Abstract

During plant development, leaves undergo various ontogenetic changes, including differences in size, shape, and geometric dimensions. An in-depth study of morphological traits showed differences in species and populations according to adaptive traits. The P. edulis species of the Passiflora genus undergoes heteroblastic-significant changes as it grows and develops, showing a morphological distinction between young and mature vegetative phases. Morphological polymorphism of the leaves of Passiflora edulis L., one of the most promising species introduced to Azerbaijan and grown under ex situ and in situ conditions, was studied and analyzed mathematically. The leaf area was 145.9 cm2 under ex situ conditions and amounted to 115.5 cm2 under in situ conditions; The perimeter of the leaf under ex situ conditions was 378.49 cm, while in plants grown under in situ conditions this parameter was 366.5 cm. The morphological characteristics of the leaves were found to be higher in the samples grown under ex situ conditions compared to the in situ conditions. However, in addition to the leaf perimeter, diversity observed in other morphological traits and the coefficient of variation were higher in plants developed under in situ conditions compared to those grown ex situ. This is attributed to the greater stability of abiotic factors under ex situ conditions compared to in situ conditions. The high variance indicates the high adaptability of the P. edulis species.

Abşeron'a getirilen Passiflora edulis L. Türünün Yapraklarının Morfometrik Parametrelerinin Değişimi

Abstract

Bitki gelişimi sırasında, yapraklar boyut, şekil ve geometrik boyutlardaki farklılıklar dahil olmak üzere çeşitli ontogenetik değişikliklere uğramışdır. Morfolojik özelliklerin derinlemesine bir incelemesi uyarlanabilir özelliklere göre türlerde ve popülasyonlarda farklılıklar gösterdi. Passiflora cinsinin P. edulis türü büyüdükçe ve geliştikçe heteroblastik-önemli değişikliklere uğrar ve genç olgun vejetatif fazlar arasında morfolojik bir ayrım gösterir. Azerbaycanda tanıtılan en umut verici türlerden biri olan ex situ ve in situ koşullarda yetiştirilen Passiflora edulis L.'nin yapraklarının morfolojik polimorfizmi matematiksel olarak incelenmiş ve analiz edilmiştir. Yaprak alanı ex situ koşullar altında 145.9 cm2 ve in situ koşullar altında 115,5 cm2'ye ulaştı; Ex situ koşullar altında yaprağın çevresi 378.49 cm iken, in situ koşullar altında yetiştirilen bitkilerde bu parametre 366.5 cm idi. Ex situ koşullarda yetiştirilen örneklerde yaprakların morfolojik özellikleri in situ koşullara göre daha yüksek bulunmuştur. Ancak, in situ koşullarda geliştirilen bitkilerde yaprak çevresine ek olarak diğer morfolojik özelliklerde gözlenen çeşitlilik ve varyasyon katsayısı ex situ yetiştirilenlere göre daha yüksek bulunmuştur. Bu in situ koşullara kıyasla ex situ koşullar altında abiyotik faktörlerin daha yüksek stabilitesine atfedilir. Yüksek varyans P. edulis türlerinin yüksek uyarlanabilirliğini göstermişdir.
