Gladiolus is a potential ornamental plant to be widely developed because its high aesthetic value. Generally, gladiolus is propagated vegetatively by using tuber that called corm. There are some problems in gladiolus vegetative propagation, which is corm has a dormancy period and produces only one to two corms for each gladiolus plant. The effort that can be done to solve these problems is to provide benzyladenine to gladiolus corm. This study aims to determine the response of four varieties of gladiolus (Gladiolus hybridus L.) that soak to benzyladenine in increasing the growth of shoot and corm production. This research was conducted in Bandar Lampung in 2017. The treatment was designed factorially (4 x 4) using Randomized Block Design. The first factor was the varieties of gladiolus ie Anisa, Clara, Nabila, and Nurlaela. The second factor was the 100 ppm concentration of benzyladenine in repeating ie first, second, third, and fourth soaking. Data analysis was tested by Least Significant Difference (LSD) test at 5% level. The results showed that (1) from four gladiolus corm varieties, Nabila produced the highest number of shoots at 10,34 shoots, while the variety that produces the highest number of corm was Clara at 5,71 corms, (2) the benzyladenine that used up to four times for soaking the corm resulted the same response in increasing growth of shoot and corm production of four gladiolus varieties, (3) the response of each gladiolus varieties didn’t depend on how many times that benzyladenine used to soak the corm in increasing the growth of shoot and corm production of four gladiolus varieties.

<em>Tea (</em>Camellia sinensis<em> [L.] O. Kuntze) is one of priority commodities in West Java. Extensification of tea plantation in lowland and suboptimal areas is believed to contribute significantly in improving the farmers welfare. Temperature differences between the lowland and highland areas affects the metabolism of tea plants. In technical culture, centering (pruning) is required to form the shrub with ideal branching. This study aimed to determine cytokinin effects on the growth of tea plants after centering in the lowland areas. The experiment was conducted at the Experimental Station of Faculty of Agriculture, Padjadjaran University, Jatinangor, from November 2016 until June 2017 using 10 months old tea plant materials. The experiments used a randomized block design with 4 replications. The treatment used was cytokinin derived from coconut water with concentration of 25%, 50%, and 75%, cytokinin in the form of benzyl amino purin (BAP) with concentration of 60 ppm, 90 ppm, and 120 ppm, and control (without cytokinin). The results showed that cytokinin derived from coconut water or in the form of BAP applied in tea plants after centering, was only effective up to 3 months after application. At 1 and 3 months after application, 50% coconut water or BAP 60 ppm increased the length of stem diameter, number of leaves, shoot length, and number of shoots. Therefore, coconut water with 50% concentration or BAP 60 ppm can be used as source of cytokinins for tea plants in the lowlands after centering.</em>
