Effect of some phenolic compounds on growth and yield of two rice varieties. Parmar, Usha; Singh, Parmil; Malik, C. P. (Dep. Bot., Punjab Agric. Univ., Ludhiana, India). J. Res. (Punjab Agric. Univ.), 22(4), 725-8 (English) 1985. CODEN: JRPUAF. ISSN: 0048-6019. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Spraying 200 L/ha of 100 ppm R-salt (a monophenol; MPh) [135-51-3], 100 ppm RD-Brown (a diphenol) [103470-82-2], or 200 ppm H-acid (MPh) [90-20-0] increased the grain yield of rice of the medium-quality Palman 579 cultivar by 28.46, 24.1, and 13.6%, resp. RD-Brown and G-salt (MPh) [118-32-1] at 100 ppm increased the yield merely by 2.7 and 5.9%, resp., but the 1000-grain wt. increased from 20.33 to 26.2 and 29 g, resp. In the coarse variety Jaya, the max. increase in yield over control (43.08%) was with R-salt (100 ppm) followed by H-acid (100 ppm) (21.6%). The max. no. of spikelets per plant was obsd. with RD-Brown and R-salt. The 1000-grain wt. was highest in R-salt (100 ppm) and was neg. correlated with the no. of spikelets per plant.

Monoazo acid dyes

Monoazo acid dyes. Przybylski, Chrystian; Gmaj, Jan; Kujawski, Andrzej; Jablonski, Jerzy (Osrodek Badawczo-Rozwojowy Przemyslu Barwnikow "Organika", Pol.). Pol. PL 124174 B2 30 May 1984, 5 pp. (Polish). (Poland). CODEN: POXXA7. CLASS: IC: C09B029-00. APPLICATION: PL 81-229180 12 Jan 1981.Several substances like 134-32-7 may be metioned in this study. DOCUMENT TYPE: Patent CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) The title dyes I (R1 = SO3H, Me, Et, MeO, EtO; R2 = acyl, MeOCO, EtOCO, PhOCO; R3 = OH, NH2, substituted amino, all in o- or p-position relative to azo group; R4 = OH, NHAc, NO2; n = 0-2) contg. 31 SO3H group are prepd. by coupling diazotized R1- and R2-substituted m-phenylenediamine with the corresponding naphthalene deriv. The R1- and R2-substituted m-phenylenediamine is used as a replacement for carcinogenic 1-naphthylamine (II) [134-32-7] and gives dyes having good fastness and similar shades as II-derived dyes. Thus, 18.0 parts 5-acetamido-2-methoxyaniline [6375-47-9] was diazotized and coupled with 34.8 parts disodium 3-hydroxy-2,7-naphthalenedisulfonate [135-51-3] giving a dye [94099-33-9] dyeing polyamide fibers and leather in claret shades. .
