  abstract: Buffelgrass, Pennisetum ciliare (L.) Link (syn Cenchrus
  abstract: ciliaris L.), is a warm season C4 grass with origins in
  abstract: tropical and subtropical regions. Buffelgrass possesses good
  abstract: drought tolerance and excellent forage characteristics, which
  abstract: make it valuable for revegetation of semi-arid regions.
  abstract: However, poor winter survival limits the persistence of
  abstract: buffelgrass to the warmest areas of the southern U.S. This
  abstract: study investigated winter survival in several Pennisetum
  abstract: species. Tiller bases of a buffelgrass x birdwoodgrass
  abstract: (Cenchrus setigerus L.) hybrid with poor winter survival at
  abstract: College Station TX, a moderately winter-hardy buffelgrass
  abstract: genotype (PI 409704) and a winter-hardy species (Pennisetum
  abstract: orientale L. C. Rich. cv Cowboy) were harvested in December,
  abstract: January, March, and April. Across entries the freezing
  abstract: tolerance was greatest in December and declined throughout
  abstract: the winter. The initial freezing tolerance of PI 409704 was
  abstract: similar to Cowboy and significantly greater than the hybrid.
  abstract: Only Cowboy survived the winter. Seedlings of two winter-
  abstract: hardy species, (Cowboy and Pennisetum flaccidum Griseb. cv
  abstract: Carostan); two moderately winter-hardy species, (Pennisetum
  abstract: mezianum Leeke PI 214061 and buffelgrass PI 409704) and
  abstract: Common buffelgrass with poor winter-hardiness were grown at
  abstract: either 20/15 or 10/15 []C with a 9 or 15 hr photoperiod. The
  abstract: photoperiod had no effect on the freezing tolerance. The
  abstract: freezing tolerance increased under 10/5 []C compared to 20/15
  abstract: []C. Carostan had significantly greater freezing tolerance
  abstract: than Common and the rankings of the five genotypes matched
  abstract: the expected field survival. Only Carostan calli exhibited
  abstract: freezing tolerance with a significantly greater freezing
  abstract: tolerance observed at 7 []C compared with 17 []C.
  abstract: Differences in expressed proteins were found between growth
  abstract: at 20/15 and 10/15 []C in Common buffelgrass, PI 214061, and
  abstract: Carostan using SDS-PAGE and 2-D gel electrophoresis. PI
  abstract: 214061 had 11 new proteins not present in Common, mostly in
  abstract: the low to medium molecular weight range. Carostan had 19
  abstract: new proteins not found in either Common or PI 214061. Some
  abstract: new proteins in Carostan were low to medium molecular weight
  abstract: proteins and many were high molecular weight proteins.
  abstract: Callus of Carostan and Common were grown at 17 []C and 7 []C
  abstract: and compared by 2-D electrophoresis also. Comparison of
  abstract: novel cold temperature proteins between Common and Carostan
  abstract: callus and seedlings indicated Carostan had an induction of 2
  abstract: polypeptides, 30 kD/5.7 pI and 24 kD/5.3 pI, in callus which
  abstract: were similar to two polypeptides induced in seedlings.
