“…Similar phenomenon was also observed in the common garden samples where leaf samples collected from lowlight condition accumulated more chlorophyll b in both the sun- and shade-grown species. Chlorophyll a is the principal pigment of photosynthesis, whereas chlorophyll b is an accessory pigment collecting energy in order to pass into chlorophyll a (Aronoff, 1950). The shade adapted chloroplast contain more chlorophyll b in order to increase the range of absorbed light wave length (Gommers et al, 2013).…”

Elucidating how the plant species respond to variable light conditions is essential to understand the ecological adaptation to heterogeneous environments. Plant performance and gene regulatory network underpinning the adaptation have been well-documented in sun-grown species. In this study, we surveyed phenotypic and transcriptomic features of four shade-grown and one sun-grown woody species of the family Araliaceae under distinct light conditions. Our phenotypic comparisons demonstrate that the four shade-grown species possess lower light saturation point and higher assimilation ability of the net photosynthetic rate compared to the sun-grown species. In particular, the four shade-grown species maintain similar photosynthesis efficiency in both highlight and lowlight conditions. However, a significantly decreased photosynthesis rate was observed under lowlight condition of the sun-grown species compared to highlight condition. In addition, our leaf anatomical analyses reveal that while all the five species show different anatomical structures under distinct light conditions, the shade-grown species possess lower degree of phenotypic plasticity relative the sun-grown species. Further comparisons of the transcriptome profiling show that all the five species exhibit gene expression divergence among different light conditions. The differentially expressed genes identified in the five species are functionally related to photosynthesis, secondary metabolites and other basic metabolisms. More importantly, differential regulation of the photosynthesis- and photomorphogenesis-related genes are potentially correlated with the phenotypic responses to distinct light conditions of the five species. Our study provides new insights on how the sun- and shade-grown woody species respond to shade and sunlight environments.

“…Tanah yang kering akan menurunkan kemampuan akar dalam menyerap ion-ion yang esensial bagi pertumbuhan tanaman (Lerner, 1999) seperti yang dikemukakan Xu dan Zhou (2005), bahwa cekaman kekeringan menurunkan kadar N total daun. Unsur seperti nitrogen, Mg, dan Fe sangat penting dalam biosintesis klorofil (Aronoff, 1950). Nitrogen dan Mg merupakan unsur pembentuk struktur klorofil sementara Fe dibutuhkan se bagai kofaktor enzim yang penting untuk pembentukan klorofil.…”

“…Nitrogen dan Mg merupakan unsur pembentuk struktur klorofil sementara Fe dibutuhkan se bagai kofaktor enzim yang penting untuk pembentukan klorofil. Defisiensi unsur Fe menyebabkan penurunan aktivitas enzim yang ber peran dalam konversi protoporphyrin menjadi klorofil (Marsh et al, 1963), sedangkan defisiensi Mg dan nitogen menyebabkan penurunan fungsi klorofil (Aronoff, 1950).…”

Physiological response is one of adaptation in plant toward its environment. This is related to plant aBstraKRespon fisiologis merupakan salah satu adaptasi tanaman terhadap lingkungannya. Hal ini sangat terkait dengan produktivitas tanaman karena terjadi perubahan mekanisme fisiologis yang akan menjadi kunci fenotipe dan produktivitas yang dihasilkan. Tujuan penelitian ini yaitu (1) untuk mengetahui respon fisiologis tanaman jagung 'Sweet Boy-02' pada perbedaan intensitas cahaya dan penyiraman serta (2) menentukan intensitas cahaya dan penyiraman yang tepat guna peningkatan produktivitas jagung. Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap dengan 3 faktor intensitas cahaya (63694, 11408 dan 3897 Lux) dan 3 faktor penyiraman (pemberian air sebanyak 2 L; 1,6 L; 1,2 L). Tiap kombinasi perlakuan dibuat tiga ulangan. Penanaman jagung dilakukan di lahan Sawitsari, Yogyakarta. Jagung dipanen saat berumur 75 hari dengan respon fisiologis yang diamati adalah kadar klorofil, kadar prolin, dan panjang akar sedangkan produktivitas jagung diukur dari berat buah tanpa kelobot. Data dianalisis menggunakan Analisis Sidik Ragam Varian (Anava) dilanjutkan dengan uji Duncan's Multiple Range Test (DMRT) pada tingkat signifikansi 5%. Kadar klorofil dan produktivitas tanaman meningkat pada intensitas cahaya L1 (63694 Lux) dan penyiraman W1 (2 L), sedangkan kadar prolin dan panjang akar meningkat pada intensitas cahaya L1 (63694 Lux) dengan penyiraman W2 (1,6 L) dan W3 (1,2 L). Produktivitas jagung paling optimal terdapat pada kombinasi perlakuan L1 (63694 Lux) dengan penyiraman W1 (2 L) ditandai dengan berat tongkol paling besar.Kata Kunci: Adaptasi; Respon fisiologis; Produktivitas; Sweet Boy-02.

“…General reviews of these topics are found in Franck and Loom!s (1949) and Aronoff (1950), but several recent papers emphasized the importance of the breakdown phase. Frank and Kenny (1955) showed that 100% of the chlorophyll and AQ% of the carotenoids were destroyed in 120 hours by leaving normal maize seedlings in the dark at 2,7° 0.…”
