When cane cuttings that have failed to germinate are dug up and examined, they are frequently found to be infested with the larvae and adults of Nitidulid beetles which, consequently, are often accused of responsibility for such failure. As additional evidence against them is adduced the rapidity with which replants may become infested in fields in which a high population of the beetles has bee...

two groups of olive cultivars were characterized as showing low (tokhmkabki) and high (roghani) rooting percentage after application of iba treatment. semi-hard wood cuttings were dipped in h 2 2 o 2 (0-3.5% w/v) and iba (4000 mg.l -1 ) and also they were investigated in combination. h 2 o 2 alone did not stimulate rooting of olive cuttings and there were no significant differences between this...

It is generally recognized that minute doses of substances which are toxic in larger quantities may act in a stimulatory fashion, that is, they may cause the plant to accelerate one or more of its activities in excess of any stoichiometric relationship. Minute traces of mineral salts (2, 4) and -auxins, bioses, vitamins, and other growth accessories (1, 3, 7) which are of biological origin, all...

using apple clonal rootstocks is necessary for improving crop efficiency in apple orchards. after graftingof apple cultivars on malling rootstocks, the extra parts of the rootstock was used as stem cuttings. apical,middle and basal parts of these shoots were used as cuttings. two propagation conditions, greenhouse andnursery and three concentrations of indole-3- butyric acid (iba) on rooting, c...

To establish an efficient regeneration system for Anthurium andreanum cv Rubrun, seeds from plant spadixes were germinated on a medium supplemented with 2.2 μ M BA. After 2 weeks, 74% of the seeds germinated and four weeks later, micro-cuttings from these plantlets were subcultured on a medium containing 4.4 μ M BA and 0.05 μ M NAA. On average, 3.6 shoots per explant were obtained. Four weeks o...

Plants can remove or immobilize various environmental contaminants; however, little is known about the physiological mechanisms underlying responses to soil amendment with biosolids contaminated with heavy metals. We investigated the responses of cuttings of hybrid poplar clones Eridano and I-214 grown for a season in soil amended with nutrient-rich organic material from tanneries, which contai...

Drill cuttings are considered representative of the lithology being drilled in a wellbore. However, the fragments that are two to three times larger and/or having odd shapes compared to the regular cuttings are commonly understood as cavings from the wall of the borehole and they are seldom of any help in compilation of a lithology. In fact, cutting description manual recommends ignoring cuttin...
