Abstract

One of efforts to increase tomato plant productions can be done by fertilization. Gandasil B was one of leaf fertilizer which can be used to fill P of plant so that it can increase the plant production. However, so far it has not been used for tomato plants. Therefore, it needs to do a research in order to find out the concentration and fertilization period of Gandasil B to tomato production. The research was conducted in Lowokwaru Village, Malang on March to August 2012. The research consisted of 8 treatment combinations, they are K0P1 (without treatment), K1P2 (1g/l per 1 week), K2P1 (2g/l per 1 week), K3P1 (3g/l per 1 week), K0P2 (without treatment), K1P2 (1g/l per 2 weeks), K2P2 (2 g/l per 2 weeks), K3P2 (3 g/l per 2 weeks). Each treatment was repeated four times.The research results can be concluded that there is concenration interaction and fertilization period to plant height at the age of 14 and 49 days after planting, leaves amount at the age of 14, 21, 28, 35, and 42 after planting, flowers amount at the age of 49 days after planting, branches amount at the age of 49 days after planting, and fruits amount. However, partially fertilization period treatment affects at flowering time, flowers amount at the age of 28.35 and 42 days after planting, and fruits weight.

Abstract

This research aimed to see the effect of the addition of NAA and BA into MS media for the development of cassava micropropagation, furthermore, the composition of the media was appropriate to produce the maximum number of cassava shoots. The study was conducted using a completely randomized factorial design consisting of 2 factors, namely: Factor I: the concentration of Naphthalene Acetic Acid (NAA) consisted of 2 levels, namely: 0 mg / l (N0) and 0.1 mg / l (N1). The second factor was the concentration of Benzyl Adenine (BA) consisting of 4 levels: 1.0 mg / l (B1); 3.0 mg / l (B2); 5.0 mg / l (B3) and 7.0 mg / l (B4). Apply 8 treatment combinations, N0B1; N0B2; N0B3, N0B4, N1B1; N1B2; N1B3; N1B4. Observations were made on the variables: time of shoot initiation, number of shoots, number of leaves, and percentage of live and contaminated explants until the age of 16 weeks after sub-culture. The results showed that there was no interaction between the addition of the auxin hormone NAA and the cytokinin BA into MS medium at the time of shoot initiation, but both hormones could support the number of new shoots and the number of leaves per plantlet. Media without the addition of NAA with the addition of BA 1.0 - 3.0 mg / l was able to initiate new shoots the fastest, namely 7-10 days. The best number of shoots of cassava (4.43 shoots/explant) used MS medium without the addition of NAA with BA 3.0 mg / l for 16 weeks (4 months) of culture.

Abstract

Alar is a growth regulator that in certain concentrations can inhibit growth, shorten stem segments, strengthen stems to improve the quality of tissue-cultured seedlings. This study aimed to determine the effect of alar and Benzyl Adenin (BA) on banana meristem multiplication. The experiment was conducted in Tissue Culture Laboratory, Faculty of Agriculture, Tribhuwana Tunggadewi University, Malang. The study used a Completely Randomized Design consisting of two factors, namely alar concentration (A0 = 0 mg/l and A1 = 1 mg/l) and BA concentration (B1 = 1 mg/l, B2 = 3 mg/l, B3 = 5 mg/l and B4 = 7 mg/l). Observations were made for 12 weeks of culturing with the observation variables: shoot initiation, number of shoots/explants, number of leaves, and shoot height. The results showed that alar and BA did not significantly affect the development of banana meristems. The use of Alar caused the banana plantlets to be shorter and sturdy, while BA affected the number of shoots produced. BA 1 mg/l was able to increase more shoots.

Abstract

Orchid is an ornamental plant, including the Orchidaceae tribe, which is widely favored among the ornamental plant community because it has high economic value, unique shapes, attractive colors and longer-lasting blooming flowers, one of which is a Phalaenopsis orchid. One of the efforts to accelerate the vegetative phalaenopsis can be done with the application of the NAA hormone and leaf fertilizers such as Gandasil fertilizer and Growmore fertilizer. The aims of this research to determine the effect of NAA, Gandasil and Growmore fertilizer types on the growth of hybrid Phalaenopsis orchids. The study was conducted at Greenhouse Jalan Tlogomas Kec. Lowokwaru, Malang City, for 5 months. The experiment was carried out using a factorial Completely Randomized Design (CRD) consisting of 2 factors namely, the factor I: NAA concentration: control 0 ppm (N0), 100 ppm (N1), 200 ppm (N2), and 300 ppm (N3). Factor II: leaf fertilizer, Growmore (P1) and Gandasil D (P2). Variables observed included: when buds appeared, leaf length, leaf width and percentage of live plants. The results showed that there was an interaction between the concentration of NAA and the type of leaf fertilizer on the emergence of shoots. When the fastest shoots appear at 100 ppm NAA, Growmore fertilizer (N1P1), which is 29 days. The NAA hormone influences the increase in leaf length and leaf width until 16 weeks of age. The best growth of hybrid Phalaenopsis was obtained at the administration of 200 ppm NAA with an increase in leaf length of 1.49 cm and an increase in leaf width of 1.06 cm until 16 weeks of age. Growmore and Gandasil D did not affect the vegetative growth of hybrid Phalaenopsis Orchid plants.

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
