The effect of nightly temperature drops of different durations (2, 4, and 6 h) on the processes of apical and axillary meristem organogenesis was studied in young Cucumis sativus L. under short photoperiod (day/night, 10/14 h), long photoperiod (16/8 h), and continuous light. Nightly temperature drops for 2 h had no effect on cucumber development under all(More)
The development cycle of the elementary unit of a shoot system (EUS) and of perennial axes consisting of these shoots in adult plants of Andromeda polifolia L. was investigated in the Kola Peninsula. It was established that EUS is a monocarpic shoot consisting of 14–26 metameres with three-year life cycle. The cycle consists of four phases: the initial(More)
The color preferences of the green-veined white butterfly Pieris napi (Linnaeus, 1758) that are associated with its foraging behavior were studied in experiments with artificial flower models. It was found that newly emerged inexperienced butterflies that are searching for food prefer flower models that are blue or red and select yellow ones at a(More)
We studied the influence of daily temperature gradients on organogenesis in apical and axil shoot meristems at different developmental stages in Cucumis sativus L. The level of organogenic activity of meristems was determined according to the number of leaf primordia on the main and lateral shoots, number of 2nd order shoots, and rudiments of flowers of(More)
