Effect of potassium chlorate on flowering, total nitrogen, total nonstructural carbohydrate, C/N Ratio, and contents of cytokinin-like and gibberellin-like substances in stem apex of 'do' longan

The effect of potassium chlorate (KClO3) on flowering, total nitrogen (TN), total nonstructural carbohydrate (TNC), carbohydrate/nitrogen (C/N) ratio, and contents of cytokinin-like and gibberellin-like substances in stem apices of 'Do' longan were studied in CRD, with four treatments of K...

Wangsin T. Pankasemsuk Agricultural and Biological Sciences The effect of potassium chlorate (KClO3) on flowering, total nitrogen (TN), total nonstructural carbohydrate (TNC), carbohydrate/nitrogen (C/N) ratio, and contents of cytokinin-like and gibberellin-like substances in stem apices of 'Do' longan were studied in CRD, with four treatments of KClO3at 0, 200, 500, and 800 g/tree by soil application. There were three replications with one tree/replication. The results revealed that all KClO3-treated trees were flowering before the untreated trees. TN of all KClO3-treated trees tended to be higher than untreated ones. TNC of all KClO3-treated trees tended to decrease before flowering (1st-3rd week) then increase after flowering, while the untreated trees tended to decrease gradually. During flowering period (2nd-5th week), C/N ratios of all KClO3treated and untreated trees were not significant different (P = 0.05). The contents of cytokinin-like and gibberellin-like substances were determined by soybean hypocotyl and rice secondary-leaf-sheath bioassays. The results revealed that the stem apices from all potassium-chlorate treatments had higher contents of cytokinin-like substance and lower gibberellin-like substance than the untreated trees. © ISHS. 2018-09-11T09:21:07Z 2018-09-11T09:21:07Z 2005-01-01 Book Series 05677572 2-s2.0-33750992688 10.17660/ActaHortic.2005.665.29 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=33750992688&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/62032
