The problem of generative propagation of soursop is its seeds take a long time to germinate which are caused by the hard seed coat. The solution to solve that problem is scarification and coconut water soaking to simply the process of imbibition and seed germination and also stimulate the growth of shoot. This objective of the research was to determine the effect of the scarification position and the soaking with various concentrations of coconut water on seed germination and growth of soursop seedling. This research was held at the Faculty of Agriculture field, the University of Sumatera Utara in March - July 2017. The research used a factorial randomized block design with two factors and three replication. The first factor is the scarification position (without scarification, stomach scarification, top scarification) and the second factor is coconut water soaking (0%; 25%; 50%; 75 %). The result of the research showed that the germination rate parameter, germination percentage, crop height, number of leaves, root volume and dry weight of crop significantly higher on without scarification treatment than with scarification treatment. The interaction between the scarification position and soaking with various coconut water concentrations was not significantly affecting the seed germination and growth of soursop seedling.

Salinity is a major abiotic stress limiting mungbean production worldwide including Indonesia. Since mungbean plant is very sensitive to salt condition, selection of salinity tolerant genotypes becomes important for mungbean improvement. The objective of this study was to evaluate the tolerance of eight mungbean genotypes to salinity at seedling stage under different levels. The experiment was arranged in a randomized complete block design with two factors (mungbean genotypes and salinity levels) and triplicates. Observation variables were germination percentage, vigor index, germination rate, hypocotyls length, epicotyls length, root length, number of root, seedling fresh weight, and seedling dry weight. The result showed that increasing level of salinity concentration inhibited the speed of germination, germination percentage, vigor index, normal seedling fresh weight, and number of lateral roots. Murai and Vima 1 were identified as tolerant genotypes, while Vima-2 and MLGV 0180 were identified as salinity sensitive genotypes at seedling stage. Currently, mungbean varieties with special characters, such as saline-tolerant is not yet available. The availability of saline-tolerant variety of mungbean is a cheaper and easier technology for farmers to anticipate the expansion of the saline area. The tolerant genotypes may be further tested at the later stage to obtain promising genotype tolerant to salinity that effectively assist mungbean breeding program.

Abstract This study aims to determine the effect of the application of plant growth regulators and osmoconditioning treatment to improve the germination of true shallot seeds. This research was conducted in Asam Kumbang, Medan Selayang, Medan, Indonesia. The research method was a Randomize Block Design with 2 factors, the first factor is Plant Growth Regulators (Z) with 6 levels, namely Z0 (Without PGRs Application), Z1 (Gibberellin 500 ppm), Z2 (Putrescine 15 ppm), Z3 (Putrescine 20 ppm), Z4 (Putrescine 15 ppm + Gibberellin 500 ppm), Z5 (Putrescine 20 ppm + Gibberellin 500 ppm). The second factor was the osmoconditioning treatment with Polyethylene Glycol (PEG) 6000 (O) with 4 levels, namely O0 (Without Osmoconditioning Treatment), O1 (PEG 6000 3%), O2 (PEG 6000 4%), O3 (PEG 6000 5%). Parameters observed were germination rate, germination rate index, percentage of germination, germination ability, simultaneous growth of seeds, seedling length, root length, seedling dry weight, and catalase activity test. The results of this study were: application of plant growth regulators could improve true shallot seed germination, indicated by the observed values of all parameters which were significantly different from those of the control (without PGRs application). The plant growth regulator that produced the best increase in germination was Gibberellins 500 ppm, although the difference in effect with other PGRs was not significantly different. Meanwhile, the osmoconditioning treatment with PEG 6000 was also able to improve the germination of true shallot seeds as indicated by an increase in most of the observed parameters, but in the root length parameter it was seen that the tendency of PEG 6000 3% always gave the highest value but gave the lowest value for this parameter. The best concentration of PEG 6000 in the osmoconditioning treatment to improve true shallot seed germination was 3%.

The influence of compost (derived from MSW and biosolids) maturity on seed germination of several weed species was evaluated. A bioassay was developed by extracting 20 g of compost of different maturities with various volumes of water, then measuring germination percentage of ivyleaf morningglory (Ipomoea hederacea) seeds placed on extract-saturated filter paper in a petri dish. A 20 g (dry weight) compost: 50 mL of water generated an extract that produced the widest percentage seed germination variation in response to composts of different maturity. Ivyleaf morningglory, barnyardgrass (Echinochloa crus-galli L.), purslane (Potulaca oleracea L.), and corn (Zea mays L) were selected as plant indicators to determine the compost maturity stage with maximum germination inhibition. Compost 8-week-old decreased percent germination, root growth, and germination index (combines germination rate and root growth), and increased mean days to germination (MDG) of each plant indicator. Immature 8 week-old compost extract effect on MDG and germination percent of 15 weed species was evaluated. Extract from 8-week-old compost inhibited germination in most weed species, except yellow nutsedge (Cyperus esculentus). Compost extracts derided from immature (3-day, 4-, and 8-week-old) compost resulted in delayed and reduced germination percent of important economic weed species.

An experiment was conducted to investigate the effect of different levels of cadmium (Cd) stress on germination, morphology, physiology and yield of rice. There were five treatments, viz. control (no Cd), 0.5 mM CdCl2, 1 mM CdCl2, 1.5 mM CdCl2 and 2 mM CdCl2, carried out by a randomized complete block design (RCBD) with three replications. Cadmium stress caused a significant reduction of plant height and tillers hill-1 in a dose-dependent manner. The highest decline of relative water content and SPAD value was found at 1.5 mM (11 and 16%) and 2 mM (14 and 19%) Cd stress compared to the control. The number of effective tillers hill-1, filled grains panicle-1, 1000-grain weight, length of panicle, grain yield and straw yield reduced significantly by 44, 32, 15, 24, 37 and 45%, respectively, over the control. Germination and seedling-related parameters were recorded 10 days after germination. The lowest germination percentage (27%), germination index (27%) and seedling vigour index (49%) were observed at the highest level of Cd stress in comparison to the control. Cadmium stress resulted in maximum abnormal seedlings and markedly reduced length of root and shoot as well as their fresh and dry weight. Root shoot ratio showed differential responses to Cd stress. Thus, it can be concluded that a higher level of Cd in soil has a detrimental effect on seed germination, morphology, physiology and yield of rice.

Alkalinity is one of the main limiting factors of seed germination in alkaline soils. The aim of this study was to evaluate the effects of Na2CO3 levels (0, 5, 10, 15, 20 and 25 mM) on seed germination, seed reserve utilization and seedling vigour of three local bitter vetch cultivars (Buinzahra, Shahreza and Tarom). The results indicated that increasing Na2CO3 concentrations caused a decrease in germination percentage (GP), germination rate (GR), seedling length, seedling dry weight (SLDW) and seed reserve utilization efficiency (SRUE). The rate of reduction in shoot length in comparison with the control in different concentrations of Na2CO3 was detected from Buinzahra as 30-92%, Shahreza 39-97% and Tarom 13-83%. Decrease in root length was more than shoot length in all the cultivars at each Na2CO3 level, as compared to the control. The weight of mobilized seed reserve (WMSR) and seed reserve depletion percentage (SRDP) decreased with increasing Na2CO3 levels up to 10 mM in Buinzahra and Tarom cultivars and up to 15 mM in Shahreza. WMSR and SRDP then rapidly raised with higher alkalinity levels. These results suggest that reduction of seed germination and decline in seedling dry weight in response to alkalinity stress is a consequence of decline in seed reserve utilization efficiency.
