The present studies report in vitro propagation of a rare and medicinally important orchid Vanda testacea through foliar explants. Explants were cultured on Mitra et al. (M) medium and its combinations with cytokinins (BAP, Kn 1 mgl each) and auxin (NAA 1 mgl) individually and in combination for initiation of regeneration response, proliferation of regenerants and subsequent development of plan...

Interspecific hybridization in Tecoma Juss. was conducted to develop novel forms for the nursery industry. We report fertile hybrids from the cross T. garrocha Hieron. (pistillate parent) × T. stans (L.) Juss. ex Kunth. Leaf morphology of the F(1) hybrids of T. garrocha × T. stans was intermediate between the parents. GISH also confirmed hybridity. The F(1) hybrids were successfully backcross...

Lan hài Đốm (Paphiopedilum concolor Lindl. Pfitz) là loài bản địa của miền Bắc Việt Nam. Hiện nay, này đã bị khai thác cạn kiệt ngoài tự nhiên nên việc phát triển phương pháp nhân giống in vitro để bảo tồn rất cần thiết. Bài báo trình bày kết quả nghiên cứu về một số yếu tố ảnh hưởng đến hiệu bao gồm môi trường khoáng phù hợp cho hạt nảy mầm, cây con từ hạt, tái sinh chồi và trưởng vitro. Kết t...

Solid-state (13)C nuclear magnetic resonance (NMR) spectra of the following intact plant tissues were recorded by the crosspolarization magic-angle spinning technique: celery (Apium graveolens L.) collenchyma; carob bean (Ceratonia siliqua L.), fenugreek (Trigonella foenum-graecum L.), and nasturtium (Tropaeolum majus L.) endosperm; and lupin (Lupinus polyphyllus Lindl.) seed cotyledons. All th...

A new acylated triterpene together with prunasin, (-)-epicatechin, daucosterol, and three triterpenes, ursolic, oleanolic, and pomolic acids was isolated from the root of Chaenomeles japonica (THUNB.) LINDL. (Rosaceae) and determined to be 3-O-(E)-3, 5-dihydroxycinnamoylursolic acid on the basis of NMR and FAB-MS experiments.
