Kaurenoic and grandiflorenic acid, isolated from Wedelia paludosa (Asteraceae), some derivatives from these acids (alcohols, esters, amides, lactones, oximes) and other naturally occurring kaurane diterpenes were tested for their action on the growth of radical and shoot of Lactuca sativa. Gibberellic acid, GA3, a commercially available phytohormone, belonging to the same class of diterpenes, w...

The present investigation entitled Effect of plant growth regulators on the growth, yield and quality tomato (Solanum lycopersicum Cv. TMTH-234) was carried out at Horticulture Research Farm, Department Horticulture, Naini Agricultural Institute, Sam Higginbottom University Agriculture Technology Sciences, Prayagraj, Uttar Pradesh during Kharif in- 2022-23. experiment laid in a randomized block...

Micellar electrokinetic chromatography (MEKC) was developed as a method for quantitative determination of gibberellic acid (GA3) in fermentation broth and commercial products, using 25 mM disodium tetraborate as a buffer at pH 9.2 and 100 mM sodium dodecyl sulfate as a micellar phase. The baseline resolution (Rs of GA3 from other compounds in fermentation broth was achieved with Rs > 2.5. The a...

Plant growth studies involve seed germination studies and this depends on storage viability and dormancy aspects besides essential requirements and factors for the same. Of the various factors regulations plant growth and developmental processes intrinsic factors play a significant role. Plant hormones are chemicals that regulate plant growth. These occur in extremely low concentrations and inf...

To lower seed yield loss from directly harvested common bean or dry bean, height of the lower pod-bearing nodes needs to be raised. The objective of this greenhouse study was to stimulate lower stem elongation by gibberellic acid (GA3) of dry bean cultivars. Seeds of cv. Matterhorn, erect indeterminate Type II, and cv. Poncho, prostate indeterminate Type III, were dipped in GA3 at 62.5 to 16,00...

In China, the wild population of Nanjing Linden (Tilia miqueliana M.) is experiencing a drastic decline, primarily due to high levels empty seeds. This study aimed measure biochemical and physiological changes during fruit seed development in T. determine developmental mechanism. The weight method photosynthetic respiration were used biological aspects both fruits embryos, while transmission el...

Limes (Citrus aurantifolia Swingle) have a short postharvest life. Therefore, effective treatments increasing storage life to lengthen the time that produce remains fresh is desirable. This study evaluated effects of 1-methylcyclopropene (1-MCP), gibberellic acid (GA3), and Aloe vera on lime fruit quality. The optimum individual 50% coating, 300 mL·L−1 GA3, 750 nL·L−1 1-MCP were identified as m...

Abstract Obtaining high potato (Solanum tuberosum L.) tuber yield through increased number and weight of quality tubers is important for farmers while the quality factors are of interest for food processing industries. Potato processing industries require high quality tubers having the highest possible dry matter, starch and protein contents. A two-year field study was carried out as a factoria...
