Estimating leaf appearance rate and phyllochron in safflower (Carthamus tinctorius L.) [PDF]

open access: yesCiência Rural, 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 ...

Modeling leaf appearance rate for Canada Western Red Spring wheat cultivars [PDF]

open access: yesCanadian Journal of Plant Science, 2010
The rate of leaf appearance [LAR (d-1)] was observed for two older (Marquis and Neepawa) and two newer (AC Barrie and AC Elsa) Canada Western Red Spring (CWRS) wheat (Triticum aestivum L.) cultivars grown in a semiarid environment on the Canadian prairies for four years.

Simulating leaf appearance in a maize variety

open access: yesBioscience Journal, 2010
The calculation of leaf appearance rate (LAR) is an important part of many crop simulation models. The objective of this study was to evaluate and compare a linear model (the Phyllochron model) with a non-linear model (the Wang and Engel, WE, model) for ...

Temperature response function for leaf appearance rate in wheat and corn

open access: yesCanadian Journal of Plant Science, 1999
The ability to predict leaf appearance would enhance our capability of modeling plant development and the rate of leaf area expansion. Many crop models use the constant thermal time for successive leaf tip appearance (which is often termed a phyllochron) as one model parameter to predict total number of leaves and date of anthesis.

Wheat Developmental Traits as Affected by the Interaction between Eps-7D and Temperature under Contrasting Photoperiods with Insensitive Ppd-D1 Background

open access: yesPlants, 2021
Earliness per se (Eps) genes are important to fine tune adaptation, and studying their probable pleiotropic effect on wheat yield traits is worthwhile. In addition, it has been shown that some Eps genes interact with temperature and therefore determining

Relationship between Vessel Formation and Seasonal Changes in Leaf Area of Evergreen and Deciduous Species with Different Vessel Arrangements

open access: yesPlants, 2021
To discuss the diversity of morphological traits and life strategies of trees, the functional relationship between leaf expansion and vessel formation must be clarified.

Overexpression of PtoCYCD3;3 Promotes Growth and Causes Leaf Wrinkle and Branch Appearance in Populus

open access: yesInternational Journal of Molecular Sciences, 2021
D-type cyclin (cyclin D, CYCD), combined with cyclin-dependent kinases (CDKs), participates in the regulation of cell cycle G1/S transition and plays an important role in cell division and proliferation.

Phenology and Floret Development as Affected by the Interaction between Eps-7D and Ppd-D1

open access: yesPlants, 2021
Earliness per se (Eps) genes may play a critical role in further improving wheat adaptation and fine-tuning wheat development to cope with climate change.

تأثیر سطوح شوری آب آبیاری با NaCl بر فیلوکرون و سرعت ظهور برگ ارقام جو [PDF]

open access: yesتنش های محیطی در علوم زراعی, 2016
شوری منابع آب‌وخاک از مهم‌ترین مشکلات کشاورزی در مناطق خشک و نیمه‌خشک ایران است. برای بررسی تأثیر شوری آب آبیاری بر فیلوکرون و سرعت ظهور برگ ارقام جو، آزمایشی به‌صورت فاکتوریل در قالب طرح پایه بلوک‌های کامل تصادفی با سه تکرار در گلخانه دانشکده کشاورزی ...
