Abstract

Durian is a tropical native fruit from Indonesia with a distinctive flavor. Durian can be propagated durian generatively and vegetatively. Generative propagation of durian can be done by germinating seeds, which is vegetative propagation can be done by top grafting. Top grafting can be accelerated by the addition of plant growth regulators. Growth regulating substances in coconut water complex compounds are useful in differentiating cells. This study aimed to determine the effect of various concentrations of coconut water and the best type of grafting for the success of durian tops grafting. In this study was conducted in horticultural breeding centers Ranukitri Mojogedang Karanganyar April to September 2012. This research used Completely Randomized Design (CRD), which consisted of 2 types of treatment that top grafting, namely: cleft grafting, slash grafting, side grafting and coconut water concentration with 5 levels: 0%, 25%, 50%, 75%, 100% with 5 replications, so that the total treatment was 75. The results showed that the type of cleft grafting was the best grafting type to be used for the success of top grafting compared with other grafting types. Treating coconut water with a concentration of 25% was able to optimize the growth of durian top grafting than other concentrations.

Abstract

Daun duduk (Desmodium triquetrum L.) is a medicinal plant that has the power to treat hemorrhoids, but has not been widely cultivated. This research was conducted to obtain the right concentration and time interval of kinetin application to increase the growth of Daun duduk seedlings. This research was conducted from November 2019 until March 2020 at the Screen House, Faculty of Agriculture, UNS. The factors of the experiment were concentration of kinetin (0 ppm, 10 ppm, 20 ppm and 30 ppm) and the time interval of application (once every three months, once every 1.5 months and once a month). The parameters observed in this study were plant height, stem diameter, number of leaves, number of branches, number of roots, root length, fresh stover and dry stover. The results showed that the single factor of kinetin concentration could increase plant height, stem diameter, number of leaves, number of branches and dry stover. Meanwhile, the time interval for application and the interaction between the two factors did not have any significant effect. The most effective kinetin concentration in increasing the growth of Daun duduk was 30 ppm. Keywords: growth regulators; herbal medicines; plant height.
