For instance, survival of 2-y-old greenlip abalone (Haliotis laevigate
) fed the commercial or Ulva lactuca at 26[degrees]C was all over 90%, but survival (65%) of 3-y-old abalone fed the commercial diet was lower than that (90.2%) of abalone fed the U.
Description:Trilete spore, amb subcircular, tetrad mark clear, exine thin and folded, Laevigate to infrapunctate, 1m thick.
Lete mark , extendedup to equator,exine laevigate to infrapunctate, 1.5 m thick.
Spores without ornamentation include: laevigate, or smooth and with microomamentation but lacking macroornamentation; and psilate, or smooth and without microornamentation or macroornamentation.
Of the 52 collections examined, 21 had echinate macroomamentation; 19, aculeate; 6, cristate; 5, psilate; and 1, laevigate (Appendix I).
2.2 Description: Trilete, amb broadly triangular, angles rounded, sides straight to slightly convex, lete distinct, arms of lete extending upto the angles, labrum distinct, exine laevigate to infrapunctate, 1.5 m thick
Described here are three genera of azonotriletes, which were either laevigate (Leiotriletes), granulate or punctate (Granulatisporites and Punctatisporites).
Description: Miospore, trilete, amb circular to sub- circular, highly variable due to folding, Y-mark distinct, rays extending up to 2/3rd of the radius, exine variously folded, laevigate, about 1m thick.
Description: Miospore, monolete, amb circular, lete well developed, labra thick, raised, contact area well developed, exine thin, laevigate to infrapunctate, up to 2m thick.
Description: Pollen grain, monosaccate, bilaterally symmetrical, overall amb oval or oblong oval, corpus circular in polar view or sub circular or rhomboidal, the proximal face associated with a sharp, slightly curved (angular) monolete mark with thin labra, exine of corpus laevigate
to infra punctate, on the distal side the attachment zone of the saccus is indicated by two folds which are faintly discernable in the figured specimen due to poor preservation, exoexine of saccus intrareticulate up to 2 m thick, muri 1.5-2 m wide, lacuni 3 x 5 m wide, saccus distally inclined, surrounding the central body equatorially, the lateral continuation of the saccus is usually broad, marginal limbus poorly developed.
Exine with sharply defined, laevigate exoexinus ribs, individual ribs continuous and looped so that those near to periphery pass without interruption from the proximal to the distal face.
Description: Pollen grain, polyplicate, overall amb oval or rounded oval, exine clearly differentiated into exoexine and intexine, exoexine infrapunctate to granulate or intrabaculate, 3-5m thick at equator appearing as a rim, intexine 1.0-1.5 m thick, laevigate, sulcus smooth running approximately parallel to the long axis of the grain.
