‘Syrgiannidis’ is an early-maturing pear cultivar originating from a cross between the cultivars Santa Maria and Kontoula (Greek local cultivar). Fruits are pyriform in shape with maximum diameter of ≈48 mm, mean fruit length 54 mm, and mean fruit

-set ( Lulai and Orr, 1993 ). Early-season tablestock cultivars are often grown as a spring crop to meet an early market window with high prices; however, they are typically harvested 90–120 d after planting (DAP) at which point the periderm is minimally mature

The floral abscission patterns of five early maturing pigeonpea genotypes; ICPL 146 1985HK, ICPL 87 Isotation (85K), ICPL 85010, ICPL 85024 and ICPL 8304 were studied on field grown plants in Missouri. Individual plants were bagged with nylon nets at the beginning of flowering, and the buds, flowers and pods were collected weekly and counted. Abscission began after anthesis and was excessive throughout most of the flowering period. The number of open flowers which abscised was much greater than that of buds or immature pods. The maximum number of weekly abscission of flowers per plant was 470 for ICPL 146 1985HK. Low night temperature below 10°C enhanced abscission of buds, flowers and immature pods in pigeonpea.

‘Fallglo’ is an early-season mandarin hybrid that was developed by Dr. C.J. Hearn (USDA, ARS retired) and released by the USDA in 1987 ( Hearn, 1987 ). ‘Fallglo’ is self-compatible and produces early-maturing, attractive, high color fruit with a

The suspected contributory role of soil fertilization to nitrate pollution of groundwater has encouraged exploration of novel fertilizer management strategies. Foliar-applied urea has long been used to supplement soil N applications, but there have been no apparent attempts to replace soil N applications completely in deciduous orchard culture. Two experiments were conducted to study the effect of foliar-applied low biuret urea on productivity and fruit growth of the early maturing peach [Prunus persica L. Batsch (Peach Group)] cultivar, Early Maycrest. In a 3-year experiment, a total foliar urea regime was compared to an equivalent amount of N applied to the soil. The foliar treatment supplied adequate amounts of N to the various organs of the tree including the roots, shoots, and fruit buds, but mean fruit weights were lower than in the soil-fertilized treatment. In a 2-year experiment, a 50%-50% combination treatment of soil-applied N in late summer with foliar-applied N in October, maintained yields and fruit weight equal to the soil-fertilized control. Some soil-applied N appears necessary for optimum fruit growth. Soil N application may be needed to support root proliferation and associated processes, but we did not determine a threshold amount of soil-applied N needed. The combination treatment also reduced excessive vegetative growth which is characteristic of early maturing peach cultivars. Therefore, this combination treatment offers promise as a viable commercial practice for maintaining tree productivity and controlling excessive vegetative growth in peach trees.

Early maturing peach trees [Prunus persica (L.) Batsch cv. Regina] growing on a deep sandy loam soil were subjected to three levels of postharvest irrigation over 4 years. The control treatment was irrigated with ≈ 10 to 15 cm of water at 2- to 3-week intervals, the medium treatment received a single irrigation (20 to 30 cm) in early August, and the dry treatment was not irrigated between early to mid-June and mid-October. All received a predormancy irrigation of 10 to 15 cm in mid- to late October. Flower and fruit density were greater in the dry treatment than the control. The occurrence of double fruit was also greatly increased in the dry treatment but not in the medium treatment, when compared with the control. After normal commercial hand thinning, yields and fruit size were no different among the three treatments over all 4 years. Vegetative growth as measured by dormant pruning weights, trunk radial growth, and canopy shaded area was reduced in the dry treatment, but there was no indication of progressively declining vigor. Soil moisture determinations indicate that water use by the control occurred mainly in the upper soil profile. In the dry treatment, as the upper profile dried, water was extracted progressively deeper, down to at least 300 cm. The main disadvantage of severe postharvest water stress was the substantial increase of double fruits.
