COMBINED EFFECT OF GROWTH HORMONES AND GYPSUM INDUCES SALINITY TOLERANCE IN WHEAT UNDER SALINE-SODIC SOIL

In recent decades effective regulatory role of phytohormones in plants in response to salinity has received considerable attention. However, their role acting in combination with gypsum still remain elusive. That is why, this two-year study was conducted to assess the effects of foliar application of salicylic acid and L-tryptophan with and without gypsum on wheat crop in a moderately salt affected soil with ECe : 4.71 dS m(-1), pH(s) : 9.18 and SAR: 31.82. Treatments detail is as under: – (A). Amendments 1: gypsum @ 50% GR, 2: without gypsum, (B). Plant hormones T-1: control, T-2: SA @10(-5) M, T-3: L-TRP @10(-5) M, T-4: SA + L-TRP (each @10(-5 )M in 1:1). Results indicated that growth and yield parameters were higher in T4 (SA+L-TRP @ 10(-5) M in 1:1 ratio) with gypsum application @ 50% of GR. Individual application of either salicylic acid (SA) or L-tryptophan (L-TRP) improved the yield in comparison to control but the effect was more remarkable with their combined application. Post-harvest soil analysis clearly demonstrated that gypsum application improved the physical and chemical properties when compared to without application of gypsum. Results highlighted that salinity tolerance of wheat crop was increased in most of the studied parameters when these plant hormones were applied in combination, indicating a positive interaction between salicylic acid and L-tryptophan in salinized conditions.

Divergent and Orthogonal Approach to Carbazoles and Pyridoindoles from Oxindoles via Indole Intermediates

The previously unexplored Grignard addition to oxindoles provides a regiospecific approach to 2- and 2,3-disubstituted indole derivatives in high yields via a one-pot aromatization driven dehydration pathway. This method allows a convenient preparation of diallyl indoles that are used as ring-dosing metathesis (RCM) precursors for the orthogonal synthesis of pyrido[1,2-a]indoles and carbazoles. The synthetic utility of this method is illustrated by the synthesis of a microtubulin inhibitor and naturally occurring carbazole alkaloids.

Oxidative Pictet-Spengler cyclisations through acceptorless iridium-catalysed dehydrogenation of tertiary amines

The valuable tetrahydro-beta- and gamma-carboline skeleta can be accessed through Pictet-Spengler cyclisation initiated by acceptorless dehydrogenation of saturated cyclic amines. The substrate scope for the beta-isomers is found to be somewhat limited, but access to the gamma-isomers through the more reactive 2(aminoethyl)indoles is more general.
