Genetic Variation in Date Palms Propagated from Offshoots and Tissue Culture
Journal of the American Society for Horticultural Science - Tập 130 Số 1 - Trang 46-53 - 2005
Vyacheslav Gurevich, U. Lavi, Yuval Cohen
Date palm (Phoenix dactylifera L.) is a major tree crop in arid regions of the Middle East and North Africa, having an important impact on the economy of many countries in these regions. Date palms are traditionally propagated through offshoots. The development of propagation methods through tissue culture resulted in massive expansion of date palm plantations. While most trees generated from tiss... hiện toàn bộ
Mechanical Conditioning for Controlling Excessive Elongation in Tomato Transplants: Sensitivity to Dose, Frequency, and Timing of Brushing
Journal of the American Society for Horticultural Science - Tập 121 Số 5 - Trang 894-900 - 1996
Lauren C. Garner, Thomas Björkman
During production of plug transplants, the high plant density results in rapid stem elongation as plants compete for light. The resulting tall, weak-stemmed plants are difficult to transplant and are easily damaged. One technique that can prevent excessive elongation is mechanical stimulation by brushing. Wide adoption of brushing is limited by a lack of information on how plants respond to variat... hiện toàn bộ
Seismomorphogenic Regulation of Plant Growth1
Journal of the American Society for Horticultural Science - Tập 100 Số 2 - Trang 161-165 - 1975
Cary A. Mitchell, Candace J. Severson, John A. Wott, P. Allen Hammer
Abstract Growth of Lycopersicon esculentum Mill, and Pisum sativum L. was dwarfed by various forms of mechanical stimulation including shaking, flexing, and rubbing of the plant axis. The general effect of gently shaking a tomato plant once or twice daily was a reduction in node and leaf number, shortening of internodes, nodal swelling, epinasty of leaves, deep greening of new leaves, and increase... hiện toàn bộ
Inhibition of Shoot Growth in Greenhouse-grown Tomato by Periodic Gyratory Shaking
Journal of the American Society for Horticultural Science - Tập 108 Số 5 - Trang 795-800 - 1983
John C. Heuchert, Cary A. Mitchell
Abstract Seedlings of tomato (Lycopersicon esculentum Mill. cv. Rutgers) were agitated periodically on a gyratory shaker. Shaking plants at 175 rpm for 5 minutes once daily during the winter reduced leaf area, stem length, and water content and dry weight of both leaves and stems. This treatment was ineffective when applied during the summer. Five- to 20-minute treatments applied 2 or 3 times dail... hiện toàn bộ
Characterization of Mechanical Stress Dwarfing in Chrysanthemum1
Journal of the American Society for Horticultural Science - Tập 102 Số 5 - Trang 591-594 - 1977
Caula A. Beyl, Cary A. Mitchell
Abstract Elongation growth of Chrysanthemum morifolium Ramat. cv. May Shoesmith was inhibited by daily shaking with an automated mechanical device. The dwarfing effect was more pronounced if plants were shaken at 0800 than at 1600 or 2400 hours. The longer the duration of stress, the greater the growth inhibition. Thirty seconds to 2 minutes of stress per day were required for significant dwarfing... hiện toàn bộ
Effects of Plant Tissue and DNA Purification Method on Randomly Amplified Polymorphic DNA-based Genetic Fingerprinting Analysis in Carrot
Journal of the American Society for Horticultural Science - Tập 124 Số 1 - Trang 32-38 - 1999
L. S. Boiteux, M. E. N. Fonseca, Philipp W. Simon
Seven plant genomic DNA purification protocols were evaluated for genetic fingerprinting analysis using six tissues obtained from inbred carrot (Daucus carota L.) lines. Evaluations included 1) DNA yield, 2) DNA purity, 3) DNA cleavage with HindIII, 4) DNA integrity, and 5) DNA suitability for amplification in a random amplified polymorphic DNA (RAPD) system. Significant differences were observed ... hiện toàn bộ
Significance of Pollutant Concentration Distribution in the Response of ‘Red Kidney’ Beans to Ozone1
Journal of the American Society for Horticultural Science - Tập 108 Số 2 - Trang 347-351 - 1983
Robert C. Musselman, R. J. Oshima, R. E. Gallavan
Abstract Bean plants (Phaseolus vulgaris L. cv. Red Kidney) exposed to ozone with a simulated ambient concentration distribution showed significantly more injury, less growth, and lower yield than those exposed to an equivalent dose of ozone with a uniform concentration distribution. The concentration distribution did not alter the type of biological response of ‘Red Kidney’ beans to ozone, an ind... hiện toàn bộ
Factors Affecting in Vitro Germination and Storage of Jojoba Pollen
Journal of the American Society for Horticultural Science - Tập 110 Số 5 - Trang 671-676 - 1985
Chin Won Lee, John C. Thomas, Stephen L. Buchmann
Abstract Conditions for in vitro germination of jojoba [Simmondsia chinensis (Link) Schneider] pollen were optimized in order to study the influence of storage temperature on viability. A medium consisting of 300 mg·liter−1 CaCl2·2H2O, 100 mg·liter−1 KNO3, 10 mg·liter−1 H3BO3, 20% sucrose, and 4% to 5% Difco Bacto-agar was optimal for germinating both fresh and stored pollen. Pollen germinated rea... hiện toàn bộ
Phytotoxic Effects of Gray Water Due to Surfactants
Journal of the American Society for Horticultural Science - Tập 122 Số 6 - Trang 792-796 - 1997
David L. Bubenheim, Kanapathipillai Wignarajah, W. E. Berry, T. Wydeven
Recycling wastewater containing soaps and detergents for plant growth is highly desirable when fresh water is limited. This is especially true during times of drought and is imperative in some specialized situations such as a regenerative space habitat. To regenerate food, water, and air, the National Aeronautics and Space Administration's Controlled Ecological Life Support System (CELSS) must rec... hiện toàn bộ
Stem-water Potential as a Sensitive Indicator of Water Stress in Prune Trees (Prunus domestica L. cv. French)
Journal of the American Society for Horticultural Science - Tập 117 Số 4 - Trang 607-611 - 1992
Harold McCutchan, Kenneth A. Shackel
The relative sensitivity of plant- and soil-based measures of water availability were compared for prune trees subjected to a range of irrigation regimes under field conditions. Over the growing season, leaf- and stem-water potentials (ψ) measured at midday exhibited clear differences between frequently irrigated trees and unirrigated trees that were growing on stored soil moisture. Stem ψ was les... hiện toàn bộ
