Abstract

This study aims to determine the vegetative growth of Dendrobium sp orchids at various concentrations of liquid organic fertilizer and fertilizer intensity. This research was designed with a completely randomized design (CRD) factorial pattern. The first factor is the concentration of liquid organic fertilizer consisting of three levels, namely the concentration of 5 ml / liter (A1), 10 ml / liter (A2), 15 ml / liter (A3), and the second factor is the intensity of fertilization consisting of 1 time / week ( B1), 2 times / week (B2), 3 times / week (B3). The results showed that the interaction between the concentration of liquid organic fertilizer and fertilizer intensity significantly affected the time parameters of buds, shoot height, and number of leaves. The 10 ml / liter concentration treatment with fertilizer intensity 3 times / week (A2B3) gave the fastest shoot growth of 7.93 weeks and had the highest yield on Dendrobium sp orchid shoot height at 12 weeks after planting which was 3.5 cm and the amount Dendrobium sp orchid leaves at the end of the observation were 4.75 strands.

Abstract

Dendrobium orchid has great potential to be developed. The problem faced in its development is the decrease of orchid productivity per square meter of cultivation area. Consequently, the less availability of orchid either in quality and quantity. Whereas, there are growth regulator substances might be used to fulfill the hormone needs of orchid to obtain optimal growth. The main constraint is how the growth regulator substance in a certain amount affected the dendrobium archid growth. The research objective is to assess the growth response of stem cuttings of Dendrobium secundum orchid in combination of concentration and application intensity of growth regulator. This research was conducted for 3 months from October to January 2018, at Orchid Green House of the Permanent Nursery of BPDAS Palu Poso, Tadulako University. The results of study showed that the best treatment was combination of NAA (1 ml) + BAP (1 ml)/liter of water applied once a week (P1), which gave the fastest shoot growth of 16.25 days and had the highest growth on the shoot height of 3.5 cm and on the leave number of 4 sheets at the age of 12 weeks after planting.

Abstract

Ebony (Diospyros celebica Bakh.) Has a local name as kayu hitam, which is one of the superior tree species in Sulawesi. Ebony wood has a very high economic value because in addition to the beauty of fiber and wood color, ebony also includes exotic species that have high strength and durability. Ebony regeneration rate in nature is relatively low, this is caused by its semi-tolerant nature, where at the ebony seedling level requires shade plants. In addition to shade, mulch also plays an important role in the initial growth process of plants, the use of mulch is able to maintain a more stable soil temperature and is able to retain moisture around plant roots. The research was conducted for 3 months, from December 2015 to February 2016. The research location was in the area of the Faculty of Forestry, Tadulako University, Palu, Central Sulawesi Province. The method used is a completely randomized design (CRD) factorial pattern, which consists of two factors, namely light intensity and type of mulch. The materials used in this study were 6-month-old ebony seedlings, topsoil soil, bokashi fertilizer. Observation of ebony plant growth shows that ebony needs shade at an early stage and requires mulch for the growth process, I1M1 treatment (70% light intensity + 1kg coconut shell charcoal mulch) produces the best height increase of 1.79 cm. The I1M2 treatment (70% light intensity + 1kg sawdust charcoal mulch), the best is 1.30 mm. The I2M1 treatment (90% light intensity + 1kg coconut shell charcoal mulch) did not dominate the growth of leaves much as well as the I2M2 treatment (light intensity 90 + sawdust charcoal) did not dominate the leaf area increase.Keywords: Eboni, light intensity, mulch.

Abstract

One of the obstacles in the cultivation of saga plant (Adenantherapavonina L)  was saga plant’s seeds (Adenantherapavonina L) have the high dormancy properties, it was caused by the hard seed coat which is impermeable to water. An effort to break the dormancy of the saga seeds coat (Adenantherapavonina L)  could be done by scarification. This research was located in PersemaianPermanen BPDAS Palu-Poso which is in the Tadulako University area, Palu, Central Sulawesi from June to August 2019. This research was used Completely Randomized Design (CRD) method with four treatments and ten repetitions. Each repetition consisted of five saga seeds (Adenantherapavonina L). So that the saga seeds needed were 200 seeds. The scarification treatment was given S0 symbol: Without scarification (control), S1: Soaking in a hot water with 100oC temperature for 10 minutes. S2: Cutting on cotyledons, S3: Sanding on all plants of seed surfaces. The treatment of various types of scarification of saga seed germinations (Adenantherapavonina L)very significant effect on germination that is germination, speed of germination and simultaneity of germination. The highest germination, germination speed and simultaneity germination in the S3 treatment, namely sanding on the entire surface of the seed coat.The germination rate of S3 treatment with the highest value was 0.95%. The speed of germination with the highest value was 0.03%. Simultaneity germinated with the highest value of 4.40%. Whereas the lowest germination, germination speed and simultaneity germination were found in S0, that is  without treatment (control) with a value of 0.00%.Keywords: Seed, Germination, Adenanthera pavonina L
