The application of bioactive preparations during taking root of green cuttings conifers family of Cupressaceae has been described in this article. Longstanding experiments of growing planting stock with open and closed roots have been realized. Increase of taking root, apical growth and development of root’s system by positive influence of preparations has been shown

Green manure plants are increasingly being adopted for soil fertility improvement especially in low-input agriculture. Information on their reaction to plant parasitic nematodes is, however, scanty. Green manure plants, Calliandra calothyrsus, Canavalia ensiformis, Chenopodium quinoa, Crotalaria juncea, Desmodium uncinartum, Gliricidia sepium, Leucaena leucocephala, Mucuna pruriens, Tephrosia ...

A pulling effect by side roots is one way in which roots help to side in-plane strong of a little depth soil mass. In contrast to the effect of vertically-enlarge roots, whereby soil is strengthened by an increase in its shear strength, the pulling effect strengthens the soil by increasing the tensile strength of the rooted soil zone. To verify whether or not a pulling effect exists in the roo ...

We report the tissue-specific distribution of chitinolytic activity in Korean ginseng root and characterize two 31-kDa chitinolytic enzymes. These two enzymes (SBF1 and SBF2) were purified 70- and 81-fold with yields of 0.75 and 1.25%, respectively, and exhibited optimal pH and temperature ranges of 5.0-5.5 and 40-50℃. With [³H]-chitin as a substrate, K∧m and V∧max values of SBF1 were 4.6 mM a ...

The lectin of Azospirillum brasilense Sp7 at 40 μg ml-1 elicited two peaks of induction of nitric oxide synthesis in the roots of wheat seedlings after 3 and 26 h of coincubation. The lectin of A. brasilense Sp7.2.3, a mutant defective in lectin activity, produced the same effect, but the activation of nitric oxide synthesis in the roots was less in the case of 26-h incubation. Exposure to the ...

Micropropagation of black locust (Robinia pseudoacacia L.) was achieved by multiple shoot culture method. The high efficiency of this method suggests the possibility of its application. Initial explants, axillary bud meristems, were excised from one-year-old branches collected in early spring from selected trees aged more that five years. Common composed Aspen culture medium (ACM) with low con ...
