Comparision of in
vivo and in vitro translation of
the anemia phyllitidis poly (A)+ RNA during spermatogenesis ABSTRACT: Ribonucleic acid was extracted from
10 days old reproductive prothalli of the fern anemia phyllitidis . polyadenyiated RNA was isolated by using poly (U)- sepharose chromatography and its composition was studied by translating the poly (A)+ RNA in vitro in rabbit reticulocyte lysate. Electrophoretic analysis of the in vitro translation products and of proteins synthesized in vitro gave many common components , but there were also distinct quantitative and qualitative differences in the protein composition of the products of the two fractions . the in vitro synthesized proteins formed a heterogenous population , ranging in molecular weight from 10,000 to
72,000 , while those from in vitro ranged from 10,000 to over 120,000 daltons.

Effect of abscisic
acid on the exudation process in excised roots of
maize, millet and sorghum. ABSTRACT: The effect of abscisic acid (ABA) on the
exudation process in excised roots of maize 9zea mays L.) pearl millet ( pennisetum typhoideum rich ) and sorghum ( sorghum vulgae pers ) was investigated . ABA supplied to the growth as well as the bathing media stimulated volume flow (fv) and to a lesser extent the potassium flux (JK) from all three species. The major
factor causing stimulation was an ABA
induced increase in the hydraulic conductivity of the root (Lp).

Salt tolerance studies on IPIL IPIL (leucaena leucocephela L.) CV. K-8M.L.K. NIAZI , M.I. HAQ AND KAUSAR A. MALIK
Salt tolerance studies on IPIL IPIL (leucaena leucocephela L.) CV. K-8 ABSTRACT: Ipil ipil (leucaena leucocephela L.) CV. K-8 has been studied for its salt tolerance in pots containing gravel soaked in nutrient solution maintained at electrical conductivity (EC) of 3,5, 10 ,15 and 20 mScm-1. Increase in salt contents adversely affected germination and plant growth . fifty percent reduction in plant growth occurred at EC of 12.4 mScm-1.

Chemical
composition of wood of some eucalyptus species growing in Pakistan ABSTRACT: Holocellulose , alphacellulose and
lignin, three major cell wall components, of severe eucalyptus species viz, E. camaldulensis ehnh , E. clurtodora hook, E. maculate hook, E.mannifera mudia. E. melanophloia, F. muell , E. microtheca , F. muell, and E. tereticornis Sm, were investigated from extractive-five wood of trunks and branches . amount of holocellulose ranged between 67.80-
77.93% in trunkwood and 67.22-
76.19% in branch-wood , alphacellulose 40.9-47.1% im trunkwood and 36.25-43.84% in
branch wood and lignin 22.02-32.28 % in trunkwood and 23.45-32.77 % in branchwood. There was not much variation in the amount of these polysaccharides among the species investigated.

Induced somatic mutation in mango , mangifera indica L. cv. LangraS.H.SIDDIQUI
Induced somatic mutation in mango , mangifera indica L. cv. Langra ABSTRACT: Dormant buds of mango (mangifera indica L. cv. Langra ) exposed to acute gamma-irradiation dosages of 1.0, 2.0,
3.0,4.0, 5.0 and 6.0 kiloroentgens (KR), were grafted on to one-year-old seedling stock. Dosages of 2.0 and 3.0
KR were found satisfactory for the purpose , as measued by bud lethality and scion growth. A bud graft from
3.0 KR bore fruits of excellent
quantity . compared with the control,
the fruits were heavier , largere and had more creamish- yellow pulp. None of the other morphological changes expressed by the mutant fruits , observed over three fruiting seasons, were disadvantageous . the tree habit is being further
investigated before the mutant can be considered for release as an iproved cultivar.
