Arjan:
I am sending you a WP4.2 file named SPECIES.DOC, that attempts to give
definitions, a bit at a time under each new section of the species file. I
don't even know which crop this came from. This file is attached. An
ASCII file named SPECIES.ASC is also attached, but it may cause wrap, if
greater than 80-column
I also attaching a recent peanut ECO file and CUL file which have the
definitions. I don't know what your files do not have the short definitions.
Good luck on this.

PARMAX AND PHTMAX - define asymptotic response of daily canopy assimilation to
daily photosynthetic photon flux, where PHTMAX is the asymptote (g CH2O/m2/day)
and PARMAX is PPFD at which ????? Check with JWJ. Increase PHTMAX to increase
dry matter growth for daily option only.
KCAN - Light extinction coefficient for daily canopy option, dimensionless. Also
impacts radiation extinction for transpiration (KCAN + 0.15).
CCMP, CCMAX, & CCEFF - All normalized, define the response of daily canopy
assimilation to CO2. CCMP is the canopy compensation point, CCEFF is the initial
slope and CCMAX is a normalized point that indicates that canopy rate can be 2.09
times greater at saturating CO2 than at 350 ppm CO2. Check with JWJ.
FNPGN(4) and TYPPGN - This is a two-sided generic curve, in this case, using only
the two leftmost points to describe both canopy and leaf photosynthesis response
to leaf N concentration. QDR defines a quadratic curve as photosynthesis
increases from zero at the minimum leaf N concentration to its maximum at the
maximum leaf N concentration. Same leaf-derived function is used for leaf and
canopy options; however, subroutine PHOTO modifies it for DAILY option with a
square root change.
FNPGT(4),TYPPGT - Another two-sided generic curve, in this case, LIN means
linear 4-point lookup, that describes daily canopy assimilation in response to
average (?????) daytime temperature.
Remainder of photosynthetic parameters apply only to LEAF-level option:
XLMAXT (6 VALUES) and YLMAXT (6 VALUES) - This is a 6-point lookup function, that
describes relative rate of photosynthetic electron-transport (YLMAXT) in response
to temperature (XLMAXT). Used only for Leaf option and affects computed light-
saturated leaf photosynthesis.
FNPGL(4),TYPPGL - Describes relative effect of minimum night temperature (TMIN)
on next day's single leaf light-saturated photosynthesis rate. Use only the two
leftmost values, assuming QDR quadratic/parabolic response from 0.0 to 1.0 (no
effect) on leaf photosynthesis.
PGEFF - Quantum efficiency of leaf photosynthesis, defined at 350 ppm CO2, 21%
oxygen, and 30 C. Set from published values in literature, Ehlringer and
Bjorkman.
SCV - Scattering of photosynthetic photon flux by single leaves (transmittance
and reflectance.
KDIF - Diffuse beam extinction coefficient.
LFANGB - Leaf angle distribution (type), 2 = spherical, from Campbell and Norman,
1989. Plant canopies: their growth, form and function. See meaning of other
"numbers" that can be used.
SLWREF - Specific leaf weight at which LFMAX is defined.
SLWSLO - Rate of change in SLW with cumulative LAI depth.
NSLOPE - Rate of change in leaf N concentration with cumulative LAI depth
LNREF - Leaf N concentration at which LFMAX is defined, it really should be at
the maximum N concentration, but is a bit belong.
PGREF - Used only for the daily canopy assimilation option. Allows cultivar
variation in LFMAX to change daily canopy assimilation. PGREF should really be
in the middle of, or represent the standard cultivars used, such as Bragg. Not
used for the leaf-level, hedgerow photosynthesis option.
XPGSLW(1-10) & YPGSLW(1-10) - Relative change in DAILY canopy assimilation with
change in average canopy SLW, normalized to 1.00 at SLWREF, which is where leaf
photosynthesis is defined.

R30C2 - Constant that describes maintenance respiration as a function of
RNO3C - g of glucose required for growth respiration and synthesis of a gram of
protein with nitrate as the N source.
RNH4C - g of glucose required for growth respiration and synthesis of a gram of
protein with ammonium as the N source. Use same as nitrate because most N is
converted to NO3 anyway, and there is uncertain added C costs for organic acid
synthesis for cation balance for NH4-fed plants.
RPRO - Cost to re-synthesize protein from reduced-N amino acids after breakdown
of protein. Is this correct?
RFIXN - g of glucose required for growth respiration and synthesis of a gram of
protein with N-fixation (hydrogenase-negative) as the N source.

WTFSD - Fraction of initial seed dry weight that is plant mass at emergence.

peak early vegetative phase, under optimum temperature, water, and light. Actual
SIZREF - Supposedly leaf area per trifoliate (tetrafoliate) leaf for the leaf at
the 5th node position. Actually, can modify the rate of leaf area expansion for
the first VSSINK leaf nodes, to limit rate of leaf area expansion until VSSINK.

is totally source-driven.
EVMODC - A modifier of rate of vegetative node appearance for the first few
nodes, primarily used for peanut. Not particularly important.
SLAMAX,SLAMIN,SLAPAR - These three describe SLA response of new leaf area to
solar irradiance: SLAMAX is the maximum (thinnest) leaves can be under low
light, whereas SLAMIN is the minimum (thickest) leaves can be under high light,
and SLAPAR describes the curvature. The function and curvature come from Cox et
al. for peanut response to light in a phytotron.

soil water affects peanut fruiting.
XFRMAX - Degree of increase in partitioning to pods, rather than vegetative
growth, when water deficit occurs during pod growth.
SHLAG - Slow growth phase (lag) in shell growth (used primarily for peanut).
FNPDT(1-4),TYPPDT - Relative temperature effect (2-sided parabolic shape, two

sensitivity of pod set to cool temperature. Will use ecotype trait in next

from Egli and Wardlaw, above end confirmed in Florida SPAR experiments.
YXFTEM(1-6) vs. XXFTEM(1-6) - Describes a 6-point curve of relative partitioning

below 20, I'm not sure we intended the values as ended up here. Probably one of
the reasons for low yields in cool locations.
YSWFAC(1-4) vs. XSWFAC(1-4) - Describes soil water deficit effect on pod
addition, in addition to effects on assimilate supply. I'm not sure this
function is needed or advisable.
YSWBAR(1-5) vs. XSWBAR(1-5) - Relative response of peanut fruit pegging in
response to soil water available only in the top SWBAR of soil. Function should
