Pot culture experiments were conducted with the seedings of Pinus Garibaea to evaluate the influence of deficiencies of macro-elements on dry matter and holocellulose production and mineral uptake. Deficiencies of all the macro-elements have reduced dry matter production. Lowest dry matter was produced in potassium deficiency treatment. Plant analysis results. have indicated that different deficiency treatments influence mineral uptakte differently. Holocellulose productions has shOwn direct linear relation to shoot dry weight.

Pot culture experiment was conducted with the seedlings of Pinus caribaea to evaluate the influence of different photoperiodic treatments on fresh and dry weights and holocellulose production and mineral uptake. Long day and interrupted day treatments have produced significantly better fresh and dry weights than normal day and short day treatments. Highest fresh and dry weights of shoot were produced in interrupted day treatment and of ischolar_main in long day treatment. Holocellulose production has shown direct linear relation to shoot dry weight. Plant analysis results have indicated that different photoperiodic treatments also influence mineral uptake, particularly of nitrogen, phosphorus and potassium.- Photoperiodic Response of Growth of Pinus caribaea Seedlings: I Effect on Stem Height and Diameter and Tracheid Characters

Pot culture experiment was conducted with the seedlings of Pinus Caribaea to evaluate the effect of different photoperiodic treatments on growth and tracheid characters. The study haa revealed that both growth and tracheid characters are responsive to day length variations. The results indicate significant variations in stem height and diameter and tracheid characters. Long day treatment has significantly increased stem height, tracheid length, tracheid diameter and tracheid lumen diameter. Significant increase in stem diameter has been observed under interrupted day treatment.- Studies on the Effect of Growth Regulators on Growth and Tracheid Characters of Pinus caribaea Seedlings

Pot culture experiments were conducted with the seedlings of Pinus caribaea. Morelet var.hondurensis is to study the effect of different growth regulators on height aad diameter growth and tracheid characters. Gibberellic acid, Indole acetic acid and Indole butyric acid were given at 10, 100 and 1000 ppm concentrations. Studies reveal that except IAA 1000 ppm all the other growth regulator treatments have enhanced the height growth. Gibberellic acid at 1000 ppm has given best height growth, whereas, the best diameter increment has been obtained under IAA 10 ppm. Tracheid length variations among different treatments are highly significant. The longest tracheids were formed under GA 1000 ppm. No significant variations have been observed for tracheid and lumen diameter, but wall thickness results have shown significant differences among different treatments in the middle region.- Effect of Growth Regulators on Fresh and Dry Matter and Holocellulose Production and Mineral Uptake by Pinus caribaea Seedlings

Pot culture experiment was conducted with the seedlings of Pinus caribaea Morelet var. hondurensis to study the effect of Gibberllic acid, Indole acetic acid and Indole butyric acid on fresh and dry weight and holocellulose production and mineral uptake. IAA 10 ppm. concentration has given maximum fresh and dry weight and holocellulose production. This treatment has also influenced higher uptake of nitrogen, potassium., phosphorus and calcium.- Effect of Defoliation on Growth and Tracheid Characters of Pinus caribaea Seedlings

Experiments were conducted with the seedlings of Pinus caribaea to study the effect of defoliation on growth and tracheid characters. In general, the defoliation of upper half of the stem brings about more retardation of radial growth as well as height growth than the defoliation of lower half of the stem. This is true also for the tracheid length and tracheid wall thickness. No distinction in the effect of defoliation of upper half or lower half have been obtained in the case of tracheid or lumen diameter. In the case of dry matter production, it is indicated that higher degree of defoliation retard the production more than lower degree of defoliation Here also the defoliation of lower portion is less effective in retardation of dry matter than the defoliation of upper half. Mineral and holocellulose contents have CoULwed similar trend as that followed by dry matter.- Effect of Debudding on Growth and Tracheid Characters of Pinus caribaea Seedlings
