Local pollen rain is derived from plants that grow at or very close to the sampling point. High local values are common in all sorts of vegetation types: lakes, bogs, marshes, and forests. Extralocal pollen rain is derived largely... CR Janssen - 《Ecology》 被引量: 343发表: 1966年 Ho...
Winter vegetation and summer dormancy of plants in the arid zone of TajikistanData are given on the carbohydrate contents of storage organs of Hordeum bulbosum during the year; carbohydrates were accumulated during growth and broken down during the period of summer dormancy and subsequently used in ...
Normally, although the stomata reopen slowly and the rate of photosynthesis increases when flood water drains away, previously-flooded plants may have difficultly recovering to normal levels of growth, photosynthetic capacity, and other physiological responses, because absorption of water by their small r...
With climate change leading to increasingly more unpredictable weather, it’s more important than ever to know your plant hardiness zone and which plants could be felled by a cold snap. “Look up the plant—sometimes each variety or even cultivar has slightly different temperature tolerance,” cau...
Introduction In the nival life zone, the snow-free time slot is short, not exceeding 2–3 months [1,2]. During this time, freezing temperatures are frequent. Despite global warming, frost is anticipated to remain a predominant factor, as alpine plants seem to be exposed to...
The plants in the row were then cut at ground level for DM and N content analyses in the laboratory. The Dualex measurements were systematically performed on the middle of the main shoot, i.e., the youngest upper fully developed leaf of the canopy, with the adaxial leaf side facing the ...
16kAccesses 37Altmetric Metrics Abstract The late Miocene offers the opportunity to assess the sensitivity of the Earth’s climate to orbital forcing and to changing boundary conditions, such as ice volume and greenhouse gas concentrations, on a warmer-than-modern Earth. Here we investigate the rela...
A method of Winter Rape Cold Resistance Identification and Evaluation, the former field soil frozen, take the upper part of the different winter rapeseed plants fully extended and vigorous growth of the leaf, and take the appropriate root of the plant, number and placed in an ice box; ...
Furthermore, in VER2-OE lines, the nuclear accumu- lation of TaGRP2 started to decrease earlier, after 7 days of cold exposure, whereas it was delayed to 21 days in VER2-Ri plants (Fig. 6b). The total amount of TaGRP2 protein did not show any significant change in either VER2-...
Therefore, in this complex agricultural structure, the winter wheat plants span a large north-south area and show high variability, which makes extraction difficult. The phenological periods of the two crops in the study area are presented in Table 1 and shown in Figure 2. The colors represent...
