Abstract

The objectives of this research was leaning and finding the consentrade of IAA (Indole Acetic Acid) on vegetative growth of Phalaenopsis sp. The research used a randomly completely block design consisting of five treatments on level IAA consentration : 0 mg/l (A0), 100 mg/l (A1), 200 mg/l (A2), 300 mg/l (A3) and 400 mg/l (A4). Every treatment was replicated five times. The observed parameters included the amount of increasing leaves, the length and width of lives, the amount of increasing roots and the length of increasing roots. The results showed that the consentrade 400 mg/l IAA was the most appropriate consentrade to stimulated on vegetative growth of Phalaenopsis sp. The length of increasing leaves was 0,93 cm and the amount of increasing roots was 3,90

Abstract

Phalaenopsis is the most popular orchid for the consumer, because it has unique and interesting color, shape and size of flower and some flowers fragrant. One of the ways to improve the diversity of color and shape of the Phalaenopsis flower can be done by artificial mutation through gamma radiation. The study aims to determine the effect of Gamma ray radiation in Phalaenopsis phenotypes during vegetative growth. The experiment was conducted in two places; the implementation of radiation was carried out in BATAN Jakarta and then acclimatized in Green’s house of farmers in Bumiayu Village, Kedung Kandang, Malang in the months from January to June 2011. The experiment was arrange single Completely Randomized Design using dosage of gamma radiation treatment five levels: 0 krad (R0); 1.0 krad (R1); 2.0 krad (R2); 3.0 krad (R3) and 4, 0 krad (R4). Each treatment consist of fivereplication. The observations were made on the parameters of the number of leaves and the length and width of leaves at week 4, 8, 12, 16, the percentage (%) of plant life, color and leaf shape and the content of chlorophyll were measured at the end of the observation. The results show that the dosage of Gamma radiation influenced the number in leaves, the leaves color and shape, the amount of chlorophyll, but has no effect on the length and width of leaves at 16 weeks after radiation. The higher dose of gamma rays affected the vegetative growth slowest at dosage of 4.0 krad. Gamma ray dosage from 1.0 to 4.0 krad are able to produce color change in Phalaenopsis leaves

Abstract

This research was aimed at understanding and examining plantlet response to Kepok Banana in various doses of gamma ray radiation. Single Complete Random Planning was employed with 5 levels of gamma ray radiation doses. These five treatments comprised to 0 krad (A); 2.5 krad (B); 5.0 krad (C); 7.5 krad (D); and 10.0 krad (E). Every treatment had 5 replications. Each replication had 2 bottles such that 50 bottles emerge for a unit of experiment. The observation involved parameters such as shooting period, number of shoot, number of leaf, shoot height, plantlet stem, rooting period, number of leaf chlorophyll, and esterase iso enzyme tape pattern. Results of research indicated that gamma ray radiation doses affected its morphology characteristics (shooting period, number of shoot, number of leaf, shoot height, and number of leaf chlorophyll) and its genetic characteristics (esterase iso enzyme tape pattern from leaf). Dose of 2.50 krad gamma ray was able to produce mutant-based Kepok Banana shown by different morphology and genetic characteristics from original seed. Doses of 5.0, 7.5, and 10.0 krad gamma ray radiations had harmful effect on plantlet of Kepok Banana

Abstract

The objectives of this research were to study and to find out the influence of various liquidity in tissue culture’s media of banana toward the development of banana’ meristem, and to obtain a precisely coconut pond concentration in media of tissue culture resulted in the best plantlet. Treatments employed for this study comprised two factors. Liquidity of coconut pond as the first factor consisted of four levels, i.e. 0 % (A0), 7,5 % (A1), 15 % (A2) and 22,5 % (A3). Varieties of banana as the second factors consisted of Kepok (P1) and Ambon (P2). Parameters observed were initiation of rhizomes, number of rhizomes, number of leaves, root initiation, and number of roots. The results indicated that there were interactions between the liquidities of coconut ponds and variety of bananas during rhizomes initiation, number of leaves, period of root initiation and number of roots. The liquidities of coconut ponds in the concentration of 7,5 % and 15 % resulted in better rhizomes quality than other solutions. Whereas the liquidity of 7,5 % resulted in best quality of rhizomes initiation and number of leaves in Ambon variety. Best root initiation and number of roots was observed at 15 % liquidity of coconut pond treatment

Abstract

The research aimed to determine the type of foliar fertilizer and container for the flowering phase of lunar orchids. The study was conducted from November 2021 to February 2022, using a completely randomized design with two treatment factors and eight treatment combinations repeated three times. The combinations of these treatments are (a) Type of plastic container and Gandasil B leaf fertilizer 1 g/l (P1G1); (b) Type of plastic container and Gandasil B leaf fertilizer 2 g/l (P1G2); (c) Type of plastic container and Vanda's leaf fertilizer 1 g/l (P1G3); (d) Type of plastic container and Vanda's leaf fertilizer 2 g/l (P1G4); (e) Type of container for coconut coir and Gandasil B leaf fertilizer 1 g/l (P2G1); (f) Type of container for coconut coir and Gandasil B leaf fertilizer 2 g/l (P2G2); (g) Type of container for coconut coir and Vanda's leaf fertilizer 1 g/l (P2G3) and (h) Type of container for coconut coir and Vanda's leaf fertilizer 1 g/l (P2G4). Observations included parameters: number of leaves, leaf width, leaf length, when the stalk appears, stalk length, and number of flowers. The results showed that there is an interaction between the type of container and foliar fertilizer in supporting the flowering of Phalaenopsis sp. This type of coir container with Gardasil B fertilization of 2 g/l can produce flower stalks about seven months after transplanting and at the age of 8 months, the flower stalk length reaches 12 cm with the number of flower buds 2 – 3 buds per plant.

Abstract

This study aimed to identify and know the associated insects and their role in sweet corn plants. This study used a non-factorial randomized block design (RBD) with three kinds of treatment; yellow traps, net traps, and ground traps. Each treatment was repeated nine times so that there were 27 experimental units. In each treatment plot, the sample size is 3m x 1m. Sampling of insects on corn plants using net traps, yellow traps, and soil traps. The result showed that found 1,012 insects, from 8 Ordo and 25 families in sweet corn plants. In the vegetative phase found 636 insects in various roles. 408 insects are pests and 228 insects that are natural enemies. A total of 406 insects were found in the generative phase, 196 of which were pests and 210 were natural enemies.
