ABSTRACT The kulo chrysanthemum variety is a North Sulawesi local variety characterized by large white flowers.  The new variety was introduced barely two years ago, yet it has gained considerable popularity among flower farmers in Tomohon City as well as in Manado, Tondano, and around the Minahasa and North Minahasa regencies. The growing interest in this particular variety has increased the demand for nursery stock resulting in a shortage of supply.  The conventional plantlet propagation method i.e. one seed to grow one plant, is deemed very time consuming and has poor plantlet yield.   It is therefore necessary to explore other plantlet propagation methods that can produce high yield in a relatively short period of time. One of the best techniques for plantlet propagation is tissue culture.  The success of tissue culture in producing high plantlet yield is determined by the use of appropriate plant growth regulators. Accurate concentrations of growth regulators are vital in achieving an optimum yield.  Consequently, determining the exact concentrations is a major issue in the tissue culture method.    Cytokinins are commonly used as growth regulators in shoot and plantlet propagations.  However, different types of cytokinins may have different effects on shoot generation from the nodal explants used in particular in vitro propagations.  The kulo chrysanthemum variety has never been propagated using the nodal explant tissue culture technique and may respond differently than other varieties.  Therefore, it is essential to determine which types of cytokinins are most suited to stimulate its shoot and plantlet propagations.

ABSTRACT This research aims to 1) Study the growth and yield responses of purple corn location effect of the seed source on the ear to growth and yield of, 2) Determine the right location of the seed source on the ear to get the best of growth and yield of purple corn. Research conducted at the Kebun Percobaan (KP) Pandu, Faculty of Agriculture, University of Sam Ratulangi (Unsrat) Manado from April to July 2016. The plant material used is purple corn collected in the laboratory of Plant Science, Faculty of Agriculture, Unsrat. This research is using a randomized block design by four treatments, such as: L1 (base of the ear), L2 (center of the ear), L3 (tip of the ear), and L4 (all parts of the ear). Each treatment consisted of four replicates so that there are 16 experimental units. The results showed that treatment of the seed source location on the ear gives no significant effect on all components of growth. The treatment of L4 (base of the ear) produces the highest percentage of plants grown for 14 days after planting (42.75%), treatment of L2 (center of the ear) produces highest of the plant height at 20 and 40 days after planting (6.17 cm and 45.68 cm). On purple corn yield components, the treatment provides a significant effect on the weight of ear and length of the ear, but no significant effect on the diameter of the ear, number of seed rows per ear and weight of 100 seeds. Treatment L2 (center of the ear) produces the highest yields on the weight of the ear (36.90 g), length of the ear (10.49 cm), diameter of the ear (2.92 cm), the number of seed rows per ear (7.55 lines) and weight of 100 seeds (24.56 g).

ABSTRACT The availability of nutrient inputs for soil fertility in forests is very important to preserve in an effort to anticipate a decrease in land productivity. Litter decomposition is a process of destruction of organic matter (litter) into nutrients available in the soil. This study aims to determine and compare the rate of decomposition of Palaqium obovatum, Spathodea campanulata, and Calophyllum soulattri litter in Bron Warembungan Forest, Minahasa Regency. This study was carried out on the leaf litter of Palaqium obovatum, Spathodea campanulata, and Calophyllum soulattri. The method of decomposition rate data collection using 36 litter bags placed randomly (with experiments using a completely randomized design (CRD) with two factors namely tree type and duration of decomposition) on the forest floor taken every week for four weeks, followed simultaneously with temperature measurements and humidity. The results showed that of the three main tree species in Bron Forest, the highest decomposition rate was shown by leaf litter of Spathodea campanulata with an average of 15.49% per week, followed by Palaquium obovatum (11.74% per week) and then Calophyllum soulattri ( 3.07% per week). The decomposition process in the three leaf litter took place very quickly in the first week which can also be associated with the results of measurements of water content in litter.Keywords: tropical rainforest, decomposition of litter, leaf litter
