RATE AND DURATION OF DRY MATTER ACCUMULATION IN RELATION TO KERNEL SHRIVELLING IN TRITICALE

Canadian Journal of Plant Science, 1978
Several lines of triticale (X Triticosecale Wittmack), varying in their degree of shrivelling, were grown in the field. The ratio of the final seed volume to the maximum volume attained during development was used as a measure of shrivelling. Shrivelling was correlated with total dry matter in the seed, but not with its maximum size. When rates of dry

Effects of Seeding Rate on Growth Duration and Accumulation and Partitioning of Dry matter in Oats

Journal of Agronomy and Crop Science, 1994
AbstractCrop management influences considerably the three components of grain yield, growth duration, growth rate, and harvest index (HI). Effects of seeding rate on these yield components in oats (Avena sativa L.) was assessed in field experiments at the Viikki Experimental Farm, University of Helsinki, Finland (60°13′N) in 1991 and 1992.

Critical period for seed number determination in soybean as determined by crop growth rate, duration, and dry matter accumulation

Field Crops Research, 2021
Abstract Seed number (SN) is positively associated with aboveground dry matter (ADM) accumulation in most crop species. In soybean, there are discrepancies among studies relative to the start and end of the critical period for seed number determination. The objective of this study was to more precisely identify those two stages. To do so, we followed

EFFECTS OF NITROGEN RATES ON DRY MATTER AND NITROGEN ACCUMULATION IN CITRUS FRUITS AND FRUIT YIELD

Journal of Plant Nutrition, 2001
Fruit growth patterns and nitrogen (N) accumulation in fruit over the growth period were studied on ‘Valencia’, ‘Parson Brown’, ‘Hamlin’, and ‘Sunburst’ cultivars which received either 168, 224, or 280 kgNha−1yr−1 as broadcast applications of N:P:K dry soluble granular fertilizer. Over a 4-year period, fruit yields of all cultivars did not respond to N

Factors Limiting the Rate of Dry Matter Accumulation in the Grain of Wheat Grown at High Temperature

Australian Journal of Plant Physiology, 1980
Increasing temperatures from 21/16°C to 30/25°C, during the period of development from anthesis to maturity, substantially reduced grain dry weight in wheat. Although this was associated with a shorter duration of grain development, the failure to obtain any compensating increase in the rate of dry matter accumulation, as occurs in the lower ...

Effects of Calcium Application Rate on Dry Matter Accumulation and Yield of Peanut

2018
The effects of calcium application rate on dry matter accumulation and yield of peanut were studied under high-yielding field condition. The variety used for the study was Tang A8252 (Spanish peanut). The results showed that number of full fruit, dry weight per plant, kernel yield, and pod yield all increased with calcium application increased, and ...

Comparative growth, dry matter accumulation and photosynthetic rate of seven species of Eucalypt in response to phosphorus supply

Journal of Forestry Research, 2014
Plantations of eucalypts as short-rotation tree crops are rapidly expanding in tropical and sub-tropical regions, including southern China, where the soils are acidic and available phosphorus (P) is limited. We investigated seedling growth, dry matter accumulation, and the dynamics of photosynthetic rate and chlorophyll content of seven Eucalyptus ...

Broccoli growth in response to increasing rates of pre-plant nitrogen. II. Dry matter and nitrogen accumulation

Canadian Journal of Plant Science, 2009
An understanding of plant nitrogen accumulation and soil nitrogen dynamics is needed to develop management practices that balance nitrogen requirements of vegetable crops with environmental protection. Field trials were conducted in 2001 and 2002 to determine the interaction of increasing rates of pre-plant nitrogen fertilizer with broccoli tissue ...

Effects of reduced nitrogen application rate on drip‐irrigated cotton dry matter accumulation and yield under different phosphorus and potassium managements

Agronomy Journal, 2021
AbstractTo elucidate effects of reduced N application rate on dry matter accumulation and yield of drip‐irrigated cotton (Gossypium hirsutum L.) under different phosphorus and potassium managements (PK‐Ms), field studies with four reduced N application rates and four PK‐Ms were conducted in 2018 and 2019. Results show that after early peak boll‐forming

Rate of Dry Matter Accumulation in Soybean Seeds with Varying Source‐Sink Ratios¹

Agronomy Journal, 1976
AbstractThe rate of accumulation of dry weight in the seed is one important process in yield production by grain crops. Information on factors influencing the seed growth rate are needed to help identify yield limiting processes. This study was undertaken to determine the effect of varying source‐sink ratios on the rate of dry matter accumulation in ...
