The efficacy of biogas was applicable to the isolate used and conditions under which the experiment was conducted. Results from the flame test reveal only treatment C shows signs of flame production that indicates presence of biogas.

Google Scholar Lauridsen E. For the root class, it was found that root class 3 is consistently higher and significantly different compared to root class 1 but not to root class 2 Table 9. On the other hand, height differences as affected by root classes was significant up to the 6th month but became insignificant in the succeeding months. However, for the total tree biomass, provenance from Cotabato was significantly higher as compared with the other two provenances which are insignificant to each other Table 4. Sorry, preview is currently unavailable. The setups were then sealed with a constructed bottle caps tightly and allowed a tape to wound around.

Root classes on the other hand, reported root class 3 as significantly higher with root class 2 and 1. Family mean heritability estimates. Studies with Loblolly pine have shown survival and growth to be positively correlated with seedling diameter South et al. The three factors did not show variations on basal area, and merchantable height. Ashalatha M, Kuber Literaature.

Western Journal of Applied Forestry12 3: This tree is commonly planted as a garden and an avenue tree; growing in villages along agricultural land and on village community lands and wastelands. Saplings and young plants need protection from deer and cattle.

Evidences from the works of Richardsonpoint to the fact that lateral root initiation and growth are influenced by both nutritional and hormonal factors derived from the shoot. Ln present article provides all necessary information regarding its literature. Operational experiences tended to indicate that, other factors being equal seedlings with large stem calipers or diameters outperform those with smaller ones ChavasseCleary et al.

Dbh, basal area, root and total tree biomass revealed significant relationship with root classes Figure 6 while, all parameters measured were significantly related with root biomass Table 6.

Ina and Papa, brother and sister, his loving wife and kids and c above all to most merciful and most beneficent Allah who made this work possible. This tree can be propagated by seedlings, rooted cuttings, and grafting. Total height revealed revieew differences in terms of root classes.

Nursery cultural conditions such as seedling bed density, fertility, moisture and mycorrhizal conditions have been shown to affect stem diameter. Quezon and Cotabato were significantly different literaturs Davao del Sur provenance Table 2.

Methods of measuring RGP have already been standardized in many temperate countries but this has not been done in the tropics including the Philippines Gazal Click here to sign up. All factors pn not show variation on basal area, and merchantable height.

The results of the analysis indicated that the RGP in terms of root class and root biomass of Gmelina tree was positively associated with the other growth traits and characters.
