“…Any conclusions must agree with the experimental evidence obtained from studies of other plant responses controlled by the same photoreaction (4,8,20,23). One of the more obvious of these hypotheses is that the far-red-absorbing form of the pigment might undergo thermal decomposition.…”

“…REVERSIBILITY: The far-red region of the spectrum, near 7350 A, was satisfactorily isolated from sources of relatively high far-red emittance such as the sun (8000 fc) or incandescent-filament lamps (800 fc) by a filter of two layers of 300-gauge red and two layers of 300-gauge dark-blue cellophane (20).

“…They were dissected 10 days after beginning of treatment. Interruptions were made near the middle of each inductive dark period with radiation obtained through two layers of red cellophane from 18 standard cool white, slimline fluorescent lamps (20). The unfiltered bank of lamps provided an illuminance of 1000 fc at plant level.…”

“…This duodirectional reaction was shown to be repeatedly reversible and to be independent of temperature. This same reversible photoreaction was also established for the control of flower initiation of Xanthium (3), cuticle coloration of tomato fruits (20) and photomorphogenic effects such as leaf expansion (8,12), hypocotyl elongation (8) and the disappearance of the plumular hook of dark-grown beans (26).…”

Action-spectrum studies have shown that such diverse light-controlled plant responses as flower initiation (1,17,18), internode elongation (2,8,19), leaf expansion (8,19), and seed germination (4,23) the dark period, two short-day plants, soybean (Glycine Max (L.) AMerr. var. Biloxi) and pigweed (Amaranthus caudatus L.), and two long-day plants, barley (Hordeum vulgare L. var. Wintex) and Hyoscyamus niger L., were tested for evidence of the far-red action. A brief irradiation near the middle of an inductive dark period of 13 hours for soybean and 12 hours for pigweed prevented initiation of flowers, whereas a similar interruption near the middle of a non-inductive dark period of 12.5 hours for barley and 12 hours for Hyoscyamus induced flowering. In each case a far-red irradiation immediately following the dark-period interruption with red reversed the effect of the red light (table I).PLANT 'MATERIALS: Studies into the details of the photoreversible reaction controlling flower initiation were conducted principally with the short-day plants cocklebur, Xanthium pensylvanicum Wallr. (X. saccharatum Wallr.) and Biloxi soybean.There is considerable confusion arising from personal variations in the choice of the specific name for this species of Xanthium. Wallroth (24) described X. pensylvanicum and X. saccharatum as distinct species and published his descriptions in the same journal on the same date. According to Section 10 of the

Flavonoicl synthesis is, in many plants, either promloted by light or (lepen(lent upoIn light (3). The nature of this light re(quirement appears to vary de-pending UpOnl the conmpounds ancl plant miiaterials being studiedl ( 15,17,19,21,23 ), and little is known regalrding the relationship between photoinduced sy-nthesis of these compounds and photoincluced growth an(l (levelopmlenit. In etiolated pea plumules, low intensity red light stimulates both leaf growth (20,25) ancl the procluction of an in(lole-3-acetic atcid oxidcase inhibitor (13). This inhibitor has quite recently been found to contain kaeempferol-3-triglucoside (KG) and kaemplpferol-3-(triglucosv-l-p-coumarate) (KGC) (9,10,18). Materials and MethodsSeeds of Pisum sativumll cv. Alaska, obtaine(d from Associate(l See(l Growers, Inc., New Haven, Connecticut, were sown in moist washed vermiculite in 10 X 10 X 10 cm polyethylene containers. Each container held about 30 to 40 seedIs. The seedlings were growin in darkness at 27 + 1°and were exposed to dinm green light in the (lark rooml for occasional inspection and again at the tinme of harvesting.Red light was supplied by redl fluorescent tubes (Sylvania, 15 w). The far-red light source consisted of five 300-w internal-reflector incandlescent lamnps, light from whiclh was filteredl through 7 layers each of redl and blue (lu Pont cellophane an(d about 8 cIm1 of water (8).

Der Gehalt der Kelchblatter von Physulis Alkekengi an Carotinoiden erleidet mit fortschreitender Reife und Jahreszeit betrachtliche Anderungen. a-Carotin und Physoxanthin treten erst in den reifenden Kelchblattern auf und nehmen standig zu. Entgegen den Befunden von L. CHOLNOKY und J. SZABOLCS findet sich freies Lutein in den grunen und verestertes (Helenien) in den gelben und roten Kelchblattern. Die Carotinoide mit P-Struktur nehmen mit fortschreitender Reife zu. Nach L. CHOLNOKY und J. SZABOLCS~) kommt in den Kelchblattern von Physalis Alkekengi kein Lutein (Xanthophyll) vor. Dies steht in Widerspruch zu Befunden von R. KUHN und H. BROCKMANN~), die bereits 1932 Lutein (auf Grund der charakteristischen Absorptionsmaxima) in den griinen Kelchblattern von Physalis Franchetti feststellten3). Wir konnten spater Lutein auch in den reifen roten Kelchblattern von Physalis Alkekengi nachweisen4).Um die Unstimmigkeiten sowohl iiber das Vorkommen von Lutein als auch uber das von Physoxanthins) in den Kelchblattern von Physalis Alkekengi zu klaren, haben wir die Wnderungen des Farbstoffgehaltes mit zunehmender Reife und fortschreitender Jahreszeit systematisch untersucht. Es war unwahrscheinlich, daB Witterungsverhaltnisse, Bodenbeschaffenheit u. a. auf die Bildung der Farbstoffe keinen wesentlichen EinfluB haben sollen, wie dies von L. CHOLNOKY und J. SZA-BOLCS 1) angenommen wird. Es liegen umfangreiche Literaturangaben vor, die die Beeidussung der Carotinoidbildung in verschiedenen Pflanzen durch auBere Faktoren behandelns).
