TL;DR: Potatoes (Solamum tuberosum L.) were planted in pots in a temperature-controlled glasshouse to collect data on the rate of leaf apearance, leaf expansion, apical lateral branching and active life spans of leaves.

TL;DR: The leaf extension rate (LER) of tall fescue was studied in the field under various nitrogen and temperature regimes and two distinct relationships between the LER and the temperature were obtained, one for vegetative growth and one for the reproductive period.

TL;DR: In this article, relative nuclear DNA contents in tomato seed and seedling tissues were measured with flow cytometry, and they provided information about the replication stage of nuclei in cells of non-imbibed, hydrated and primed seeds and specified the tissue in which DNA replication occurs.

TL;DR: Compartment models for nutrient dynamics have been developed to represent the distribution of nutrient pools and net annual fluxes within the system and indicate the greater productivity of the stands, which was due to the higher dry matter dynamics and nutrient release for the growing vegetation.

TL;DR: The accumulation rotes of dry motter and nitrogen showed on upper limit of response to nitrogen supply; N3 plants continued to accumulate dry- matter -and N at a constam rate for a longer period of time than N2 and N1 plants.

TL;DR: Quantitative relationships were established which defined the partitioning of nitrogen and dry matter between the leaves, stems and roots during the development of field grown lucerne, which was unaffected by whether or not N fertilizer was applied.

TL;DR: The structure of nodules from aquatic and vermiculite-grown plants were compared, particular attention being paid to the cell layers external to the infected region (the nodule cortex) because, in other species, these are believed to be the site of an oxygen diffusion resistance mechanism.

TL;DR: Durations from sowing to panicle emergence in 16 diverse genotypes of rice (Oryza sativa L.) were recorded in 13 different photothermal regimes, comprising constant and diurnally alternating temperatures between 16 and 32 o C and photoperiods between 10.5 and 15.0 h d -1.

TL;DR: Variation in the value of KE is the source of the differences in potential longevity of the three subspecies of rice, and the view that the maximum seed storage moisture content which provides the maximum longevity is that which is in equilibrium with about 10-11% r.h.

TL;DR: The aim of this study was to examine the potential for light acclimation in shade grown seedlings of Bischofia javanica Blume and found the low-light (LL) leaf displayed photoinhibition immediately after transfer to high- light (HL) (...)

TL;DR: In stressed pollen, the extent of retention of fluorescence may give a better indication of pollen function than initial fluorescence, as is being done routinely in FCR test.

TL;DR: The dynamics of growth and proportional dry matter distribution between the vegetative parts and fruits of cucumber were studied daily during a growing season, indicating the plants were adapting to radiation.

TL;DR: The effects of CO 2 and nutrient availability were examined on growth, morphological and biochemical characteristics of Phaseolus vulgaris.

TL;DR: Early histodifferentiation of the embryo of Avicennia marina (Forssk.) Vierh.

TL;DR: Tiller appearance in tall fescue occurs in an orderly, predictable manner with the potential for a high degree of synchronization among tillers on a given plant.

TL;DR: Potential pre- anthesis and post-anthesis contributions of stem internodes to grain yield in crops of winter barley, and the role of stemInternodes in grain yield determination are studied.

TL;DR: A dynamic model for growth and mortality of individual plants in a stand was developed, based on the process of canopy photosynthesis, and assuming an allometric relationship between plant height and weight, i.e. allocation-growth pattern of plant Height and stem diameter.

TL;DR: The origin and early development of angle meristems in Selaginella martensii were studied using a high-resolution mould and cast technique for scanning electron microscopy, in conjunction with light microscopy.

TL;DR: It is concluded that effects of drought in the field on tillering cannot be attributed only to low water potential, as well as expected based on the theory of the functional balance between root and shoot.

TL;DR: The testa-imposed seed dormancy of 34 native Australian species of Faboideae and Mimosoideae was examined immediately after the seeds matured and again after 35 years of dry storage in the laboratory.

TL;DR: Plants of the quantitative short-day crop soya bean [Glycine max (L.) Merrill] cv.

TL;DR: Proplastids of both tapetal cells and microsporocytes were present early in anther development and were present in both vegetative and generative cells, while plastids were absent from sperm cells.

TL;DR: Daily replicas of the surfaces of Pisum sativum leaves were used to reconstruct the cellular development of specific regions of the epidermis.

TL;DR: The effects of the mode of between-individual competition on the stationary size distribution in uneven-aged and continually reproducing tree populations were investigated theoretically, based on the diffusion and continuity equation models.

TL;DR: The results indicate that the potential growth of even-aged plantations may be greater than that realized in poor soils with common levels of atmospheric N deposition and normal fertilizer regimes and that fertilizer application must be accurately matched to growth stage if fertilizer is to be used efficiently.

TL;DR: Ultrastructural changes associated with carnation petal senescence were investigated using ethylene levels of individual petals as a physiological monitor of thesenescence process.

TL;DR: The durations of the photoperiod-sensitive and phot operiod-insensitive phases of development to panicle emergence were estimated in four contrasting indica cultivars of rice (Oryza sativa L.) in a reciprocal-transfer experiment.

TL;DR: The ultrastructure of the secretory cells suggests the involvement of ER, Golgi and plastids in nectar secretion in Limodorum abortivum.

TL;DR: Nitrate reductase activity (NRA, in vivo assay) and nitrate (NO 3 - ) content of root and shoot and NO 3 - and reduced nitrogen content of xylem sap were measured in temperate cereals and temperate pasture grasses.
