Influence of six plant growth regulators on Spanish peanuts

Influence of six plant growth regulators on Spanish peanuts. Wu, C. H.; Santelmann, P. W. (Agron. Dep., Oklahoma State Univ., Stillwater, Okla., USA). Agron. J., 69(3), 521-2 (English) 1977. CODEN: AGJOAT. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemicals) The influence of soil moisture on peanut response to SADH (succinic acid 2,2-dimethylhydrazide) [1596-84-5] was examd. in a growth chamber. Effects of SADH, PP 528 (I) [50326-22-2], FMC 28979 [21342-85-8], mefluidide [53780-34-0], TIBA [88-82-4] and TD 6817 [64060-04-4] were also evaluated in the field. SADH reduced plant size of peanuts grown under the wet regimes but not under dry conditions. Av. peanut leaf area was not affected by SADH. However, SADH did increase the root wt. in both wet and dry conditions in the growth chamber. Peanut yields were not increased by SADH in any of the 3 years in the field. No plant growth regulators used at any rate at any growth stage significantly increased peanut yield. The redn. of plant size by SADH might be significant to irrigated peanuts or in high rainfall areas where rotting of peanut vines may take place.

Dry matter and flower formation in citrus cuttings as affected by Ga3, Alar and CCC sprays

Dry matter and flower formation in citrus cuttings as affected by Ga3, Alar and CCC sprays. Lenz, F. (Inst. Nutzpflanzenforsch.-Obstbau, Tech. Univ. Berlin, Berlin, Ger.). Gartenbauwissenschaft, 39(5-6), 533-7 (English) 1974. CODEN: GTBWAY. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemicals) Gibberellic acid (I) [77-06-5] (100 ppm) sprays decreased root and leaf dry wt., but increased shoot dry matter in lemon (Citrus limon), lime (C. aurantifolia), and kumquat (C. madurensis) cuttings. I promoted elongation growth and inhibited flowering in lemon. Alar [1596-84-5] (100 ppm) and CCC [999-81-5] (500 ppm) decreased dry wt. in roots, shoots, and leaves in all 3 species and decreased elongation growth in lemon. Alar and CCC increased flowering in kumquat, but had no effect on flowering in the other 2 species.
