Selection of Pinus pinea L. plus tree candidates for cone production [PDF]
Annals of Forest Science, 2010 Multivariate statistical analysis was used to define different developmental stages for stone pine (Pinus pinea L.) considering tree size and cone production, without site-specific information. * This was achieved in two steps. First, trees from permanent plots were classified using cluster analysis in five different stages.

Genetic Evaluation by Microsatellite Loci of Pinus sylvestris L. Plus Trees
Лесной журнал, 2023 In this study, a comparative analysis was performed to estimate the genetic diversity levels of Pinus sylvestris L. in 49 seed orchards of I generation and progeny test plantings using 4-nucleus microsatellite loci.

Finite Sequentiality of Unambiguous Max-Plus Tree Automata [PDF]
Theory of Computing Systems, 2021 AbstractWe show the decidability of the finite sequentiality problem for unambiguous max-plus tree automata. A max-plus tree automaton is called unambiguous if there is at most one accepting run on every tree. The finite sequentiality problem asks whether for a given max-plus tree automaton, there exist finitely many deterministic max-plus tree ...

GENETIC AND BREEDING ASSESSMENT OF SCOTS PINE PLUS TREES IN KARELIA
Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2020 Growth and survival of 123 grafted and half-sib Scots pine (Pinus sylvestris L.) progenies have been investigated in a 1st generation seed orchard and progeny tests of variousages.

Oakwood and plus trees common oakfruiting [PDF]
Forestry Engineering Journal, 2017 The objects of research were the groves of the Central Chernozem and plus trees selected in them. Oakwood in the re-gion has long been intensively exploited, their area reduced by 2-3 times, and the gene pool is severely malnourished. Restor-ing oak occurs very difficult with large omissions and economic costs.

Finite Sequentiality of Finitely Ambiguous Max-Plus Tree Automata [PDF]
Theory of Computing Systems, 2021 AbstractWe show that the finite sequentiality problem is decidable for finitely ambiguous max-plus tree automata. A max-plus tree automaton is a weighted tree automaton over the max-plus semiring. A max-plus tree automaton is called finitely ambiguous if the number of accepting runs on every tree is bounded by a global constant.

Frontiers in Plant Science, 2022 Grafting induces precocity and maintains clonal integrity in fruit tree crops. However, the complex rootstock × scion interaction often precludes understanding how the tree phenotype is shaped, limiting the potential to select optimum rootstocks ...

Unambiguous Separators for Tropical Tree Automata [PDF]
, 2019 In this paper we show that given a max-plus automaton (over trees, and with real weights) computing a function f and a min-plus automaton (similar) computing a function g such that f ?
