Large Variation Found in the Phytochemical and Antioxidant Activity of Peach and Plum Germplasm Tập 132 Số 3 - Trang 334-340 - 2007
M. Vizzotto, Luis Cisneros‐Zevallos, David Byrne, David W. Ramming, W.R. Okie
Nineteen peach [Prunus persica (L.) Batsch] genotypes and 45 plum (Prunus
salicina Erhr. and hybrids) genotypes with different flesh and skin color were
analyzed for their antioxidant content and activity. Anthocyanin content,
phenolic content, and antioxidant activity were higher in red-flesh than in
light-colored flesh peaches. Carotenoid content was higher in yellow-flesh
peaches than in light-... hiện toàn bộ
Tissue Culture-induced Variation in Scented Pelargonium spp.1 Tập 101 Số 3 - Trang 281-290 - 1976
R. M. Skirvin, Jules Janick
Abstract In vitro techniques were developed to regenerate plantlets
(calliclones) from callus of scented geraniums (Pelargonium spp.). Calliclones
were compared to plants derived from stem, root, and petiole cuttings of 5
cultivars. Plants from stem cuttings of all cultivars were uniform and identical
to the parental clone. Plants from root and petiole cuttings were more variable
with the amount o... hiện toàn bộ
Flowering and Fruit Set of Olive Trees in Response to Nitrogen, Phosphorus, and Potassium Tập 133 Số 5 - Trang 639-647 - 2008
Ran Erel, Arnon Dag, Alon Ben‐Gal, Amnon Schwartz, Uri Yermiyahu
The independent effects of nitrogen, phosphorus, and potassium concentrations in
the irrigation solution on flowering and fruit set in olive trees (Olea europaea
L. cv. Barnea) were studied in a container experiment. Treatments included eight
levels of N ranging from 0.4 to 14.1 mm, seven levels of P ranging from 0.01 to
0.62 mm, and seven levels of K ranging from 0.25 to 5.33 mm. At low
environme... hiện toàn bộ
Color and Phenolic Content Changes during Flower Development in Groundcover Rose Tập 135 Số 3 - Trang 195-202 - 2010
Valentina Schmitzer, Robert Veberič, Gregor Osterc, Franci Štampar
In the present study, the chemical and morphological status of eight cultivars
of groundcover rose (Rosa ×hybrida) with a range of flower colors was
investigated. From the methanolic extracts of rose petals collected from flowers
at four developmental stages, several phenolic compounds were identified via
high-performance liquid chromatography/mass spectrometry, including five
anthocyanins, which ... hiện toàn bộ
End-product Inhibition of Photosynthesis in Prunus cerasus L. in Response to Whole-plant Source-Sink Manipulation Tập 120 Số 4 - Trang 583-599 - 1995
Desmond R. Layne, James A. Flore
The source-sink ratio of l-year-old, potted `Montmorency' sour cherry (Prunus
cerasus) trees was manipulated by partial defoliation (D) or continuous lighting
(CL) to investigate the phenomenon of end-product inhibition of photosynthesis.
Within 24 hours of D, net CO2 assimilation rate (A) of the most recently
expanded source leaves of D plants was significantly higher than nondefoliated
(control)... hiện toàn bộ
Growth and Gas Exchange by Lettuce Stands in a Closed, Controlled Environment Tập 119 Số 3 - Trang 610-615 - 1994
Raymond M. Wheeler, Cheryl L. Mackowiak, John C. Sager, N.C. Yorio, W. M. Knott, Wade L. Berry
Two studies were conducted in which `Waldmann's Green' lettuce (Lactuca sativa
L.) was grown hydroponically from seed to harvest in a large (20-m2),
atmospherically closed growth chamber for the National Aeronautics and Space
Administration's controlled ecological life support system (CELSS) program. The
first study used metal-halide (MH) lamps [280 μmol·m-2·s-1 photosynthetic photon
flux (PPF)], ... hiện toàn bộ
Seismomorphogenic Regulation of Plant Growth1 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
