objective: in order to study the effect of different concentrations of iba hormone on rooting of olive cuttings in spring and winter of 2012-2013 in a greenhouse in jiroft, iran. methods: a split-plot experiment was conducted on the basis of a randomized complete block design in which hardwood cuttings of one-year-old olive plants cv. manzanilla with the diameter of 0.7-1 cm were used. the main...
ABSTRACT: Cedrela fissilis is a species of great genetic diversity, with low population density and seminal propagation, which causes difficulties in the vegetative propagation process. This research evaluated rescue stem cutting rooting originated from epicormic canopy sprouts C. fissilis. For this, induction was 52 days after complete girdling semi-girdling 20 40 cm ground, no treatment, duri...
BACKGROUND Cuttings and seedlings of Jatropha curcas L. were exposed to different regimes of lead (Pb) stress as Pb(NO₃)₂ at 0 (CK), 0.5, 1, 2, 3, and 4 mM kg⁻¹ soil. OBJECTIVES The effect of Pb treatment on the root length, tolerance index, photosynthetic pigments, photosynthetic activity, lipid peroxidation, and antioxidant enzyme was studied in a greenhouse pot experiment. RESULTS The re...
Single-node leafy stem cuttings of Shorea leprosula Miq. were subjected to a high, intermediate or low irradiance treatment for 16 weeks in an enclosed mist propagation system. Before rooting, maximum photosynthesis of the cuttings occurred at an irradiance of 400 micro mol m(-2) s(-1). Although none of the irradiance treatments affected the number of roots produced per cutting, the numbers of ...
in this research, possibility of bulblet production from different cuttings including leaf, leaf-bud and leafy-stem of lilium oriental hybrid cv. ‘star gazer’ evaluated under different levels of indole-3-butyric acid (iba) with 0, 250, 500, 750 and 1000 mg per liter (ppm). the cuttings were taken from stems which grown from cold treated bulbs in early october. a factorial experiment was done in...
In vitro pathogenicity tests demonstrated that Hirschmanniella caudacrena is pathogenic to Ceratophyllum demersum (coontail). Symptoms were chlorotic tissue, deformed stems, and, finally, death of the plant. Inoculum densities of 500 nematodes per 5-cm-long cutting in a test tube containing 50 ml of water resulted in death and decay of some of the cuttings within 8 weeks; 100 nematodes killed t...
We investigated the interaction between indole-3-acetic acid (IAA) and ethylene in the regulation of the seasonal periodicity of tracheid production in 1-year-old balsam fir (Abies balsamea (L.) Mill.) cuttings collected at different times during the dormant period. The cuttings were left with their buds intact or were debudded and treated either apically with IAA or 2-chloroethylphosphonic aci...
Physalis angulata L. grows as a wild plant in tropical areas of America, its center origin being undetermined, it is believed that the originated South American countries. In propagation by cuttings, auxins are necessary for formation adventitious roots. The objective was to evaluate different dosages IBA rooting development cuttings. Apical herbaceous cuttings with 10 cm size were used, submit...
Long, character-marked furniture cuttings are easily obtained when low-grade (2A and 2B Common) yellowpoplar lumber is first ripped into strips and then crosscut to remove objectionable defects. Overall yields of character-marked material using this procedure were 78 % from 1 Common and 2A Common and 70% from 2B Common yellow-poplar lumber. Furthermore, 82% of the 1 Common cuttings, 61% of the ...
Black willow (Salix nigra) cuttings are used for streambank stabilization where they are subjected to a range of soil moisture conditions including flooding. Flooding has been shown to adversely impact cutting performance, and improved understanding of natural adaptations to flooding might suggest handling and planting techniques to enhance success. However, data assessing the root aeration in ...
