Isotopic composition of plant carbon correlates with water-use efficiency of wheat genotypes.
The extent and significance of seed size variation in New Zealand wheats ( Triticum aestivum.).
(1991b) exemplifies these effects.
Paris, John Libbey Eurotext.The example given here is for a plant with eight leaves on the main stem.Roots and leaves that develop in the fall are often killed off during the overwintering period.Field Crops Res., 18: 127-140.In the early stages, the description of each new leaf is related to the previous leaf that was produced.The use of thermal time rather than calendar time takes this variability into consideration and provides an explanation for differences in crop maturity when observations from different years are compared.Table.8 Some yield components and duration of GS2 at various mean seasonal growing temperatures Mean new york escort sites seasonal temperature (C) Kernel numbera (grains/m2) x 102 Spikes/ma Duration of GS2 (days).2.0a 349.2a.8.7.1b 292.9b.9.9.6c 163.2c.4.5.0c 145.6c.5.10.4 Heading three-quarters complete.Once the photoperiod insensitive period ends, floral induction starts and the reproductive stage begins (double ridge).Delaying N fertilization through DC 30 not only increases grain yield but also decreases lodging and lowers fertilizer losses thus increasing N recovery (Brooking and Kirby, 1981; Wuest and Cassman, 1992a, 1992b).
Influence of seed size and test weight on several agronomic traits of barley and hard red spring wheat.
The increase in potential grain yield has come essentially from an increase in harvest index and particularly from an increase in grain number per unit area (see above) rather than an increase in kernel weight.
The embryo of the mature wheat kernel has already undergone the first stages of plant development before the kernel is separated from the parent plant.
Temperature effects at three developmental stages on the yield of the wheat ear.
Plant Physiol., 13: 523-532.
Angus,.F., Cunningham,.B., Moncur,.W.Increases in the nitrogen of the canopy increase Amax and RUE.Critical growth stages Successful adaptation of a crop species is dependent upon the programming of critical growth stages so that the plant can capitalize online dating for older adults uk on favorable weather periods during the growing season.The sex addicts online dating salinity resistance per se found by Acevedo.Floret initiation starts in the lower central region and progresses toward the base and tip of the head.The roots, leaves, tillers, and spikelets on the head of the wheat plant develop from primodia at nodes.Field Crops Res., 35: 101-111.Prospects for genetically increasing the photosynthetic capacity of crops.
