Abstract

Flooding is the presence of ground water (or other root media) that exceeds the capacity of the field. There are two physiological effects of flooding include : 1. The primary impact of the stress of water shortages due to a potential decline in water, and 2. Secondary effects of stress that is the gaseous stress and ions stress. Ion stress caused by the loss of mineral nutrients, while the gas stress in plants by flooding, there are three causes of the lack of oxygen, excess carbondioxide and excess ethylene. Lack of oxygen is divided into two, namely a state where no available oxygen is called anoxia, and the circumstances in which oxygen is available but it was not normal is called hypoxia. The presence of oxygen deficiency on rhizosfere will cause damage to the plants growing on it. This damage is caused by a disturbance in metabolic processes such as photosynthesis, respiration, carbohydrate distribution, loss of mycorrizae, interference with absorption of nutrients, hormonal disorders, enzymatic activity, the emergence of toxic anaerobic metabolites that would result in the disruption of plant growth. While the impact of excess carbon dioxide in the state were flooding including the accumulation of toxins such as asetaldehide and ethanol. High concentrations of carbondioksida encourage the activity of catalase, nitrate reductase and glycolate oksidase.

Abstract

Except for economic motive, consideration of special consumer demand such as diabetes patients has been increased utilization of sweeteners. But for healthy porposes, the sweetener must be natural, non toxic, low calorie and stable during process. Stevia is a sweetener which have that requirements. In recent year, there are stevia pure derivative products in the market but in high price so has not been used by small industries. Therefore, this study was aim to optimize utilization of stevia through simple extraction to produce sweetener for starfruit juice as small industry product. The research were divided to four step, they were determining of stevia leaves preparation, determining of extraction methode, determining of cold storage effect and determining of appropriate stevia concentration. The result showed that neither pH nor total soluble solid of starfruit juice were change by addition of stevia. According to organoleptic test we knew that dry leave of stevia was sweeter than fresh one when extracted in boiling water over 20 minutes (dry leaves:water is 1:100). Then, this liquid consentrate must be stored in refrigerator over 18 hours to raise the sweetness. The best concentration for starfruit juice was 1% liquid concentrate which combined with 8% sucrose.

Abstract

The research aimed to get the most suitable media and foliar fertilizer to acclimate plantlet of orchid hybrid resulted from inter generic crossing of Phalaenopsis sp vs Vanda tricolor and to study the difference of the chromosomal structure compared to their parents. The research showed that the best growing media for hybrid seeds of ♀ Vanda tricolor x ♂Phalaenopsis Pinlong Cinderella was pakis, the most suitable fertilizer was Hyponex 2g/l, number of parental chromosomes of Vanda tricolor 2n = 38, while Phalaenopsis pinlongcinderela; Phalaenopsis Joane Killeup June; the hybrid of ♀ Vanda tricolor x ♂ Phalaenopsis joankileup june) and the hybrid of ♀Vanda tricolorx ♂Phalaenopsis Pinlong Cinderella had the same chromosomes, 2n = 40. The chromosome size of V. tricolor ranged (1,94 ± 0,16) µm to (4,72 ± 0,19) µm, while Phalaenopsis Joane Killep June ranged (0,84 ± 0,02) µm to (2,97 ± 0,13) µm, Phalaenopsis pinlong cinderela was from (2,02 ± 0,15) µm hingga(5,91 ± 0,78) µm, the hybrid of ♀Vanda tricolor dengan ♂ Phalaenopsis joankileup june.) was from (1,77 ± 0,20) hingga (1,69 ± 0,24) µm, the hybrid of ♀Vanda tricolor dengan ♂ Phalaenopsis pinlong cinderela)was from (1,86 ± 0,03) µm to (6,74 ± 0,59) µm. The caryotype arrange-ment was also different. Vanda. tricolor 2n = 18 m + 1 sm, Phalaenopsis joankileup June 2n=13 m+7 sm., Phalaenopsis pinlong cinderela 2n = 18 m + 2 sm, while the hybrid of ♀Vanda tricolor x ♂ Phalaenopsis Joankileup june.) and the hybrid of ♀Vanda tricolor dengan ♂ Phalaenopsis pinlong cinderela) had the same karyotype, 2n = 17 m + 3 sm.

Abstract

The object of this research was examine to determine the effect of application Trichoderma sp and Hot Water Treatment (HWT) on the resistance and health of sugarcane seed buds. Reproduction of Trichoderma sp. performed in the laboratory center of Protection plantation Central of Java in Salatiga, Buds cip of seeds from garden in Boyolali. Multiplication in the green house of Protection Laboratory analysis at the Faculty of Agriculture Development, University of Tunas Pembangunan Surakarta. The experiment was arranged in a completely randomized factorial design, consisted of two factors. The first factor was Trichoderma sp inoculation wich were T1 = 25 g and T2 = 50 g and not inoculation of sugarcane seedling. The second factor was variation of plant hot water treatment, which were P0 = 0 minute, P1 = 30 minute, P2 = 60 minute, and P3 = 90 minute. Each treatment was repeated three times and each replicate consisted of 10 plants. The result showed that that the inoculation of Trichoderma sp. 25 g and variations hot water for 60 minutes increases the resistance and health of sugarcane seedlings show that increase plant growth of sugarcane seedlings variety 864.

Abstract

The study aims to know the efectivity of sterilization and the efficiency of Morashige Skoog media on the growth of Aloe vera L. explant, has been done in tissue culture laboratory, Faculty of Agriculture Sarjanawiyata Tamansiswa University. The experiment is factorial 4 x 3, arranged in a Completely Randomized Design with three replication. The first factor was sterilization methode (S) consist of four levels, those are: sterilization methode 1 (S 1), methode 2 (S2), methode 3 (S3), and methode 4 (S4). The second factor was concentration of MS media consist of three levels those are : full media (M1), ½ media (M2), and ¼ media (M3). The variables observed were : date of shoot emerge, number and height of shoots, number of leaves and roots, root length, shoot and root fresh weight, shoot – root dry weight and viability potensial of the explant. The result of analysis uses analysis of varians on the significant level 5%, and continued with Duncan’s Multiple Range Test significant level 5%. The conclution of experiment are interaction between sterilization 3, 4 methode, and full and ½ media concentration on viability of explant variable observed. The better of explant growth was gained the efectivity on alcohol of 96% and hyphocloric of 50% as long as 3 minutes sterilization methode, likewise the better of explant growth was gained the efficiency on ½ consentration MS media treatment.
