Abstract

Mangosteen requires drought condition to induce flowering, however extending drought period might restrict the plant growth. Therefore, the response of mangosteen to drought stress needs to be studied. This research conducted on May to July 2017 using Randomized Block Design with one factor. The experiment comprised of 4 levels of polyethylene glycol (PEG 6000) treatment, i.e., PEG 0%, PEG 10% (-0.03 MPa), PEG 15% (-0.41 MPa) dan PEG 20% (-0.67 MPa) (m.v-1). The results showed that there is a dryness of the mangosteen leaves given PEG which occured slowly, starting from the edge of the leaves into the center of midrib. Water consumption was fluctuated until the end of experiment, which the highest was 33.33 ml per day in 0% PEG treated plant, then decreased until 10 ml per day in 20% PEG treated plant. Proline content increased from the first week to the third week after all PEG treatments. The highest proline content were found in 15% PEG (22.14 umol.g-1) and 20% PEG (23.46 umol.g-1) treated plants. Plant dry mass was low under water stress, and more severe stress resulted in more reduction of plant dry mass level. Water stress did not affect the N and Mg content significantly, but reduced P content in mangosteen seedling. Keywords: evapotranspiration, nutrient content, proline, water stress

Abstract

Produksi manggis dari tahun ke tahun mengalami fluktuasi yang cukup signifikan akibat terjadinya ketidakseimbangan fotosintat pada tanaman manggis. Pada saat on year buah manggis yang dihasilkan banyak namun berukuran kecil, sebaliknya pada saat off year buah manggis yang dihasilkan sedikit namun berukuran lebih besar. Selain itu, terjadi gugur buah yang cukup tinggi ketika on year akibat tanaman tidak mampu menopang buah yang sangat banyak. Penelitian ini dilakukan dengan tujuan mendapatkan informasi mengenai status nutrisi pada tanaman manggis sehingga dapat menjelaskan fluktuasi hara dan gula pada tanaman manggis selama satu periode panen. Hasil penelitian menunjukkan bahwa tanaman manggis memiliki rasio jumlah daun dan buah yang tinggi yaitu 142:1. Perubahan kandungan hara daun akibat perkembangan buah manggis paling utama ditemukan pada unsur K, Ca, B, Cu, Zn yang memiliki peran penting dalam proses pembentukan buah. Diduga terjadi hambatan translokasi gula pada fase awal perkembangan buah yang ditunjukkan oleh tingginya kandungan gula pada daun seiring dengan rendahya kandungan gula pada buah manggis. Kandungan glukosa dan fruktosa paling tinggi terdapat pada buah manggis yang memasuki fase pematangan buah.ABSTRACTMangosteen production fluctuates year by year because of imbalance nutrient in plant. Plant produces a lot of fruit with smaller size during “on season”, while few of fruit with bigger size during “off season”. On the other hand, the high fruit drop occurred when “on season” because mangosteen tree is not able to hold too many fruits. This experiment was conducted to obtain the information of nutrient status on mangosteen tree and explain the fluctuation of nutrient and sugar in one harvset period. The result show that mangosteen had a very high ratio between leaves and fruit, i.e 142:1. The changes of nutrient content during fruit development were found in potassium (K) and calcium (Ca), B (boron), Cu (copper), Zn (zinc) which have a critical role in fruit set process. Limitation of sugar translocation in the beginning of fruit development stage was occurred. It shows by the high content of sugar in leaves along with the low content of sugar in mangosteen fruit. The highest glucose and fructose content in mangosteen fruit was found on the beginning of maturation stage.

Abstract

Guava “Crystal” is one of Indonesia’s most popular varieties; its demand continues to increase, so it is important to examine methods to increase fruit production. This research aims to increase the flowering and fruiting of guava “Crystal” through branch-bending and application of biofertilizer. The results showed that pruning + bending significantly increased the number of shoots by 15.8%, shoot length by 11.16%, and leaf number by 15.09%. This treatment also increased flower number by 88.84%, fruit number by 77.9%, and double the fruit weight. Biofertilizers significantly increased vegetative growth in the form of the number of shoots (5.12%), shoot length (9.21%), and number of leaves (10.29%). Pruning + bending and biofertilizer did not significantly affect weight per fruit, fruit diameter, fruit volume, fruit firmness, total soluble solids, total titratable acids, and vitamin C content.

Abstract

Tomatoes are a widely produced and consumed fruit-vegetable belonging to the Solanaceae family. It contains minerals, vitamins, essential amino acids, sugars, and fiber. Micro-Tom is a wild-type cultivar from a cross between the Florida Basket and Ohio 4013-3 cultivars. Micro-Tom has two mutant types, the iaa9-3 and iaa9-5 mutants, which exhibit strong parthenocarpic properties. It is classified as a mutant tomato due to a mutation in the IAA9 gene, which belongs to the Auxin/IAA (Indole-3-Acetic-Acid) gene family and plays a role in suppressing the endogenous auxin signal transcription pathway. Using artificial light in cultivation techniques shortens the plant cycle and accelerates the juvenile phase. This study aimed to investigate the morphological, physiological, and production responses of Micro-Tom tomatoes to supplemental LED lighting. The research was conducted at the Leuwikopo experimental field of IPB University from March to November 2023. A completely randomized design was employed, with two factors (LED spectrum and Micro-Tom genotyping) and nine replicates. The study also examined the potential benefits of combining polychromatic and monochromatic light-emitting diodes (LEDs). The response of Micro-Tom tomatoes to artificial lighting with purple and white LEDs did not show significant differences in growth and production parameters. However, significant differences were observed between the tomato types, specifically between the Wild-type and the iaa9-3 mutant. No significant differences were found in LED treatment or Micro-Tom genotype for physiological parameters such as chlorophyll content and glucose-fructose levels. Regarding fruit quality, no significant differences were observed for parameters such as total soluble solids (TSS, Brix) to total titratable acidity (TTA, acidity), glucose and fructose, and malic acid. The LC-MS/MS analysis of leaves exposed to purple LED light revealed a profile dominated by secondary metabolites from the fatty acid compound group, suggesting the potential benefits of this lighting combination. In conclusion, using LED lights can accelerate the plant life cycle and shorten the juvenile phase, as evidenced by the first flower emergence, which occurred 20 days after transplanting (DAT) in the wild-type genotype and 16 DAT in the mutant genotype.

Abstract

Abiu fruit harvested at the fully-ripe stage typically exhibits a shorter shelf life compared to those harvested at the half-ripe stage. Despite the longer shelf life, those at the half-ripe stage are more susceptible to shriveling during storage, particularly on the green part. This study aims to mitigate shriveling and enhance the postharvest quality of abiu fruit through ethylene application. The treatments consisted of 2 ethylene application methods (1-second dip and 60-second soak) and 4 concentrations [control (0 ppm), 100, 200, and 400 ppm]. The fruit was stored at room temperature (26 ± 2°C and RH 82 ± 2%) after ethylene application. The results showed that the soak application can reduce shriveling by 31% and extending the shelf life by up to 2 days. Decreasing of shriveling incidence also found in the 100, 200, and 400 ppm ethylene concentration by 29%, 52%, and 52%, respectively which lead to extend the shelf life up to 4 days. The soaking method and 100 ppm ethylene concentration were the most effective among all treatments, which were able to reduce shriveling by up to 63% and extend the shelf life of abiu fruit by up to 4 days.

Abstract

Sweet corn is a horticultural commodity that is widely cultivated and consumed in Indonesia. This study aimed to determine the growth and yield response of sweet corn plants to the application of various doses of ammonium sulfate fertilizer. The research was conducted at Pasir Kuda Experimental Field, Bogor, West Java. This experiment used a randomized complete block design (RCBD)with a single factor, namely the dose of fertilizer application. Treatments were arranged in 4 levels of application, namely: (1) control, (2) standard NPK fertilization, (3) 0.5 dose of N, (4) 1,0 doses of N, (5) 1,5 doses of N, and (6) 2,0 doses of N. The results of this test indicate that the application level of ammonium sulfate fertilizers at the application level of 1,0 doses N fertilizer treatment can generally provide plant height, stem diameter, number of leaves, stover weight, cob weight with husk, cob weight without husk, production plot-1, and productivity which are statistically higher than the control treatment. The application of 1,0 doses N fertilizer treatment had Relative Agronomic Effectiveness (RAE) values that meet the requirements to pass the fertilizer effectiveness test, with the highest RAE value obtained in the application of 1,0 doses N fertilizer at 188%.
