Pangal (Baccaurea bracteata Muell.Arg.) is a flowering plant belonging to the Phylanhace tribe know as fruit and wood producer. The pangal plant is native to debt, but its  existence is diminishing now. Therefore, it is necessary to procure seedlings for forest restoration with cuttings.  The purpose of this study was to obtain root stimulants and planting medium suitable for the growth of pangan shoot cuttings. This experiment used a (split plot) design with a completely randomized design (CRD). The main plot factor was the planting medium with two levels of factor (cocopeat (M1) and cocopeat with husk charcoal (M2)). The subplot factor consists of three levels of factor (control (Z1), rootone-F (Z2) and wood vinegar (Z3)). Each treatment was replicated  five times to obtain 30 units of treatments. The result showed the highest percentage of life (60%) was obtained by in cuttings that were treated with rootone-F and were planted in cocopeat medium and rice huck mixture. After being tested statistically, the effect of planting media (cocopeat or mixture of cocopeat and husk charcoal) and root stimulants (without root stimulants, rootone F or wood vinegar) was not significant to primary root length, primary root number, secondary root number, number of leaves and shoot length.  Keyword: Baccaurea bracteata, husk charcoal wood vinegar, rootone-F.

Germination percentage of common milkweed (Asclepias syriaca L.) seeds was low 1 mo after seed collection. Seed dormancy decreased with time at storage temperatures of −12°, 5° or 21 °C. After 11 months of storage, seeds stored at 21 °C had 15–18% higher germination compared to the seeds stored at −12° and 5 °C. The best seedling emergence was obtained at a temperature of 27 °C when seeds were planted at a depth of 0.5 or 1 cm. Seedling emergence was better in muck or sandy soil than in clay soil. Seedlings developed slowly up to 30 days after emergence at 15 °C under an 8-, 12- or 16-h photoperiod. High temperatures (27 °C) stimulated seedling growth under each photoperiod. Taller seedlings with more leaves, longer primary roots, more lateral roots and adventitious root buds grew at 27 °C as compared to 15° or 21 °C. Increasing the photoperiod from 8 to 16 h increased plant height and number of leaves but not primary root length.

An experiment was conducted during winter to find the effect of girdling, etiolation and auxins i.e. IBA and NAA on rooting of semi- hardwood cuttings of olive cv. Leccino under mist. The experiment comprised of 13 treatments and was combinations of girdling, etiolation and auxins. The results indicated that the best rooting characteristics viz; highest percent rooted cuttings (53.33), number of primary roots (6.58) and secondary roots (8.53) and diameter (0.46 mm) were maximum with cuttings treated with IBA at 5000 ppm, where as the maximum primary root length (5.30 cm) and secondary root length (2.42) was recorded with the treatment girdling + IBA 4000 ppm + NAA 1000 ppm and IBA 4000 ppm, respectively. Regarding the shoot characteristics viz; plant height (14.59 cm) was recorded highest for the treatment IBA@ 4000 ppm which was at par with the treatment IBA @ 5000 ppm (14.26 cm). Highest plant diameter (2.40 mm), numbers of leaves (16.26) and leaf area (36.42 cm2) were highest for the treatment IBA @ 5000 ppm. Survival percentage of cuttings (71.57 %) was also highest in cuttings treated with IBA @ 5000 ppm. It is concluded that IBA at 5000 ppm was found to be the best treatment for propagation of olive through semi- hardwood cuttings during winter.

Plant organ phenotyping by non-invasive video imaging techniques provides a powerful tool to assess physiological traits and biomass production. We describe here a range of applications of a recently developed plant root monitoring platform (PlaRoM). PlaRoM consists of an imaging platform and a root extension profiling software application. This platform has been developed for multi parallel recordings of root growth phenotypes of up to 50 individual seedlings over several days, with high spatial and temporal resolution. PlaRoM can investigate root extension profiles of different genotypes in various growth conditions (e.g. light protocol, temperature, growth media). In particular, we present primary root growth kinetics that was collected over several days. Furthermore, addition of 0.01% sucrose to the growth medium provided sufficient carbohydrates to maintain reduced growth rates in extended nights. Further analysis of records obtained from the imaging platform revealed that lateral root development exhibits similar growth kinetics to the primary root, but that root hairs develop in a faster rate. The compatibility of PlaRoM with currently accessible software packages for studying root architecture will be discussed. We are aiming for a global application of our collected root images to analytical tools provided in remote locations.

Despite increasing reports on the function of CCCH zinc finger proteins in plant development and stress response, the functions and molecular aspects of many non-tandem CCCH zinc finger (non-TZF) proteins remain uncharacterized. AtC3H59/ZFWD3 is an Arabidopsis non-TZF protein and belongs to the ZFWD subfamily harboring a CCCH zinc finger motif and a WD40 domain. In this study, we characterized the biological and molecular functions of AtC3H59, which is subcellularly localized in the nucleus. The seeds of AtC3H59-overexpressing transgenic plants (OXs) germinated faster than those of wild type (WT), whereas atc3h59 mutant seeds germinated slower than WT seeds. AtC3H59 OX seedlings were larger and heavier than WT seedlings, whereas atc3h59 mutant seedlings were smaller and lighter than WT seedlings. Moreover, AtC3H59 OX seedlings had longer primary root length than WT seedlings, whereas atc3h59 mutant seedlings had shorter primary root length than WT seedlings, owing to altered cell division activity in the root meristem. During seed development, AtC3H59 OXs formed larger and heavier seeds than WT. Using yeast two-hybrid screening, we isolated Desi1, a PPPDE family protein, as an interacting partner of AtC3H59. AtC3H59 and Desi1 interacted via their WD40 domain and C-terminal region, respectively, in the nucleus. Taken together, our results indicate that AtC3H59 has pleiotropic effects on seed germination, seedling development, and seed development, and interacts with Desi1 in the nucleus via its entire WD40 domain. To our knowledge, this is the first report to describe the biological functions of the ZFWD protein and Desi1 in Arabidopsis.

The influence of penetration resistance (PR), an easily measured indicator of soil strength, on the growth of Pinus caribaea var. hondurensis radicles and seedlings was investigated. Negative exponential relationships between PR and both radicle and primary root elongation were observed. All root elongation ceased at PR levels of 3.25 MPa. Tip diameters of radicles and primary roots were positively correlated with PR values up to 2.4 MPa, whilst numbers of primary roots, total root lengths and lengths of longest roots were all negatively correlated with PR. Hypocotyl elongation was also reduced by increasing PR, although the reductions occurred at higher PRs than those which inhibited root development. In contrast, primary shoot development was unaffected by PR levels which were sufficient to stop root elongation, but was reduced in soil with a PR of 4.8 MPa. There were significant family x soil type and family x PR interactions for radicle, hypocotyl, primary root and primary shoot development. 1f these interactions are correlated with performance in the field, then they may serve as useful indicators of family suitability to both soil type and high strength soils.

Rodent tuber (Typhonium flagelliforme (Lodd) Blume) is one of the medicinal plants used for anticancer treatment, but the information on the cultivation of the plant is limited. The objectives of this research was to study the effect of light intensity and concentration level of paclobutrazol on growth and yield of rodent tuber. This research was conducted at Puspiptek Serpong, Tangerang Selatan, Indonesia. This experiment arranged in a split plot design with three replications. The main plot is light intensity (35, 55, and 100%). The sub plot is concentration level of paclobutrazol (0, 50, 100, and 150 ppm). Paclobutrazol applied as soil drench at one month after planting. In each application 500 ml solution was used. Variables observed consisted of plant height, number of leaves, leaf length, leaf width, leaf and tuber fresh weight; and leaf and tuber dry weight. Data were analyzed using analysis of variance and Duncan Multiple Range test at 5%. The result showed that interaction between light intensity and paclobutrazol affected the whole observed variable. Dry weight of tuber under 35% light intensity was lower than those in other light intensity for all treatments of paclobutrazol. Full sunlight intensity showed better dry weight in all treatments of paclobutrazol. However the dry weight decreasing significantly at 150 ppm paclobutrazol, but still higher than those in 35% light intensity. Therefore, rodent tuber is better cultivated under full sunlight and 55% light intensity with 100 ppm paclobutrazol.
