Abstract

A major challenge in the development of shallot seeds is the limited availability of qualified seed due to pathogen infection during the vegetative phase. The study aims to determine the effect of storage duration and paclobutrazol (PBZ) treatment to the resistance of shallots crop. The study was conducted at the Berastagi Experimental Fields, Vegetable Crops Research Institute in February to May 2017. The experiment was arranged by randomized block design with two factors. The first factor is bulbs storage duration, which is without storage and stored for 2 months. The second factor is PBZ treatment with levels ie 0, 0.5. 1, 1.5 and 2 mL/L. The observation parameters are the diseases percentage, diseases intensity, roots number, and roots length. The results showed that the shallot bulbs that singly stored had a significant effect on the diseases caused by Peronospora destructor, Alternaria porri, and Fusarium wilt with low percentage category. The PBZ treatment had not significant effect on all observation variables, but the interaction with 2 months storage duration had effect on root length at 60 days after planting (DAP).

Abstract

Maintaining the availability of high quality of seed on-time is one of the major problems in the production of large white ginger seed rhizomes (LWG). LWG seeds cannot be stored for a long period of time because it is easily wrinkled and sprouted during the storage. This study aimed to understand the effect of PBZ treatment time and concentration on the quality of LWG seeds during the storage. This study used a randomized square experimental design with three replications. The main plot is the time of application of paclobutrazol: 1) 4 months after planting (MAP) and 2)  5 MAP, and as subplots are five levels of PBZ concentration : 0, 100, 200, 300 and 4 00 ppm. The results showed the treatment of PBZ 400 ppm at 4 and 5 MAP was the best concentration in increasing the shelf life of LWG seeds: growth speed (4.8% / etmal ), seedling height (60.38 cm) and dry weight of seedlings (1.51 g) after stored for 4 months compared with no PBZ treatment.

Abstract

This study aims to determine the population and genetic parameters of population F3 result of selection pedigri red rice crosses Silopuk with Fatmawati Superior Varieties using Augmented Design. Silopuk cultivars with red and inlaid rice characteristics while Fatmawati varieties with characteristics of large grain size, high production, high grain number, early age and white rice. The crosses are expected to produce high, large grain size, large amount of grain, maturity and color of brown rice. This research was conducted August-November 2016 at UPT Farm Faculty of Agriculture Andalas University. The genetic material used is the seed of the generation of F3 (F3-5, F3-12, F3-55, F3-95, F3-118, F3-122) derivatives of red rice crosses Silopuk with Fatmawati and the seeds of the two elders as a comparison with the experimental method using Augmented Design. The results of this study indicate the F3 population character number of filled grains per panicle is higher than the two parents with a wide range and other characters are between the two parents. The phenotypic diversity of flowering age characters in the F3-122 family is (2,41) and 1000 weight of pithy grains in the family  F3-5 (2,31) ; F3-55(2,39) and  F3-95 (3,49)  relatively narrow.  However, heritability in the broadest sense and genetic variability for all characters ranges from moderate to high and narrow to broad. Estimated genetic progress with 5% intensity in F3 population has high criteria for all characters (age of flowering, harvest age, plant height, stem length, total tillers, number of productive tillers, total grain / panicle, percentage of filled grains / panicle , total grain weight / clump and weight of filled grain / clump) except panicle length characters and 1000 grain weight of filled grains. Differential selection of population F3 with 10% selection intensity based on 1000 grain weight of pith grain, plant height and total grain weight per hill obtained 31 selected individuals. Selected individuals will be forwarded to the F4 generation

Abstract

Red pitaya is getting more popular in Indonesia recently as one of high antioxidant sources with a promising economic value. However, the production of this CAM plant is restricted by low success percentage of its natural pollination and self incompatibility problems. Therefore, artificial pollination is required to overcome these problems and increase its yield. This study was aimed to evaluate the effect of pollination models towards the yield of red pitaya. This study was conducted using randomized block design with three pollination models applied into nine groups. Pollination models used were open pollination (P1), hand-self-pollination (P2) and hand-cross pollination (P3). Several floral-related parameters, including the elongation of flower bud, diameter of blooming flower, length of stigma, number and length of anthers, were assessed. Effect of different pollination models was also observed through some yield-related parameters, such as fruit weight, fruit diameter, fruit length, harvesting age and number of fruit sets. This study revealed that hand cross pollination produced the best yield performance showing 541.1 gram of fruit with 11.5 in length and 8.66 cm in diameter. Harvesting age and number of fruit sets showed no significant difference among those three pollination models.    Keywords: Pollination, red pitaya, yields, fruits, flowers

Abstract

Kapulasan is one of horticultural plants derived from tropical region that has significant economic value. One of the obstacles in cultivating the plant is that kapulasan has flowering type of androdioceus, i.e. the male and the female flowers are separated. Female flowers produce hermaphroditic flowers that can produce fruits while the male ones will not produce fruits. In the cultivation of the plant, it is very difficult to determine the female flowers if they are propagated by seeds. It takes up to 7 years to determine the nature of the flowering. One of the important steps that can be done is through a system of early detection using molecular marks. RAPD technique as a simple technique can be used to distinguish the characteristics. The results of the research show that of the 250 primers used, the OPM-09 primer produces female sex bands related to the controller of the female kapulasan plants of which the ribbon produced is 512 bp in size.

Abstract

Soybeans undergo rapid deterioration due to its chemical composition and unfavourable storage conditions. The objective of the research was to determine the length period of seed hidration and dehydration which is integrated with rhizobateri to viability and vigor of deteriorated soybean seed.  A completely randomized design with four replicates were used in this experiment. Seeds were treated with varied combination of hydration period in a rhizobacteria suspension and followed by dehydration time.  Data were analysed using the F-test and significant differences were further tested with Least Significant Difference at the 5% level. Results showed that the hydration and dehydration period of seeds in a rhizobacteria suspension improved viability and vigor of seed which have 59.5% initial germination percentage. The improvement was 12.28%, 0.56, 25.4% and 1.4 days for standard germination test, vigor index, first count test percentage and T50, respectively. The hydration for 60 minutes followed by dehydration for 60 minutes gave the best results on seed viability and vigor.

Abstract

The quality improvement of ramie, including inner and outer aspects are required to be developed to optimalize its production. Unlike horticulture and food crops, ramie cultivation is not constrained by the soil type. This study was aimed to evaluate the agronomical characteristics of three ramie clones in ultisol land. This study was performed using descriptive analysis method with purposive sampling by collecting 10 clumps per clone. Clones of fiber ramie used were Ramindo 1, Bandung A and Lembang A. All clones were planted in ultisol soil located in 350 m above sea level from September 2015 until March 2016. The highest fiber production was achieved from Ramindo 1 followed by Bandung A and Lembang A. The resulted fiber from all clones was considered as quality class II fiber marked by the nominal value ranging from 400-450. Bandung A exhibited the best quality of fiber with nominal value of 450. In terms of its chemical composition, fiber produced by Lembang A contained the highest cellulose (74.7%) with the lowest lignin content (3.6%).
