Aloe vera (S´abila) is used in folk

Aloe vera (S´abila) is used in folklore medicine and commercial cosmetology products in many countries. Little is known about the
plant’s physiological, growth, and yield responses under different irrigation regimes. The plant has a crassulacean acid metabolism
(CAM) that allows water conservation within the tissue, and therefore, resistance to high water stress. A. vera plants were submitted
to different irrigation regimes in a greenhouse experiment to evaluate the response of the physiologic processes such as stomatal
resistance and transpiration as well as leaf growth and yield. The experiment consisted of three irrigation regimes under a completely
randomized design. No initial effect on stomatal resistance or transpiration was exhibited, but as time elapsed changes in these
variables were noted.We suggest that the high water content in the parenchyma maintains stomatal opening despite water stress. In
a subsequent period, the leaves that were submitted to water stress at the beginning, showed stomatal opening reduction related to
low soil water potential. The low soil water potential reduced leaf weight, plant growth rate, and leaf number, mainly in leaf growth
during the experiment confirming the sensitivity of new leaves to water stress. The results suggest that the low leaf temperature
increases stomatal resistance, decreases plant and leaf growth rates. This behavior is opposite to other CAM species in semiarid
condition.

Aloe vera (S´abila) digunakan dalam pengobatan cerita rakyat dan tata rias komersial produk di banyak negara. Sedikit yang diketahui tentangtanaman fisiologis, pertumbuhan, dan tanggapan hasil di bawah rezim irigasi yang berbeda. Tanaman ini memiliki metabolisme asam crassulacean(CAM) yang memungkinkan konservasi air dalam jaringan, dan oleh karena itu, perlawanan terhadap tekanan air tinggi. A. vera tanaman diserahkanuntuk irigasi berbeda rezim di rumah kaca percobaan untuk mengevaluasi respon fisiologis proses seperti sebagai stomatalperlawanan dan aliran transpirasi serta pertumbuhan daun dan hasil. Percobaan terdiri dari tiga rezim irigasi di bawah benar-benardesain yang acak. Tidak ada efek awal pada stomatal resistensi atau aliran transpirasi dipamerkan, tetapi sebagai waktu berlalu perubahan inivariabel diperhatikan.Kami menyarankan bahwa kandungan air yang tinggi di parenchyma mempertahankan stomatal pembukaan meskipun tekanan air. Dalamperiode berikutnya, daun yang disampaikan air stres di awal, menunjukkan pengurangan pembukaan stomatal yang berkaitanpotensi air tanah yang rendah. Potensi air tanah rendah mengurangi berat daun, tingkat pertumbuhan tanaman dan daun nomor, terutama dalam pertumbuhan daunSelama percobaan mengkonfirmasikan sensitivitas dari daun baru air stres. Hasilnya menunjukkan bahwa rendah daun suhumeningkatkan stomatal perlawanan, menurunkan tingkat pertumbuhan tanaman dan daun. Perilaku ini adalah berlawanan dengan spesies lain CAM pada Semi-Aridkondisi.
