Comparative Study of Leaf Surface Texture and Ability to Expand of Cured Tobacco [PDF]

open access: yesContributions to Tobacco & Nicotine Research, 2001
Abstract Tobacco leaf texture, appreciated by the difference of surface roughness of cured leaves, is studies with light microscopy and scanning electron microscopy (SEM). The leaf texture is obviously determined by the presence or absence of conical cellular protuberances on the adaxial side of the leaf.

Leaf Initiation: New Developments in an Expanding Field [PDF]

open access: yesThe Plant Cell, 1998
The regular geometries of plants have inspired generations of botanists, philosophers, and mathematicians. Perhaps the most basic of plant patterns, the arrangement of leaves along a stem, the phyllotaxy, inspired the statement “from the contemplation of Plants, men might first be invited ...

Microspectrofluorometric Measurement of Chloroplast DNA in Dividing and Expanding Leaf Cells of Spinacia oleracea [PDF]

open access: yesPlant Physiology, 1986
Absolute DNA amounts of individual chloroplasts from mesophyll and epidermal cells of developing spinach leaves were measured by microspectrofluorometry using the DNA-specific stain, 4,6-diamidino-2-phenyl indole, and the bacterium, Pediococcus damnosus, as an internal standard.

Chemical Defoliation of Pin Oak in the Expanding Leaf Stage1

open access: yesHortScience, 1978
Abstract Low levels of 7-oxabicyclo(2,2,1)heptane-2,3-dicarboxylic acid (endothall), ranging from 37.5 to 300 ppm, combined with 1000 ppm of (2-chloroethyl)phosphonic acid (ethephon) and sprayed on pin oak ( Quercus palustris Muenchh.) seedling sprouts in the greenhouse ...

Leaf Primordium Initiation and Expanded Leaf Production are Co-ordinated through Similar Response to Air Temperature in Pea (Pisum sativumL.) [PDF]

open access: yesAnnals of Botany, 1997
Accurate prediction of the timing of leaf area development is essential to analyse and predict the responses of crops to the environment. In this paper, we analyse the two processes determining the chronology of leaf development—initiation of leaf primordia by the shoot meristem and production of expanded leaves out of the shoot tip—in several pea ...

COP Improvement Of A CO2 Refrigeration System With An Expander-Compressor-Unit (ECU) In Subcritical And Transcritical Operation [PDF]

open access: yes, 2012
One of the most attractive low GWP and zero ODP refrigerants is carbon dioxide (R744). The use of CO2 in low temperature stages of cascade systems is nowadays state of the art.

Sustainable design and durability of domestic micro combined heat and power scroll expander systems. [PDF]

open access: yes
Research to understand the mechanisms of wear within the main components of three different micro-CHP scroll expander systems was conducted. This was performed in order to identify the possible tribo-mechanical effects (abrasion, adhesion, cavitation ...
