“…On the other hand, it is difficult to establish various leaf nutrient norms due to divergences of soil type, diagnosis time, and the methods to standardize the norms. In fact, a tentative nutrition program, illustrating the fertilizer choices based on phenological stage of lychee, was suggested in Australia (Martínez-Bolaños, 2020). Nowaday, appropriate fertilization by leaf nutrients diagnosis to the phytoprotection (e.g.…”

The steady production of Yuhebao lychee (Litchi chinensis Sonn.) is involved in accurate fertilization management. The critical period of nutrient requirement for Yuhebao lychee is during January to June every year in Taiwan because the period is from flowering to fruiting stage. It would serve the references of fertilization if there is an accurate standard for nutrient management of Yuhebao lychee. This study was conducted to establish the accurate standard of sampling period and location for nutrient diagnosis of Yuhebao lychee by analyzing essential nutrient elements of leaves from preanthesis to harvest stage. The leaves were sampled every month on middle of January to June for the estimation of leaf nutrients by inductively coupled plasma spectrophotometer (ICP). The results revealed that the appropriate sampling position and period of leaves should be from the leaves below flower spike during the flowering period. On the other hand, the mature leaves from either the branch of flowering or non-flowering terminal for nutrient management of Yuhebao lychee is recommended.

Summary A new species of stubby root nematode, Trichodorus lownsberyi sp. n., collected from soil around Buxus sempervirens at Montecillo Campus, Colegio de Postgraduados, Mexico, is described and illustrated. Trichodorus lownsberyi sp. n. is characterised by the abundant males with a characteristic spicule shape, the narrower part about mid-blade having visible bristles in most specimens, and the presence and position of the three ventromedian cervical papillae, which are all anterior to the secretory-excretory pore. Females possess a rhomboid-shaped vagina and oval to rounded triangular vaginal sclerotised pieces with a pore-like vulva. The phylogenetic relationships of T. lownsberyi sp. n. with related species were constructed using the ITS2 rRNA and the D2-D3 expansion segments of 28S rRNA gene sequences. Trichodorus lownsberyi sp. n. was a sister species to T. viruliferus in the phylogenetic trees. A Mexican population of Nanidorus minor from a peach orchard is also described and illustrated. The new needle nematode, Longidorus quercus sp. n., was recovered from soil around roots of oak, Quercus crassipes, from Cerro Jusda ‘El Diablo’ in Mexico State. Longidorus quercus sp. n. females are characterised by the C-shaped posterior end of the body after fixation, L = 4.9 (3.9-5.6) mm, a = 71 (60.8-93.2), lip region rounded, sometimes slightly flattened, marked by depression, odontostylet 170 (144-206) μm long, hemispherical to bluntly conoid tail and no males. The new species was characterised using the D2-D3 of 28S rRNA and COI gene sequences. The phylogenetic relationships of L. quercus sp. n. with other Longidorus species were reconstructed using the D2-D3 of 28S rRNA gene sequences.
