Inhibition of photosynthesis was followed during autumn and early winter in current-year sun
and shade needles of unfertilized and fertilized Norway spruce [Picea abies (L.) Karst.] by …

Using the expression of fluorescence originated from the PSII open reaction center in the
light by Oxborough and Baker (1997), we obtained a formula that expresses relationships …

The extent of photoinhibition of PSII is determined by a balance between the rate of
photodamage to PSII and that of repair of the damaged PSII. It has already been indicated …

Recent reports have indicated a considerably inactivated PSII in twig cortices, in spite of the
low light transmittance of overlying periderms. Corresponding information for more deeply …

To reveal the roles of stems in responding to the surrounding light environment, the optical
properties of stem tissues of five woody species and their effect on bark, xylem and pith …

To reveal the dynamics of short-term photosynthetic acclimation to increased irradiance, the
light response of photochemical (qp), non-photochemical (qN) and F0 (q0) quenchings of …

Green leaves illuminated with photosynthetically active light emit red fluorescence, whose
time-dependent intensity variations reflect photosynthetic electron transport (the Kautsky …

The photosynthetic performance of developing spruce (Picea abies L. Karst.) needles was
investigated. As revealed by previous reports, the biosynthesis of chlorophylls and …

The photosynthetic apparatus rapidly responds to the environmental influences. In vivo
chlorophyll fluorescence was applied for the evaluation of photosystem II (PSII) and electron …

Functioning of photosystem II (PSII) is the most sensitive indicator of environmental stress in
plants. Changes in PSII activity can be assayed rapidly and non-destructively by …
