BHATTACHARYA Department of Zoology, Unive1'sity of Kalyani, Kalyani-741236 ABSTRAor The present paper provides an account of gall aphids and aphid galls of the subfamily Pemphiginae in the Indian region. l\Ioreovel', host association, gall record and biological knowledge of such species in the regio~ have also been included. A new gall forming species, Kaltenbachiella carp1nicola infesting Oarpinus BP, is described in this paper. A total of 27 species including 8 newly recorded one under this subfamily are known to produce galls in the area. INTRODUCTION tribes known from Indian region, about 27 Aphid galls are anatomically and histologi­ species are known to form galls. Many of cally complext formed mostly on the primary .these Pemphigid galls from Indian region host-plants, in the course of heteroecious have been described by Buckton (1896, 1897), life cycle and associa tion with true galls is Keiffer (1908), Das (1918)t Gulamullah (1941), regar.ded to be of primitive origin.

  • Poplars and Willows: Trees for Society and the Environment / Edited by J.G
    Poplars and Willows Trees for Society and the Environment This volume is respectfully dedicated to the memory of Victor Steenackers. Vic, as he was known to his friends, was born in Weelde, Belgium, in 1928. His life was devoted to his family – his wife, Joanna, his 9 children and his 23 grandchildren. His career was devoted to the study and improve- ment of poplars, particularly through poplar breeding. As Director of the Poplar Research Institute at Geraardsbergen, Belgium, he pursued a lifelong scientific interest in poplars and encouraged others to share his passion. As a member of the Executive Committee of the International Poplar Commission for many years, and as its Chair from 1988 to 2000, he was a much-loved mentor and powerful advocate, spreading scientific knowledge of poplars and willows worldwide throughout the many member countries of the IPC. This book is in many ways part of the legacy of Vic Steenackers, many of its contributing authors having learned from his guidance and dedication. Vic Steenackers passed away at Aalst, Belgium, in August 2010, but his work is carried on by others, including mem- bers of his family.

The pest continues to increase its range in these countries (Orlinski et al., 1991; EPPO, 2005). T. sartus was also found in several poplar trees in South Kazakhstan (Shymkent), however, the researcher believes that the pest will not be able to survive there (Kostin, 1973). There is some information about findings in Japan, Malaysia and Sri Lanka (CAPS Program Resource, 2020) but more data is needed to confirm these findings.

This is an important technique to synthesize metal oxide nanoparticles. In the current study, iron oxide nanoparticles (Fe2O3-NPs) were formulated by using Populus ciliata leaf extract and ferrous sulphate (FeSO4.7H2O). These NPs were analyzed by X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Fourier Transform Spectroscopy (FT-IR), and Energy Dispersive X-ray (EDX). The synthesized NPs were used against Gram positive and negative bacteria to find their bactericidal potential. These NPs were found active against Klebsiella pneumonia, Escherichia coli, Bacillus (B) lichenifermis and B. subtilis. B. licheniformis showed the highest antibacterial activity (zone of inhibition) up to 29.1±0.5 mm at 8 mg/mL concentration. This study concludes that Populus ciliata conjugated Iron oxides NPs could be used a potential antibacterial agent.

  • Populus Tree Improvement in Northern India
    POPULUS TREE IMPROVEMENT IN NORTHERN INDIA S. B. Land, Jr.1 and N. B. Singh2 Abstract:--The status of tree improvement for Populus species in the hills and alluvial plains of northern India (above 28° N latitude) was assessed during two visits by the senior author in 1996. Populus deltoides Bartr. ex Marsh. var. deltoides from the USA is economically the most important Poplar species, but additional superior-performing clones need to be developed. Selection and studies of genetic variation in the indigenous poplars have started slowly and need to be accelerated, but hybridization work with Populus ciliata Wall. ex Royle appears promising for the hills. An All-India Coordinated Project on Poplar Improvement (AICPPI) has now been organized by the Indian Council of Forestry, Research & Education to coordinate and direct poplar improvement in the country, and Dr. N. B. Singh has been appointed director of the project. Priorities will be breeding Populus deltoides for agroforestry in the alluvial plains of northern India, developing indigenous poplars and hybrids for the hilly region of northern India, and introducing and testing subtropical and tropical poplars for agroforestry in central India. Keywords: Populus deltoides Bartr. ex Marsh. var. deltoides, Populus ciliata Wall. ex Royle, India. INTRODUCTION The objective of this paper is to report the current status of Populus tree improvement research, development, and use in northern India. Information was obtained by the senior author from interviews, field trips, and reference materials during two visits to India in 1996. The visits were part of a consultancy activity between Winrock International Institute for Agricultural Development and the Indian Council of Forestry, Research and Education (ICFRE).

  • Populus Ciliata Wallich Ex Royle Salicaceae Parari Pipal, Paluch, Palachh, Himalayan Poplar
    Populus ciliata Wallich ex Royle Salicaceae parari pipal, paluch, palachh, Himalayan poplar LOCAL NAMES Bengali (bangikat); English (Himalayan poplar); Hindi (chalun,ban pipal,bagnu,chalni,safeda,pahari pipal,chalaun); Nepali (Bhote pipal,bangikat,bange kath); Trade name (Himalayan poplar,palachh,paluch,parari pipal) BOTANIC DESCRIPTION A mature Populus ciliata is a large deciduous tree with tall clean straight bole and broad rounded crown. The bark of young trees is smooth greenish-grey and that of the old trees dark brown with deep vertical fissures. Leaves resemble those of pipal (Ficus religiosa) to earn it the name Pahari pipal; broadly ovate or ovate-lanceolate, with serrulate-crenate and ciliate margins, 7.5-18.0 cm long, base usually cordate, 3-5 nerved; petiole 5-12.5 cm long, compressed above. Flowers in drooping raceme-like catkins appearing before or with leaves. Perianth of male flowers bell-shaped and female flowers bluntly toothed. Capsule 3 or 4-valved and encloses an average of 100-150 seeds. BIOLOGY Flowers appear when the trees are still leafless. The wind-pollinated tree has separate male and female flowers borne on separate trees. The ratio of male to female trees varies with site, and on the whole, male trees number more than females in natural populations. The fruits ripen in about 3 months after pollination. Seed dispersal takes place from about the middle of June to the middle of July depending upon the climate of the locality. Early monsoon showers during the seed dispersal period cause the capsules to close. They re-open again to disperse seed in dry spell in July-August.

    Life Science Journal, Volume 8, Issue 1, 2011 http://www.lifesciencesite.com Effect of Different Media and Growth Regulators on the in vitro Shoot Proliferation of Aspen, Hybrid Aspen and White Poplar Male Tree and Molecular Analysis of Variants in Micropropagated Plants Salah Khattab Suez Canal University, Faculty of Agriculture, Department of Horticulture, Ismailia- Egypt [email protected] Abstract: Among other in vitro factors like temperature and light, concentration of plant growth regulators and medium constituents are two of the most important aspects of successful micropropagation. With the aim of optimization of in vitro multiplication of Populus alba L., Populus tremula L. and Populus tremula L. x Populus. tremuloides Michx , the effect of MS and WPM media with various concentrations of BAP and 2iP was studied. The following multiplication parameters were monitored: number of shoots regenerated/explant, explant height, and explants weight were determined. MS medium proved to be the most effective one, resulting in better and morphologically superior microshoots as compared to WPM medium in the case of Populus alba. However in Populus tremula and Populus tremula x Populus Tremuloides the highest number of shoots was found when grown on WPM medium. In all three poplar lines, the highest shoot multiplication was obtained on MS and WPM media supplemented with BAP at (0.1 and 0.2 mgl-1). Very poor multiplication was achieved on media with 2iP. Shoot tips were isolated and induced to root on MS medium supplemented with IAA, IBA and/or NAA (0.0, 0.1, 0.2 and 0.4 mg l -1). About 90% of the rooted plantlets tested have successfully established in soil.
