TL;DR: In this article, the effects of temperature on plant and crop processes are discussed and related to the underlying theory, by means of a critical and expository essay which aims to provide a conceptual basis for the consideration of these problems.

TL;DR: Final dry weight appeared to correlate well with the maximum number of endosperm cells, but depended also on the number of starch granules per cell, and the amount of dry matter per cell was not constant in both treatments.

TL;DR: It is suggested that over a wide range of conditions (covering the photothermal regimes experienced by lentil crops world-wide), time to flowering can be described by the equation 1/f = a + bt + cp where a, b and c are constants which differ between genotypes and the values of which provide a sound basis for screening germplasm for sensitivity to temperature and photoperiod.

TL;DR: It is proposed that the effect of both high temperature and low irradiance is brought about by the increased production of a growth substance, possibly gibberellin, which inhibits tuber formation, and that tuber yield is determined by the balance between temperature and irradiance.

TL;DR: The possible transitory, nutritive function of leaves produced in vitro is discussed and those leaves developing subsequent to transplanting are photosynthetically capable.

TL;DR: The percentage of essential oil and the number of peltate hairs were higher in the flowers than in the leaves, the highest being in the Flowers of a chemotype with a high phenol (thymol) concentration.

TL;DR: It is suggested that the photo-thermal response of flowering in chickpeas, over the range of environments normally experienced by the crop, may be described by the equation 1/f = a + bt + cp in which f is the number of days from sowing to first flower, t is mean temperature and p is photoperiod.

TL;DR: In the roots, the pattern of carbon allocation between respiration and carbon accumulation changed soon after imposition of drought, and total root respiration decreased under drought it became more energy efficient, particularly for Warigal, as less respiration took place via the alternative pathway.

TL;DR: Assimilate partitioning within the young truss was also affected by heat stress in both cultivars, but was more pronounced in Roma VF : at higher temperatures more 14C was found in the peduncle and in the older flower buds than in the younger flower buds.

TL;DR: It is suggested that growth retardation of cauliflowers, lettuce and celery, induced by mechanical stress such as brushing may prove valuable as a means of ‘conditioning’ the seedlings to withstand both the physical and physiological stresses which occur at and during transplanting.

TL;DR: The methods are suitable for production of plants for assessment of somaclonal variation in a range of genotypes and pronounced differences were observed in the response of different cultivars and explant sources to medium formulations containing different auxins or cytokinins.

TL;DR: It is concluded that relationships between some derived plant growth quantities may be non-unique, thus emphasizing the need for a critical understanding of the underlying physiological processes involved in plant growth.

TL;DR: The data indicate that the growth characteristics of soybean seed are influenced by the supply of assimilate to the seed during the linear phase of seed development.

TL;DR: A mathematical model of oxygen diffusion in a legume root nodule is constructed and validated and support is given to the concept of a part water-filled diffusion pathway.

TL;DR: It was concluded that the better N-use efficiency of C 02 enriched plants could result in increased growth of X. occidentale in regions of marginal soil fertility as atmospheric levels of C02 increase.

TL;DR: A method for characterizing the resistance to oxygen diffusion in legume nodules has been developed and when the carbohydrate status of the nodules was reduced by dark treatments, the minimum diffusion resistance increased, and after 24–28 h darkness equalled the maximum resistance.

TL;DR: Intra- and extracellular Cd uptake were investigated in the moss Rhytidiadelphus squarrosus and showed that the moss had a high uptake rate and high affinity for Cd, while the results are compared with data onCd uptake by the lichen genus Peltigera.

TL;DR: The morphological and physical characteristics of epicuticular wax of Maranta, Dieffenbachia, Chrysanthemum, Spathiphyllum, and Gerbera grown in a greenhouse, growth chamber, or in vitro, were determined by scanning electron microscopy (SEM) and gravimetric analysis.

TL;DR: Effet d'une defoliation sur les taux de fixation d'azote, leur retablissement au cours de la periode de croissance nouvelle and leur influence sur la regeneration du systeme photosynthetique.

TL;DR: Etude de l'effet du regime lumineux et de the concentration en substances de croissance sur la croissance and l'enracinement du cultivar de pommier «Akero»
