stress spārni augļu muša Bioloģija asimetrijas attīstības ātrums

description

Dabiskās variācijas, ārējās vides apstākļi un attīstības ātrums var veicināt stresu. Darba mērķi bija izpētīt augļu mušu attīstības ātruma variāciju, sadalīt tās trīs attīstības ātruma grupās un izpētīt augļu mušu spārnu laukuma, formas un dzīslu garuma attiecības asimetrijas trijās attīstības ātruma grupās. Rezultātā pirmās augļu mušas izkūņojās 10. dienā, bet pēdējās – 16. dienā. Savukārt statistiski būtiska atšķirības starp augļu mušu attīstības ātruma grupām uzrādījās tikai spārnu laukuma asimetrijas mērījumiem, salīdzinot ātrās un lēnās un ātrās un vidējās attīstības ātruma grupas. No iegūtajiem rezultātiem var secināt, ka, pirmkārt, attīstības ātrums var būt būtiski ilgāks nekā līdz šim uzskatīts, un ka, otrkārt, augļu mušām no ātrās attīstības ātruma grupas ir lielāks stress.
