormones Di Dong, Mengdi Wang, Yinreuizhi Li, Zhuocheng Liu, Shuwen Li, Yuehui Chao* & Liebao Han* Zoysia japonica is a commonly used turfgrass species around the world. Seed germination is a crucial stage in the plant life cycle and is particularly important for turf establishment and management. Experiments have confrmed that melatonin can be a potential regulator signal in seeds. To determine the efect of exogenous melatonin administration and explore the its potential in regulating seed growth, we studied the concentrations of several hormones and performed a transcriptome analysis of zoysia seeds after the application of melatonin. The total antioxidant capacity determination results showed that melatonin treatment could signifcantly improve the antioxidant capacity of zoysia seeds. The transcriptome analysis indicated that several of the regulatory pathways were involved in antioxidant activity and hormone activity. The hormones concentrations determination results showed that melatonin treatment contributed to decreased levels of cytokinin, abscisic acid and gibberellin in seeds, but had no signifcant efect on the secretion of auxin in early stages. Melatonin is able to afect the expression of IAA (indoleacetic acid) response genes. In addition, melatonin infuences the other hormones by its synergy with other hormones. Transcriptome research in zoysia is helpful for understanding the regulation of melatonin and mechanisms underlying melatonin- mediated developmental processes in zoysia seeds. Melatonin (MT, N-acetyl-5-methoxytryptamine), commonly known as a vertebrate neurohormone released by the pineal gland, is a tryptophan-derived metabolite. Melatonin is a versatile substance with diverse efects in various animal physiological processes. -

An Ecological Model to Classify and Monitor Mountain Plover Nesting Habitat on Grasslands in Colorado
AN ECOLOGICAL MODEL TO CLASSIFY AND MONITOR MOUNTAIN PLOVER NESTING HABITAT ON GRASSLANDS IN COLORADO Daniel W. Uresk, USDA Forest Service, Rapid City SD 57701 ABSTRACT A multivariate statistical model based on vegetation and soil surface characteristics was developed to classify and monitor mountain plover (Charadrius montanus) habitat groupings and nest selection. Data were collected on the shortgrass prairie, Pawnee National Grassland, Colorado. Vegetation and soil surface characteristics were sampled from late April to early June of 1999 and 2000 during the nesting season. Samples were collected on random sites in 43 sections and at 54 nest sites within adjacent townships. Random data were clustered into three habitat groups consisting of high, mid and low nesting habitat. Key variables in the model for classifying and monitoring nest habitat were percent bare ground, percent canopy cover for blue grama (Bouteloua gracilis) and buffalograss (Bouteloua dactyloides). The three nest habitat groupings were quantitatively identified with an estimated 97 percent accuracy. The model classified the 54 mountain plover nest sites as either high, mid or low nesting habitat. High mountain plover nest preference (39 nests) for bare ground was 46 percent, with blue grammar 27 percent and buffalograss at 2 percent (n = 39 nest sites). Mid classified nests (12) selected 23 percent bare ground, 60 percent blue grama and 1 percent buffalograss. Three nests were classified as low nesting habitat, which exhibited 25 percent bare ground, 41 percent buffalograss and 17 percent blue grama. Mountain plovers selected nest sites that had short plant structure, a mean visual obstruction reading (VOR) of 0.25 cm at nesting and ranged from 0 to 1.6 cm. -
