Leaf Appearance Rate of Summer Squash as a Function of Thermal Time [PDF]
HortScience, 1995 Different planting dates were used to study the influence of thermal time on leaf appearance rate of four summer squash (Cucurbita pepo L.) cultivars. During the first year (1991), thermal time or growing degree days (GDD) were calculated using a base temperature of 8C and a ceiling temperature of 32C for several planting dates.

Leaf Appearance Rate and Final Leaf Number of Switchgrass Cultivars [PDF]
Crop Science, 1997 In switchgrass (Panicum virgatum L.), maximum yields occur with late flowering genotypes that have an extended duration of vegetative growth. However, little is known about the developmental basis for a long vegetative growth phase in perennial grasses.

Co-ordination between Leaf Initiation and Leaf Appearance in Field-grown Maize (Zea mays): Genotypic Differences in Response of Rates to Temperature [PDF]
Annals of Botany, 2005 In maize (Zea mays), early flowering date, which is a valuable trait for several cropping systems, is associated with the number of leaves per plant and the leaf appearance rate. Final leaf number depends upon the rate and duration of leaf initiation. The aims of this study were to analyse the genotypic variation in the response to temperature of leaf ...

OENO One, 1995 The rate of leaf appearance was compared in two grapevine (Vitis vinifera L.) varieties (Sangiovese and Cabernet-Sauvignon) and in three different short pruning training systems (traditional cordon, single curtain and vertical cordon pruned).

Agricultural Sciences, 2015 Leaf appearance and leaf elongation rates in rice play an essential role in determining the development of the plants’ architecture which affects their adaptability to varying environments. This study aimed to characterize the rates of leaf appearance and elongation on all leaves of the main culms of rice plants for 11 contrasting varieties and to ...

Effect of light intensity, temperature and daylength on the rate of leaf appearance of maize.
Netherlands Journal of Agricultural Science, 1973 Periodic sowings of maize cv. C.I.V. 2 were made between 1 Feb. and 25 Nov. in glasshouses controlled at 16 or 25 deg C with light intensity about 75% of natural radiation. Some plants were grown in natural daylength, others in 17-h photoperiods. RGR was considerably affected by light intensity and temperature; at 16 deg C it was only about half that ...

Approaches to Modeling Potato Leaf Appearance Rate [PDF]
Agronomy Journal, 2006 Two approaches quantifying potato (Solanum tuberosum L. cv. Kennebec) leaf appearance rates were evaluated: a thermal time approach using the phyllochron, and a nonlinear temperature response approach using a modified β distribution function. Leaf appearance measurements at six temperature treatments (14/10, 17/12, 20/15, 23/18, 28/23, and 34/29°C ...

(80) Calculating Base Temperature and Leaf Appearance Rate for Sweet Viburnum [PDF]
HortScience, 2005 In crop models, it is important to determine the leaf area, because the amount of light interception by leaves influences two very important processes in the plant: photosynthesis and evaporation. Leaf area is dependent on leaf appearance and expansion rates. Leaf appearance rate is driven mainly by temperature. Although the influence of temperature on

Estimating leaf appearance rate and phyllochron in safflower (Carthamus tinctorius L.) [PDF]
, 2005 Safflower may be an interesting option for the flower market, either as fresh or dried cut flower. Estimating the leaf appearance rate and the phyllochron (the time interval between the appearance of successive leaves) is important for calculating the ...

Morphogenetic and structural characteristics of clones of elephant grass managed under intermittent stocking [PDF]
Semina: Ciências Agrárias, 2016 This work was carried out to evaluate the morphogenetic and structural characteristics of basal and aerial tillers of two dwarf elephant grass clones (BRS Kurumi and CNPGL 00-1-3) managed under intermittent stocking in six grazing cycles.
