Effect of urea, (NH4)NO, and NI-14C1 on the growth of wheat cv. Lu-26-S in sandy clay loam was stud¬ied. N fertilizers significantly increased plant height, number of tillers, straw weight and grain yield with marked effects ...

Fifteen plant latices of the families Apocynaceae, Asclepiadaceae and Sapotaceae have been investigated for the presence of acid phosphatase and adenosine triphosphatase enzymes. The latices studied possess both acid ...

In Antirrhinum majus the pal-rec-low-o is a repressed state of the pallida-recurrens allele. In heterozy¬gous condition, especially with pal-tub pal-tub tester, its mutation frequency increases from few tiny spots to very ...

Regenerating seedlings from 60 mature stands on Juniper track in Baluchistan ranged from zero to 219 ha-' with a mean of 52 ha-'. Seedling density and basal area (P < .001) and tree basal area and seedling density (P < ...

Herbaceous communities that emerge on the Pakistan sea coast during monsoon have high percentage of therophytes followed by chamaephytes. Besides, dominant component of grasses, legumes were invariably present in all the ...

Seasonal histochemical localization of starch, lipids, proteins, tannins and crystals in fusiform and ray initials and their derivatives of Holoptelea integrifolia and Mangifera indica was carried out. The seasonal changes ...

Six induced mutants of the costata type are described. I was found that three mutants were allelic. Linkage analysis confirmed the localization of the costata gene lum in chromosome 4.

Protoplasts from leaves, roots excised from young seedlings and calli induced from roots of seeds have been isolated with a digestion mixture containing 2.5% Macerozyme, 2.5% cellulase Onozuka-R40 and i% hemicellulase in ...

Hairs of 66 species of genus dampiera R. Br, from the outside of corolla were examined. Three main types of hairs are recognized in this genus. The hairs shape and their nature can be used as a most important taxonomic ...

A Monte Carlo algorithm is proposed to assi on a new or unclassified operational taxonomic unit (O.T.U.), with variable characters, to the group it is closest to. The method involves a bootstrap resampling plan. The algorithm ...
