Rapid Determination of Volatile Constituents from the Buds and Flowers of Prunus Persica (L.) Batsch. f. duplex Rehd
The head-space (HS) volatile compounds of the buds and flowers of Prunus persica (L.) Batsch. f. duplex Rehd were analysed by solid-phase microextraction (SPME) coupled with capillary gas chromatography/mass spectrometry (GC-MS). Typical compounds detected in P. persica (L.) Batsch. f. duplex Rehd buds and flowers were alkanes. Tetradecane (4.07%), 4,8- dimethyl undecane (4.56%), pentadecane (11.3%) and hexadecane (4.62%) were identified as the main compounds in the buds, and tricosane (20.03%) , hexadecane (3.34%) were detected in the flowers as the main alkanes. On the other hand, (Z)-octadec-9-enoic acid (20.94%) was found in the buds as the main compounds.
Sea Buckthorn: New Crop Opportunity
Sea buckthorn (Hippophae rhamnoides L., Elaeagnaceae) is a winter hardy, deciduous shrub with yellow or orange berries (Bailey and Bailey 1978). It develops an extensive root system rapidly and is therefore an ideal plant for preventing soil erosion and land reclamation. It can withstand temperatures from –43° to 40°C (Lu 1992). It is considered to be drought resistant (Heinze and Fiedler 1981); however, irrigation is needed in regions receiving <400 mm of rainfall per year for better growth (Li and Schroeder 1996).
WOODY ORNAMENTAL PLANT ZONATION: III. SUITABILITY MAP FOR THE PROBABLE WINTER SURVIVAL OF ORNAMENTAL TREES AND SHRUBS
A map showing suitability for winter survival of ornamental trees and shrubs has been prepared for Canada. It is based on the estimated suitability indices (from 0 to 92) for 640 localities. It includes 10 zones with a spread of 10 units; each zone is subdivided into 2 sub-zones. In addition, probability curves indicate the chances of survival within zones and sub-zones of any plant for which the index of hardiness is known.
