Plantlets of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) had lower rates of net CO(2) uptake and higher rates of root respiration than greenhouse-grown seedlings. They also had a lower photosynthetic efficiency at high photosynthetic photon fl

An aseptic gas exchange and hydroponic system (AGEHS) has been developed in an attempt for characterization of physiological requirements for photoautotrophic growth in vitro and alleviation of the needs for ex vitro acclimatization. The AGEHS monito

Tissue-culture plantlets of Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] were highly susceptible to detrimental water loss upon removal from culture in vitro. Control of net water loss was related to shoot and root morphology. Relative water co

The process by which Bursaphelenchus xylophilus causes death of Scots pine ( Pinus sylvestris ) seedlings was studied by monitoring daily changes in soil and needle water potential and variable chlorophyll a fluorescence (a measure of the status of t

Plantlets of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), taken at transplantation and at 7 weeks after transplantation to greenhouse conditions, were compared morphologically to 7–9 week-old greenhouse-grown seedlings. Compared to seedlings

Conifers in the temperate zone are subject to extremes in climatic conditions, such as low temperatures and water deficits. Under such conditions chloroplast antenna pigments can absorb more light energy than can be utilized in photosynthesis. If the

The objective of this investigation was to test for the possible effects of plantlet morphology and environmental stress on survival and growth during the acclimatization of tissue-cultured Douglas fir [Pseudotsuga menziesii (Mirb.) Franco]. Under a

Dry lettuce seeds (Lactuca sativa L. cv. Grand Rapids), which received 5 min far-red light (FR) 0-5 h after the onset of water imbibition, showed 17% and 50% germination without and with acid immersion treatment (pH 01) for 1 h and rinsing with water

A chlorophyll fluorescence induction (Kautsky effect) assay predicted ozone-induced injury in bean leaves (Phaseolus vulgaris) at least 20 hours before any visible sign of leaf necrosis. The extent of injury, which could be predicted during exposure
