Summary. The effect of temperature and light intensity have been studied in rela)t:on to the greening of etiolated corn (Zea mays cv. Pioneer 309-B) seedlings. Chlorophyll accumulation is rapid at h:gh temperature (280) under all conditions of light intensity. At low temperature (160), and particularly in combination with high light intensity (3000-4500 ft-c), the accumulation of both chlorophyll and carotene is inhibited.Low pigment content at 160 is not directly due to a block in the p:gment synthesizing mechanism, btut rather to the photodestruction of chlorophyll prior to its stabilization in the membrane structture of the chloro-plast lamellae. The parallel reduiction in carotene content a't high light intensity is probably a contributing factor, because of its role in proteciting chlorophyll from photodestruction. The greater severity of photo-oxidation of chlorophyll at low temperature in corn when compared w:th wheat, appears to be dtle to a slower rate of protochlorophyllide synthesis and subsequent esterification. Thtus in corn at 160 there is a prolongation of the photosensitive stage dturing chlorophyll synthesis. Photo-oxidation at 160 has also been shown to be a function of the incident light energy, with the photosynthetic pigments acting as receptors for their own destruction.In comparison with the behavior of corn, wheat seedlin!gs green rapidly at h:gh lig,ht intensity at both 160 and 280. This contrasting temperature response with respect to chlorophyll synthesis may underlie a ftundamental difference in adaptation of these 2 species to growth in the temperate zones of the world.Many tropical plants are uinable to grow at temperatures well above freezing (25) and often show revere symptoms of chlorosis and even death, when germ:nated and grown at tem'peratures between 10 to 150 (17). This behavor is in sharp contrast with the active growth of temperate zone species when exposed to the same temperature range.

A specific high temperature-induced deficiency of chloroplast ribosome formation, as indicated by the absence of chloroplast rRNA, has been observed in the leaves of light-or dark-grown seedlings of Avena sativa L., Hordeum vulgare L., and Triticum aestivum L. at certain temperatures between 28 and 34 C. While the growth of the leaves (size, morphology, total amino nitrogen content) was little affected by the elevated temperature, chlorophyll accumulation was strongly inhibited, amounting to only 2 to 20% of its content in 22 C-grown leaves which were used as a reference for normal development. The carotenoid contents were also lower but still reached at least 15 to 20% of the

“…Some of these effec1is on vegetative growth are probably mediated through variations in the supply of carbohydrates , particularly with changes in light intensity. Dry matter accumulation (Friend, Helson, and Fisher 1962a) and tillering (Mitchell 1953b) have .been postulated to be controlled in this manner. However, many plant responses to light, particularly to variations in photoperiod 01' spectral content, are derived from other reaction systems.…”

“…An approach to the problem of assessing the role of the varions mechanisms can be made through the study of plants growing in controlled environments. The most complete study of cereal growth in different light environments has been made with Marquis wheat by Friend, Helson, and Fisher (1962a, 1962b, 1964, who coupled the techniques of growth analysis with more refined growth measurements in assessing the effects of a wide range of environments. The present paper reports on a similar study with barley (Hordeum vulgare L. cv.…”

SummaryThe effects of variations in light intensity, photoperiod, and light quality on shoot dry weight, tillering, and leaf growth of barley (cv. Prior) have been examined in controlled environments. The rates of tillering and of dry matter production were primarily dependent upon the total radiant energy incident upon the plants. Tilleriug was unaffected by changes in the photoperiod (independent of light energy) or in the spectral composition of the light which profoundly affected apical development. At low light intensities, tiller buds on the main axis only elongated, whereas at higher intensities secondary and higher·order tillers were produced. The largest number of tillers was associated with the coieoptile node, and tiller production declined regularly with each successive node up the main axis.The rate of leaf emergence on the main axis was relatively insensitive to changes in light intensity. At higher intensities there was an accumulation of expand· ing but unemerged leaves as the formation of leaf primordia progressively outstripped the rate of leaf emergence. Mature leaf size and shape were determined by the inter· action of two control systems: a heteroblastic change from node to node linked with apical development and hence indirectly affected by the spectral composition of the light source; and a direct effect of light intensity in the short photoperiod, probably mediated through carbohydrate supply.
