<p>ABSTRACT</p><p>Pohpohan (Pilea trinervia Wight.) is one of indigenous vegetables that grows in the mountain areas of West Java. Propagule availability in large quantities and in a short time can be done with cuttings. However, propagation of Pohpohan by cutting  has  not  been  developed  presently.  The objective  of  the research was  to  obtain  the  best  plant  age,  stem  part,  and growing media  for the growth  of  pohpohan  stem  cuttings.  The  research  was conducted  at the Center  of  Tropical Horticulture Studies Experimental Field Tajur-Bogor, from January to July 2013. The cuttings were taken  from  mother plants  of  3,  4, 5,  and  6  months,  then the  cuttings  were  cut  to  stem tips  (B1), central stem  (B2),  and  stem  base  (B3).  The  were  five  cuttings  per experimental  unit. Experiment were replicated 3 times. Cuttings  were planted in polybag containing topsoil media (M0), rockwool (M1), husk  and  compost (M2),  and  vermicompost  (M3).  The  experiment  was  arranged in Randomized Completely Block Design.  Result of experiment  showed that pohpohan from 4 monthmother plant cut  at  stem  base  grow  in husk and compost  grow  best  (99.06% of living percentages, 100% percentage of rooted cutting  and 11-12 number of leaves).  The cutting of stem tips grown  in husk and compost showed the highest mean for the increase of stem length, 3.94 cm. There were no interaction between growing media of stem cuttings and part of stem in the growth of shoot height, number of branch, leaf width, and diameter of stem. Key words: growing media, indigenous, pohpohan, stem cuttings ABSTRAKPohpohan  (Pilea  trinervia  Wight.)  merupakan salah  satu sayuran  indigenous  yang  banyak tumbuh  di  daerah  pegunungan Jawa Barat.

Abstract Four ground covers were compared with bare soil for their effects on the growth of irrigated poplar trees from 1997 through 1999 at the Malheur Experiment Station near Ontario, OR. Stem cuttings of hybrid poplar (Populus deltoides × P.nigra , clone ‘OP-367’) were planted in April 1997 at a 14 × 14-ft spacing. Ground cover treatments consisted of (1) bare soil maintained with a preplant herbicide and cultivations, (2) mowed weeds, (3) wheat (Triticum aestivum) between tree rows, (4) alfalfa (Medicago sativa) between tree rows, and (5) squash (Cucurbita maxima) between tree rows. The field was irrigated uniformly using micro sprinklers along the tree rows. Wood volume at the end of September in 1997 and 1998 was significantly greater for the bare soil than any ground cover. By the end of September 1998, wood volume in bare soil plots was more than 100% greater than in mowed weed plots, and almost 50% greater than in squash plots. During the third growing season, the incremental growth of wood volume was similar among the bare soil treatment, mowed weeds, and the plots that had previously been planted to squash but remained bare in the third year due to closure of the tree canopy. Without consideration of the economic value of cover crops, results suggest that, in eastern Oregon, poplar wood volume during the first three years is the greatest when the ground is kept bare.West.J.

AbstractCommon cottonwood-based agroforestry system is widely adopted in Indian Indo-Gangetic plains. The stem cuttings of common cottonwood are raised in a nursery 10 to 12 months in rows spaced 0.5 mx0.5 m, before re-planting in the field. The longer duration of 10 to 12 months and wider spacing of stem cuttings in the nursery makes the entire transplants highly vulnerable to weed competition, especially during early establishment stages. The efficacy of preemergence herbicides and plastic and straw mulches for weed management in common cottonwood nursery was investigated at two sites in years 2014 and 2015. The major weed flora in the experimental field consisted of three grass weeds (crowfootgrass, feather lovegrass, and southern crabgrass), and four broadleaf weeds (scarlet pimpernel, garden spurge, niruri, and lesser swinecress). The integrated use of pendimethalin or alachlor applied PRE with paddy straw mulch significantly reduced density and biomass of both grass and broadleaf weeds compared to herbicide or straw mulch used alone, and provided similar level of weed control to hand weeding at both locations. Spreading of plastic mulch in the whole field after punching holes for common cottonwood stem cuttings, or in row spaces recorded similar weed control to hand-weeding. The integrated use of herbicides with straw mulch, and or plastic mulch alone significantly improved plant height, stem diameter, below- and above-ground biomass of common cottonwood plants compared to unweeded check. The study concluded that integrated use of herbicides plus paddy straw mulch or plastic mulch alone could be adopted for weed management in common cottonwood nursery plantations.

Carbohydrate Utilization

The relationship between the rooting patterns of five poplar hybrids and stem carbohydrate dynamics was investigated to determine if the availability or metabolism of carbohydrates was limiting early root production of cuttings. Differences in early root production (i.e., number, length, and dry weight) after 17 days paralleled the subsequent differences in accumulation of aboveground biomass that were observed when two Populus balsamifera L. × deltoides Bartr. (Jackii 4 and Jackii 7) and three Populus deltoides Bartr. × nigra L. (DN 2, DN 22, and DN 15) hybrids were compared. Total root length and dry weight of Jackii 4 was four times that of Jackii 7. Both DN 2 and DN 22 had a total root length twice that of DN 15. Rooting characteristics may be useful criteria for selection of productive clones. Carbohydrate analysis of stem cuttings suggested that hybrids differing in biomass production displayed different patterns of carbohydrate utilization. The concentrations of glucose and myoinositol declined more in faster growing hybrids (Jackii 4, DN 2, DN 22) than in slower growing hybrids (Jackii 7, DN 15). The results suggest that faster growing hybrids consume monosaccharides in growth processes, whereas the slower growing hybrids convert monosaccharides into alternative storage forms and use less in growth processes. The initial myoinositol concentration in stem cuttings of poplar hybrids was correlated (r2 = 0.95) with root dry weight produced after 17 days, but the initial starch concentration was unrelated to later root biomass production. The results suggest that initial myoinositol concentration in cuttings may be used in early selection for rooting performance.

Six-week-old uniform cottonwood seedlings (clones G-48 and Kranti) were raised from stem cuttings and subjected under two different water regimes (full and half field capacity) up to 60 days under open field conditions. The higher and lower regulations of physiological responses were triggered in case these seedlings irrigated up to their full and half-field capacities. The enhanced A value was observed from 13–19 and 12–14 μmol m-2s-1 in clones G-48 and Kranti after subjecting them under irrigation to the level of full field capacity. The withdrawal of irrigation to the level of half field capacity could reduce these values (≤50%), significantly. The decreased CO2 assimilation during drought stress was found to be correlated with decline in transpiration, largely regulated by stomatal dynamics to restrict CO2 diffusion, which also impaired carboxylation. Upon experiencing drought, the progressive loss in maximum quantum yield of photosystem II photochemistry (Fv/ Fm) and CO2 assimilation was found to be correlated with the loss in transpiration in both these clones. Consequently, the study reveals that irrigation to the level of half field capacity for a period of 60 days impaired agronomic traits viz., plant height, number of leaves, leaf area expansion, specific leaf area, relative water content, biomass, and harvest index, significantly. It also concludes susceptibility of clones G-48 and Kranti toward drought in relation to plant performance (i.e., CO2 assimilation, Fv/Fm, and biomass yield).

Abstract Vegetative propagation of superior genotypes via stem cuttings depends on their development of strong vigorous root system. Fourteen characters of cutting rooting were examined in multiannual tests with 12 genotypes of eastern cottonwood (Populus deltoides BARTR. EX MARSH) in course of evaluation of their utilization in selection tests. Variability and relationship among examined characters, and cutting survival rate were analyzed according to contribution of expected variances to the total variance and results of principal component analysis, stepwise regression analysis and path analysis. Along with total number and length of first-order roots, the characters that are regularly used in the assessment of rooting potential, our results signify dynamic shoot growth and uniform arrangement of roots on cutting at the beginning of growing period. The best results were obtained for shoot height at the second half of May. A rapid and non-destructive way of shoot characters’ measurement allows testing of larger material and prevents losses in propagation material of interesting genotypes. Alone or together with total root number and length these alternative characters could be used for the improvement of selection tests and procedures for cultivar technology design.

Randomized Design

The farmers have widely used vegetative propagation of plants due to the low germination percentage of seeds of various plant species. So to study the asexual propagation technique of Populus deltoides, the present study was conducted where a number of stem cuttings of Poplar were treated with growth hormones: IBA (Indole-3-butyric acid), NAA (1-Naphthaleneacetic acid) and GA3 (Gibberellic acid) at different concentrations (100 ppm, 200 ppm and 300 ppm). Some cuttings, which were not treated with hormones, considered as control. A completely randomized design was used to conduct the experiment. The responses were recorded for the cuttings, which were collected and planted in on-season (February) and off-season (July) for 30, 60 and 90 Day after planting (DAP). The results showed that the cuttings collected and planted in February month responded with the better growth rate in shoot and root parameters. The untreated cuttings showed relatively lower values for all growth parameters than the cuttings treated with hormones. Tukey HSD test of multiple comparisons revealed that IBA, at higher concentration, had significantly (P<0.05) higher values for most of the growth parameters, followed by GA3. Pearson product-moment correlation showed a very strong correlation (P>0.70) recorded for underground biomass and other parameters. These findings can allow the farmers to select the best treatment to enhance the growth and yield of P. deltoides.
