Ļoti ilgi meklēju informāciju un nekā nevaru atrast. Tāpēc arī izlemju uzdot šo jautājumu speciālistiem biologiem. Vai tā ir patiesība, ka hlorofilu koncentrācija priežu skujās mainās atkarībā no sezonas? Ja tas tiešam tā ir, tad kāds (kādās robežās) parasti ir a un b hlorofilu daudzums skujās no priedei, kura aug ekoloģiski tīrā teritorijā (mērvienība: hlorofilu a un b summas daudzums (mg) uz 1 g SVAIGO (ne izžāvēto!) skuju) ziemā un, piemēram, vasarā? Liels paldies

    Hlorofila daudzums priežu skujās noteikti mainās atkarībā no sezonas. Hlorofils nav konstants lielums: tas noārdās un sintezējas atkal no jauna. Hlorofila daudzumu ietekmē gan augu suga, gan šķirne, gan vides apstākļi. Tā kopējais daudzums vaskulārajos augos ~0.1-0.7% svaigās masas. Priežu skujās hla:hlb~2.5-3. Lai veicas eksperimentos

    To jau parasti neviens no galvas nezin, ja nav tādas analīzes veicis. To visu var sameklēt zinātniskajā literatūrā caur Google un Scholar Google. Atradu Jums vienu avotu par tēmu:http://epsilon.slu.se/studia/SFS100.pdf
