In this study, genetic variation in polycyclic growth was investigated a young Pinus brutia Ten. study Turkey. The number of flushes partially under additive control and moderately correlated with the tree height at age 4. is most economically important species Previous limited studies suggested that its cyclic shoot elongation pattern can be useful for selecting seed sources breeding conservat...

shoot tips from actively growing, greenhouse maintained plants of kalanchoe blossfeldiana were cultured in vitro for shoot proliferation and root initiation on murashige and skoog (ms) basal medium supplemented with naa and ba, both in concentrations of 0.00, 0.50, 1.00 and 2.00 mg l-1. results showed that the maximum plantlets height (7.012 cm), node number (4.516), root number (8.860) and roo...

the effect of tricyclazole application on waterlogging damage alleviation in canola seedlings was evaluated in a pot experiment in complete randomized design layout with three replications. treatments included: control (no waterlogging), waterlogging, tricyclazole plus waterlogging and tricyclazole. tricyclazole (75%) applied at three-leaf stage on canola seedlings. seedlings were exposed to wa...

and any change in climate which alters the length of each phase is likely to alter the root shoot ratio, with effects on forest respiration and photosynthesis. Hence, we need accurate estimates of root and shoot growing periods to predict growth in a changing environment but most models of carbon and nitrogen allocation in trees do not take account of seasonal phases of growth (eg. Thornley, 19...

In order to explore the mechanism of delayed and uneven germination in sharp tooth oak (Quercus aliena var. acuteserrata) (STO), mechanical scarification techniques were used to study STO root and shoot germination and growth. The techniques used were: removing cup scar (RS), removing the pericarp (RP), and cutting off 1/2 (HC) and 2/3 (TC) cotyledons. Germination percentage and root and shoot ...

Amongst a large number of Populus species, micropropagation of P. deltoides has not been possible. The authors now report a reproducible protocol for mass production of cloned plants of 2 important clones of P. deltoides, viz., G3 and G48 through induced shoot bud differentiation in the in vitro cultured segments of leaf, stem and root of adult tree origin. Establishment of experimental plants ...

Pasture productivity in the Mediterranean region depends mainly on soil water deficit. Subterranean clover originates from and is adapted to areas with hot dry summers. The response of Subclover drought was studied greenhouse subjected three soils - levels: 100% (control), 50 25% field capacity (FC). After 70 days deficit treatment, our results showed that increasing levels constraint resulted ...

Vaccinium myrtillus Linn. is an imported fruit tree with high economic value. Currently, in Vietnam there has not been any publication on vitro propagation of the blueberry plant. This study focused V. by nodal culture. The results showed that shoot growth and proliferation were best when nodes cultured WPM medium supplemented 0.5 mg/L zeatin, 30 g/L sucrose, 10 agar, pH 5.8 (shoot height 4.24 ...

Effects of water stress and Fusarium oxysporum f. sp. lycoperseci (Fol) on the growth of tomatoes were studied in a greenhouse experiment. Treatments consisted of five levels of water stress (1, 3, 5, 7 and 9 day irrigation intervals). Infested soil consisting of 400 chlamydospores g1 of Fol and non infested soil were used. Experiments arranged in a completely randomized design with 8 replicati...
