Abstract

It is crucial to improve the shallot (Allium ascalonicum L.) cultivation system on peatlands to increase the growth and production of shallots. One is the provision of Biostimulants derived from Kirinyuh (Chromolaena odorata L.) extract. This study aimed to determine the effect of Kirinyuh (C. odorata) methanol extract on the growth and yield of shallot (A. ascalonicum) and to determine the best concentration and application time of Kirinyuh extract to increase the growth and yield of shallots. This research was conducted from September to December 2020 at the Biology Laboratory and Greenhouse Department of Biology, Faculty of Mathematics and Natural Sciences, Tanjungpura University, Pontianak. The study used a completely randomized (CRD) factorial pattern with two factors. The first factor was the concentration of Kirinyuh extract, which consisted of 5 treatments (0; 25; 50; 75, and 100 mg/L), and the second factor was application time which consisted of 2 treatments (1 week and two weeks). The results showed that the combination of Kirinyuh extract concentration and application time had a significant effect on wet shoot weight, dry shoot weight, tuber quantity, wet tuber weight, and tuber dry weight but had no significant effect on plant height, number of leaves, wet weight of roots, dry weight, root and tuber diameter. The concentration of Kirinyuh extract and the best application time was 100 mg/L with an application time of 2 weeks.

Abstract

Black orchid plantlets have a relatively slow growth at the acclimatization stage. The growth of black orchid plantlets can be increased by giving biostimulants. Biostimulants are bioactive compounds, and when they are applied, they can increase plant growth. This study aims to determine the effect of biostimulant Gotu kola extract (Centella Asiatica L.) on the growth of black orchid plantlets (Coelogyne Pandurata Lindl.) at the acclimatization stage. The research was conducted at the Biology Department's greenhouse from September until December 2020. The study used a completely randomized design with a factorial pattern. The first factor is the concentration of biostimulants consisting of 5 levels, e.g: 0 mg/L; 25 mg/L; 50 mg/L; 75 mg/L; 100 mg/L. The second factor is the application time which consists of 2 levels: once a week and once every two weeks. The results showed that the application of biostimulant Gotu kola extract had no significant effect on plantlet height, leaf length, leaf width, number of leaves, number of tillers, and number of plantlet roots of black orchid in the acclimatization stage.

Abstract

One of the most important stages in the process of transferring in vitro cultured seedlings to their natural environment is the acclimatization stage. The acclimatization stage is a critical period in plant propagation. The factors that most influence the growth of in vitro seedlings in the acclimatization process are suitable planting media and the administration of biostimulants. This study aimed to obtain the best planting medium and type of biostimulant for the growth of black orchid plantlets at the acclimatization stage. The study used a completely randomized design with a factorial pattern with two factors, namely first factor: type of growing media with 5 levels of treatment (wood sawdust, coconut coir, cocopeat, rice husk, sugarcane dregs) and second factor: type of biostimulant (without biostimulants; Moringa oleifera extract; Centella Asiatica extract; and Melastoma malabathricum extract). The results showed that the highest percentage of plantlet survival (100%) in the early stages of acclimatization was shown in plantlets grown on wood sawdust and coconut coir media. At the advanced acclimatization stage, the type of biostimulant significantly affected the parameters of survival percentage, tiller height, average number and width of leaves, and average number and length of roots. Optimal planting medium and biostimulant type for advanced acclimatization orchid growth is a single treatment of wood sawdust media with a tiller survival rate (100%), the highest number of leaves (4.65 strands), most roots (8.4 strands).
